    Adafruit Photo cell (CdS photoresistor) [ADA161]

    -Titulo Original : Adafruit Photo cell (CdS photoresistor) [ADA161]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 161 // Stock Type: Sensors >> Light/Color/Photo // In Stock & Ready to Ship // CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When its light, the resistance is about 5-10KΩ, when dark it goes up to 200KΩ.To use, connect one side of the photo cell (either one, its symmetric) to power (for example 5V) and the other side to your microcontroller's analog input pin. Then connect a 10K pull-down resistor from that analog pin to ground. The voltage on the pin will be 2.5V or higher when its light out and near ground when its dark. CdS photocells are not RoHS compliant , so if you need something equivalent but RoHS compiant, check out the photo transistor.

    Adafruit Pro Trinket - 3V 12MHz

    -Titulo Original : Adafruit Pro Trinket - 3V 12MHz-Fabricante : Adafruit-Descripcion Original: The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes // ATmega328P onboad chip in QFN package running at 3.3V logic // Micro-USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram. // Trinket's got a big sister in town - the Pro Trinket 3V! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328. It's like an Arduino Pro Mini with more pins and USB tossed in. Trinket's a year old now, and while its been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM. That's why we designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. Like the Trinket, it has onboard USB bootloading support - we opted for a MicroUSB jack this time. We also added Optiboot support, so you can either program your Pro Trinket over USB or with a FTDI cable just like the Pro Mini and friends. The Pro Trinket PCB measures only 1.5 x 0.7 x 0.2 (without headers) but packs the same capability as an Arduino UNO. So it's great once you've finished up a prototype on an official Arduino UNO and want to make the project smaller. The Pro Trinket 3V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. However, it uses 3V logic and 12MHz clock which means it's good when you want a lower-power and lower-voltage setup. Pro Trinket is programmable using the Arduino IDE as you already set up, and 95% of Arduino projects will work out of the box! Here's some things you may have to consider when adapting Arduino sketches: Pins #2 and #7 are not available (they are exclusively for USB) The Pro Trinket 3V runs at 12MHz, this doesn't affect most projects. Only the most timing-specific libraries may be affected, check the documentation! The NeoPixel Library works fine at 12MHz. The onboard power supply is a 3.3V regulator and it can provide 150mA output You cannot plug shields directly into the Pro Trinke...

    Adafruit Pro Trinket 5v 16mhz (1 Unidad)

    -Titulo Original : Adafruit Pro Trinket 5V 16MHz (1 Piece)-Fabricante : Adafruit -Descripcion Original: Chip integrado ATmega328P en paquete QFN Velocidad de reloj de 16MHz, FLASH de 28K disponible El cargador de arranque USB con un buen indicador LED se parece a un USBtinyISP para que pueda programarlo con AVRdude y / o Arduino IDE (con algunas modificaciones simples de configuración). También tiene encabezados para un puerto FTDI para reprogramación Conector micro-USB para alimentación y / o carga USB, puede colocarlo en una caja o pegarlo con cinta adhesiva y usar cualquier cable USB para cuando desee reprogramar. Regulador de potencia incorporado de 5.0V con capacidad de salida de 150mA y caída ultra baja. Entrada de hasta 16 V, protección de polaridad inversa, protección térmica y de límite de corriente. Trinket tiene una hermana mayor en la ciudad: ¡Pro Trinket 5V! Pro Trinket combina todo lo que te gusta de Trinket con la familiaridad del chip Arduino de núcleo común, el ATmega328. Es como un Arduino Pro Mini con más pines y USB, tan delicioso. Trinket ya tiene un año, y aunque ha sido genial ver toneladas de pequeños proyectos, a veces solo necesitas más pines, más FLASH y más RAM. Es por eso que diseñamos Pro Trinket, con 18 GPIO, 2 entradas analógicas adicionales, 28K de flash y 2K de RAM. Al igual que el Trinket, tiene soporte de carga de arranque USB integrado: esta vez optamos por un conector MicroUSB. También agregamos el soporte Optiboot, para que pueda programar su Pro Trinket a través de USB o con un cable FTDI al igual que el Pro Mini y sus amigos. El Pro Trinket PCB mide solo 1.5 x 0.7 x 0.2 (sin encabezados) pero tiene casi la misma capacidad que un Arduino UNO. Por lo tanto, es excelente una vez que haya terminado un prototipo en un Arduino UNO oficial y quiera hacer el proyecto es más pequeño. El Pro Trinket 5V usa el chip Atmega328P, que es el mismo chip central en el Arduino UNO / Duemilanove / Mini / etc. a la misma velocidad y voltaje. Por lo tanto, le alegrará saber que no solo es Pro Trinket programable usando el IDE de Arduino como ya configuró, ¡pero el 99% de los proyectos de Arduino funcionarán de inmediato! Aquí hay algunas cosas que debe tener en cuenta al adaptar los bocetos de Arduino: los pines # 2 y # 7 no están disponibles (están exclusivamente para USB) El regulador de 5 V integrado puede proporcionar una salida de 150 mA, no una salida de 800 mA. No puede enchufar los protectores directamente en Pro Trinket. No hay un chip de serie a USB integrado. Esto es para mantener el Pro Trinket pequeño y económico, puede usar cualquier cable FTDI para conectar al puerto FTDI para una conexión en serie. nnection es solo para cargar código nuevo. El gestor de arranque en Pro Trinket usa 4KB de FLASH, por lo que el tamaño máximo de boceto es de 28,672 bytes. El gestor de arranque no afecta el uso de RAM...

