    Adafruit DS3231 Precision RTC FeatherWing - RTC Add-on For F

    -Titulo Original : Adafruit DS3231 Precision RTC FeatherWing - RTC Add-on For Feather Boards [ADA3028]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 3028 // Stock Type: Development Boards >> Feather >> Wings // In Stock & Ready to Ship // A Feather board without ambition is a Feather board without FeatherWings! This is the DS3231 Precision RTC FeatherWing : it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO)  to any Feather main board. This RTC is the most precise you can get in a small, low power package. Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top of your Feather board and let the board take flight! Check out our range of Feather boards here. Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw. And that's all well and good, but those crystals have slight drift, particularly when the temperature changes (the temperature changes the oscillation frequency very very very slightly but it does add up!) This RTC is in a beefy package because the crystal is inside the chip! And right next to the integrated crystal is a temperature sensor. That sensor compensates for the frequency changes by adding or removing clock ticks so that the timekeeping stays on schedule.With a CR1220 12mm coin cell plugged into the top of the FeatherWing, you can get years of precision timekeeping, even when main power is lost. Great for datalogging and clocks, or anything where you need to really know the time. A CR1220 coin cell is required to use the battery-backup capabilities! We don't include one by default, to make shipping easier for those abroad,  but we do stock them so pick one up or use any CR1220 you have handy. Our tutorial for the DS3231 breakout has all the library and example code you need to get started, works with any and all of our Feathers via the Arduino IDE Check out our range of Feather boards here...
  • Adafruit EL Wire 2xAA Pocket Inverter [ADA317]
    Precio:  $54,389.00

    Adafruit EL Wire 2xAA Pocket Inverter [ADA317]

    -Titulo Original : Adafruit EL Wire 2xAA Pocket Inverter [ADA317]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 317 // Stock Type: EL Wire/Tape/Panel >> Inverters/Power Connectors // In Stock & Ready to Ship // A small, portable inverter for EL wire. Powers off of 2 AA batteries (not included!), it can drive 1 to 8 feet (about 2.5m) of our high-brightness EL wire for 10 hours. There is a button for selecting steady/blink/off modes. There's a removable clip on the back. Comes with a 2.5mm pitch female JST connectorTo connect a piece EL wire to this, you'll want a male connector wire The EL inverter requires a 'load' to stabilize itself. Otherwise the inverter can spike and damage itselfLike all inverters we've used, the 2000 Hz oscillation is slightly audible. To reduce the squeaking, we suggest opening up the case padding it with thick foam tape/weatherstripping . Squirting some hot glue around the capacitors may also help. We managed to get it silent this way. We used this to make our awesome TRON bag  Soldering to EL wire is a little tricky but luckily we wrote a detailed step-by-step tutorial...
  • Adafruit Electret Microphone Amplifier - Max9814 With Auto

    Adafruit Electret Microphone Amplifier - Max9814 With Auto

    -Titulo Original : Adafruit Electret Microphone Amplifier - MAX9814 with Auto Gain Control [ADA1713]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1713 // Stock Type: Sensors >> Sound/Noise // In Stock & Ready to Ship // Color: Add an ear to your project with this well-designed electret microphone amplifier with AGC. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX9814, a specialty chip that is designed for amplifying electret microphones in situations where the loudness of the audio isn't predictable. This fancy microphone amplifier module is a step above the rest, with built in automatic gain control. The AGC in the amplifier means that nearby 'loud' sounds will be quieted so they don't overwhelm & 'clip' the amplifier, and even quiet, far-away sounds will be amplified. This amplifier is great for when you want to record or detect audio in a setting where levels change and you don't want to have to tweak the amplifier gain all the time. The chip at the heart of this amp is the MAX9814 , and has a few options you can configure with the breakout. The default 'max gain' is 60dB, but can be set to 40dB or 50dB by jumpering the Gain pin to VCC or ground. You can also change the Attack/Release ratio, from the default 1:4000 to 1:2000 or 1:500. The ouput from the amp is about 2Vpp max on a 1.25V DC bias, so it can be easily used with any Analog/Digital converter that is up to 3.3V input. If you want to pipe it into a Line Input, just use a 1-100uF blocking capacitor in series (100uF sounds best). For audio-reactive projects, we suggest using an FFT driver library (such as the one in this library) which can take the audio input and 'translate' it into frequencies. If you just need to keep track of audio levels, see our sound-level meter tutorial for Arduino Each order comes with one assembled and tested board, with electret mic pre-soldered on, and a small piece of header. Our tutorial will get you started with using and testing the microphone amplifier and you can check out our general-purpose mi...

This Feather is fast like a swift, smart like an owl, strong like a ox-bird (it's half ox, half bird, OK?) This feather is powered by our new favorite chip, the ATSAMD51J19 - with its 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset. And best of all, it's a Feather - so you know it will work with all our FeatherWings! What a great way to quickly get up and running. The most exciting part of the Feather M4 is that while you can use it with the Arduino IDE - and it's bonkers fast when you do, we are shipping it with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with main.py on it. Edit main.py with your favorite text editor to build your project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can't install software on. When you're done, unplug the Feather and your code will go with you. The Feather M4 Express uses the extra space left over to add a Mini NeoPixel, 2 MB SPI Flash storage and a little prototyping space. You can use the SPI Flash storage like a very tiny hard drive. When used in CircuitPython, the 2 MB flash acts as storage for all your scripts, libraries and files.

    Adafruit Flora RGB Smart NeoPixel Version 2 - Pack of 4 [ADA

    -Titulo Original : Adafruit Flora RGB Smart NeoPixel Version 2 - Pack of 4 [ADA1260]-Fabricante : ADAFRUIT-Descripcion Original: Flora NeoPixels // Designed specifically for wearables // ultra-bright LED (each pixel can draw as much as 60mA) // High Speed 800KHz communication // Full 24-bit color ability with PWM taken care of by the controller chip // What's a wearable project without LEDs? Our favorite part of the Flora platform is these tiny smart pixels. Designed specifically for wearables, these updated Flora NeoPixels have ultra-cool technology: these ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable - so you only need 1 pin/wire to control as many LEDs as you like. They're easy to sew, and the chainable design means no crossed threads. This is the second version of the Flora NeoPixels, which runs at at 'high speed' 800KHz communication. Unfortunately they are not back-compatible with the chip-on-back 'low speed' (400KHz) Flora NeoPixels. If you have a project that already uses low speed pixels, and you want to attach more pixels to the chain, you will need to purchase version 1's as these are not cross-compatible. These pixels have full 24-bit color ability with PWM taken care of by the controller chip. Since the LED is so bright, you need less current/power to get the effects you want. The driver is constant current so its OK if your battery power changes or fluctuates a little. Each pixel draws as much as 60mA (all three RGB LEDs on for full brightness white). In theory, the Flora can drive up to 500 pixels at 30 FPS (it will run out of RAM after that). However, after about 10 pixels (or if the distance between pixels is more than an inch or two) the resistance of the thread can affect the power supply. For large quantities of pixels over 10, you may want to consider using stranded core wire or copper braid to provide a power bus for the pixels - the current draw will add up fast! Each order comes with 4 individually controllable pixels...

    Adafruit i2c / SPI Character LCD Backpack [ADA292]

    -Titulo Original : Adafruit i