    Adafruit Pro Trinket Liion/lipoly Backpack Add-on

    -Titulo Original : Adafruit Pro Trinket LiIon/LiPoly Backpack Add-On-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2124 // Stock Type: Power >> LiIon & LiPoly >> Accessories // In Stock & Ready to Ship // If you have a Pro Trinket you probably know it's the perfect little size for a portable project. This LiPoly backpack makes it really easy to do! Instead of wiring 2 or 3 boards together to make a charging system, this little PCB sits on top of the Pro Trinket and allows a LiPoly/LiIon battery to plug in. When the Pro Trinket USB port is powered, the battery is recharged automatically. Unplug the USB port and the Pro Trinket will switch over to the rechargeable battery.Ideally, this backpack is for use with the 3.3V Pro Trinket, so that the battery voltage (3.7V-4.2V) will get regulated down to 3.3V on the Pro Trinket board. However, many times, you can run a 5V Pro Trinket + accessories off of the ~4V from the LiPoly battery with no problem. (Technically its overclocking but we've never seen that affect the Pro Trinket itself, AVRs are happy to overclock without complaint).Solder the backpack on with the extra long header so that it can still plug into a breadboard, or clip the long header leads short afterwards for a slim package. There are two LEDs - one red and one green. While charging, the red LED is lit. When the battery is fully charged and ready for use, the green LED turns on. Seriously, it could not get more easy.If you want to add an On/Off switch, we also made that really easy. The two 0.1 holes with a box around them are the battery output line. Carefully cut the trace between them with a hobby knife and replace with two wires from a switch like this slide switch , or this pushbutton one , for example. Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up. The charge current is 100mA by default, so it will work with any size battery and USB port. If you want you can easily change it over to 500mA mode by soldering closed the jumper on the bottom, for when you'l...

    Adafruit Resistive Touch Screen to USB Mouse Controller - AR

    -Titulo Original : Adafruit Resistive Touch Screen to USB Mouse Controller - AR1100-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1580 // Stock Type: Breakout Boards >> Touch // In Stock & Ready to Ship // Getting touchy performance with your screen's touch screen? Resistive touch screens are incredibly popular as overlays to TFT and LCD displays. If you want to connect one to a computer you need something to handle the analog to digital conversion. Most converters we've found are not very easy to use, and are 'fixed' - making them difficult to calibrate. The AR1100 is a nice chip that solves this problem by acting as a touch->USB converter and also comes with calibration software. The calibration software is Windows only, but once you've calibrated you can use the screen on any OS. The AR1100 shows up as a regular Mouse or Digitizer HID device so no drivers are required. We've tested it sucessfully on Mac, Windows, and Debian Linux (Raspbian on a Raspberry Pi). Other Linux distributions may or may not work, but if you're running Linux you're probably used to that.This breakout board features the AR1100, which has both USB and UART interfaces available. 99% of the time, you'll want to use the USB interface but there is some functionality for getting TTL UART data out (see the datasheet for details) There is also a red LED that lights up to indicate when a touch has been detected. For the screens that have 1mm pitch FPC cables, you can plug the cable right into the connector. The majority of medium/large touchscreens have that kind of connector. If you have another kind of touch screen, the four X/Y contacts are available on 0.1 pitch breakouts so you can hand-solder or wire them. We set this breakout up for 4-wire sensing only. You can pretty much just plug and play to get started, for more details including calibration software, check out the AR1100 page . Plug any 1mm-pitch 4-wire resistive touchscreen to the on-board FPC connector, when you plug into a computer's USB port you should see a new device and touching the screen will cause the mouse cursor to move around...

It can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and 'act' like a NFC tag. If you want to do any sort of embedded NFC work, this is the chip you'll want to use!NFC (Near Field Communications) is a way for two devices very close to each other to communicate. Sort of like a very short range bluetooth that doesn't require authentication. It is an extension of RFID, so anything you can do with RFID you can do with NFC. You can do more stuff with NFC as well, such as communicate bi-directionally with cell phonesBecause it can read and write tags, you can always just use this for RFID-tag projects. We carry a few different tags that work great with this chip. It can also work with any other NFC/RFID Type 1 thru 4 tag.The PN532 is also very flexible, you can use 3.3V TTL UART at any baud rate, I2C or SPI to communicate with it. This chip is also strongly supported by libnfc , simply plug in an FTDI cable and use the FTDI serial port device to communicate - this lets you do NFC dev using any Linux/Mac/Windows computer! We also include onboard power LED, 3.3V regulator and an FTDI header so you can plug in an FTDI friend or FTDI cable and use with libnfc.Comes with: the PN532 breakout board including a tuned 13.56MHz stripline antenna, 0.1 header, 2 jumpers/shunts and a 4050 level shifter chip.

    Adafruit Rotary Encoder (1 piece)

    -Titulo Original : Adafruit Accessories Rotary Encoder (1 piece)-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 377 // Stock Type: Sensors >> Touch // In Stock & Ready to Ship // This rotary encoder is the best of the best, its a high quality 24-pulse encoder, with detents and a nice feel. It is panel mountable for placement in a box, or you can plug it into a breadboard (just cut/bend the two mechanical side tabs.) We also include a nice soft-touch knob with an arrow in it, fits perfectly and looks great. This encoder also has a push-button built into it so you can press onto the knob to close a separate switch. One side has a 3 pin connector (ground and two coding pins) and the other side has two pins for a normally-open switch.Rotary encoders are useful as rotation sensors or selectors and look similar to potentiometers. However they are not like potentiometers at all, so it's important to realize the difference! These rotary encoders rotate all the way around continuously, and are divided up into 24 'segments'. Each segment has a click-y feeling to it, and each movement clockwise or counter-clockwise causes the two switches to open and close. There is no way to know what the current 'position' is - instead you would use a microcontroller to count how many 'clicks' left or right it has been turned. If you need to detect rotational 'position' a potentiometer would be a better choice...

They are simple to use and low cost. This sensor is a Interlink model 402 FSR with 1/2 diameter sensing region.FSR's are basically a resistor that changes its resistive value (in ohms Ω) depending on how much its pressed. These sensors are fairly low cost, and easy to use but they're rarely accurate. They also vary some from sensor to sensor perhaps 10%. So basically when you use FSR's you should only expect to get ranges of response. While FSRs can detect weight, they're a bad choice for detecting exactly how many pounds of weight are on them.FSRs are made of plastic and the connection tab is crimped on delicate material. The best way to connect to these is to simply plug them into a breadboard or use a clamp-style connector like alligator clips, female header, or a terminal block. It is possible to solder onto the tabs but you must be very fast because if your iron is not good quality or you dally even a few seconds, you will melt the plastic and ruin the FSR!

    Adafruit SGP30 Air Quality Sensor Breakout - VOC and eCO2 (3

    -Titulo Original : Adafruit SGP30 Air Quality Sensor Breakout - VOC and eCO2 (3709)-Fabricante : ADAFRUIT-Descripcion Original: fully integrated MOX gas sensor // output signals with a typical accuracy of 15% // This part will measure eCO2 // Breathe easy with the SGP30 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing and fully calibrated output signals with a typical accuracy of 15% within measured values. The SGP combines multiple metal-oxide sensing elements on one chip to provide more detailed air quality signals. This is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C. The SGP30 has a 'standard' hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, tracks the baseline calibration, calculates TVOC and eCO2 values, and provides an I2C interface to read from. Unlike the CCS811, this sensor does not require I2C clock stretching. This part will measure eCO2 (equivalent calculated carbon-dioxide) concentration within a range of 0 to 60,000 parts per million (ppm), and TVOC (Total Volatile Organic Compound) concentration within a range of 0 to 60,000 parts per billion (ppb). Please note, this sensor, like all VOC/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources! That said, for general environmental sensors, it will give you a good idea of trends and comparison. The SGP30 does have built in calibration capabilities, note that eCO2 is calculated based on H2 concentration, it is not a 'true' CO2 sensor for laboratory use. Another nice element to this sensor is the ability to set humidity compensation for better accuracy. An external humidity sensor is required and then the RH% is written over I2C to the sensor, so it can better calculate the TVOC/eCO2 values...

They were popularized by being used in the Nintendo PowerGlove as a gaming interface. These sensors are easy to use, they are basically resistors that change value based on how much their flexed. If they're unflexed, the resistance is about ~25KΩ. When flexed all the way the resistance rises to ~100KΩ. They're pretty similar to FSRs so following this tutorial will get you started . You can use an analog input on a micro-controller (with a pullup resistor) or a digital input with the use of a 0.1uF capacitor for RC timing. The bottom part of the sensor (where the pins are crimped on) is very delicate so make sure to have strain relief - such as clamping or gluing that part so as not to rip out the contacts...

    Adafruit Speakers & Transducers Thin Plastic Speaker w/Wires

    -Titulo Original : Speakers & Transducers Thin Plastic Speaker w/Wires - 8 ohm 0.25W (1 piece)-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1891 // Stock Type: Components & Parts >> Speakers // In Stock & Ready to Ship // Listen up! This 1.5 diameter speaker cone is the perfect addition to any audio project where you need an 8Ω impedance and are using 0.25W of power. The speakers are rated at 0.25W, with a maximum input of 0.5W (printed wattage on back of speaker may have either value).We particularly like this cone as it's very simple and its plastic body is extremely lightweight and thin. Originally designed for 'talking' greeting cards, its fairly loud yet lightweight. Works great with our Wave shield or class D amplifier board . Just be careful not to overdrive the speaker as high volumes can blow it out! Start with lower volume and increase carefully...

    Adafruit Standalone Momentary Capacitive Touch Sensor Breako

    -Titulo Original : Adafruit Standalone Momentary Capacitive Touch Sensor Breakout-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1374 // Stock Type: Sensors >> Touch // In Stock & Ready to Ship // This breakout board is the simplest way to create a project with a single momentary capacitive touch sensor. No microcontroller is required here - just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. When a capacitive load is detected (e.g. a person touches the sensor-pad area) the red LED lights up and the output pin goes high. You can also solder a wire to the middle pad and create your own capacitive pad if the built-in one isn't suited to your project. If you want to save power, the LED can be disconnected from the output pin (cut the trace between the jumper marked as such). We designed this breakout to have the more-responsive fast mode which draws about 0.5mA. If you need ultra-low (~50uA) power usage, the mode jumper can be cut on one side & soldered closed on the other to fix it into that mode. Check the datasheet for specific power usage measurements. Comes with a fully assembled board, and a small stick of 0.1 header so you can solder and plug it into a breadboard. For additional contacts, we suggest using copper foil, then solder a wire that connects from the foil pad to the breakout. The datasheet has many details on sensitivity, power usage, etc. Standalone Momentary Capacitive Touch Sensor Breakout ( 11:10 ...

    Adafruit Standalone Toggle Capacitive Touch Sensor Breakout

    -Titulo Original : Adafruit Standalone Toggle Capacitive Touch Sensor Breakout - AT42QT1012 [ADA1375]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1375 // Stock Type: Sensors >> Touch // In Stock & Ready to Ship // This breakout board is the simplest way to create a project with a single toggle capacitive touch sensor. No microcontroller is required here - just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. This sensor is a toggle output type: touch-on then touch-off. That means that when a capacitive load is detected (e.g. a person touches the sensor-pad area) the red LED will alternate turning off and the output pin will go high or low, respectively. This sensor is good for a project where you want to activate something on the first touch, then deactivate it when touching again, like a switch. You can also solder a wire to the middle pad and create your own capacitive pad if the built-in one isn't suited to your project. If you want to save power, the LED can be disconnected from the output pin (cut the trace between the jumper marked as such). We designed this breakout to have infinite time-out. The chip does support having the sensor time-out, so for example, if something is turned on, it will eventually turn off on its own. If you'd like to use this mode, cut the TIMER jumper and then connect a resistor/capacitor to the TIME pin. Check the datasheet for how to calculate the TIME pin to match your desired timeout. Comes with a fully assembled board, and a small stick of 0.1 header so you can solder and plug it into a breadboard. For additional contacts, we suggest using copper foil, then solder a wire that connects from the foil pad to the breakout.

    Adafruit Stereo 2.1W Class D Audio Amplifier - TPA2012

    -Titulo Original : Adafruit Stereo 2.1W Class D Audio Amplifier - TPA2012-Fabricante : ADAFRUIT-Descripcion Original: Output Power: 2.1W at 4Ω, 10% THD, 1.4W at 8Ω, 10% THD, with 5V Supply // PSRR: 77 dB typ @ 217 Hz with 6 dB gain // Designed for use without an output filter, when wires are kept at under 2"-4" long // Four pin-selectable gains: 6dB, 12dB, 18dB and 24dB. Select with the onboard switches or by setting the G0 and G1 breakout pins // Thermal shutdown protection // This incredibly small stereo amplifier is surprisingly powerful - able to deliver 2 x 2.1W channels into 4 ohm impedance speakers (@ 10 pct THD). Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, it's incredibly efficient (89 pct efficient when driving an 8 ohm speaker at 1.5 Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. This board is a welcome upgrade to basic LM386 amps. The inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the R- and L- to ground. The outputs are Bridge Tied - that means they connect directly to the outputs, no connection to ground. The output is a ~300KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly. Comes with a fully assembled and tested breakout board with 1.0uF input capacitors. We also include a dual mini DIP switch for setting the amplifier gain on the fly, 3.5mm screw-terminal blocks so you can easily attach/detach your speakers, and some header in case you want to plug it into a breadboard. You will be ready to rock in 15 minutes. Speakers are not included, use any 4 ohm or 8 ohm impedance speakers. Output Power: 2.1W at 4 ohn, 10 pct THD, 1.4W at 8 ohm, 10 pct THD, with 5V Supply PSRR: 77 dB typ @ 217 Hz with 6 dB gain Designed for use without an output filter, when wires are kept at under 2-4 long Four pin-selectable gains: 6dB, 12dB, 18dB and 24dB. Select with the onboard switches or by setting the G0 and G1 breakout pins (see schematic for breakout board showing gain pin settings for details) Excellent click-and-pop suppression Thermal shutdown protection Independent channel shutdown Low current draw: typ 6mA quiescent and 1.5uA in shutdown mode Note: The terminal blocks included with your product may be blue or blac...

This slim little board has a class D amplifier onboard that can drive 2 channels of 4-8 ohm impedance speakers at 20W each. Power it with 5-12VDC using the onboard DC power jack and plug stereo line level into the 3.5mm stereo headphone jack and jam out with ease. Since it's class D, its completely cool-running, no heat sinks are required and it's extremely efficient - up to 93% efficiency makes it great for portable or battery powered rigs. We like the MAX9744 amplifier at the heart of this board because its very easy to use, but it also has both analog and digital volume control capability. Use a single 1KΩ pot (we include one) to adjust volume analog-style. Or hook it up to your favorite microcontroller and send I2C commands to set 64-steps of volume amplification. Some great stats about the MAX9744:Power from 4.5V-14V DC voltageUp to 93% efficient (88-93% typical)20mA quiescent current (or put into shutdown for 1uA quiescent)Up to 29.5dB max gainUse DC or AC coupled line-level input, up to 3VppFilterless Spread-Spectrum Modulation Lowers Radiated RF Emissions from Speaker Cables20W Stereo Output (4Ω, VDD = 12V, THD+N = 10%)Low 0.04% THD+NIntegrated Click-and-Pop SuppressionShort-Circuit and Thermal-Overload ProtectionWe took this lovely chip and wrapped it up into a breakout for you, with polarity-protection, jacks and terminal blocks, i2c level shifting, and a spot to solder in a volume pot.
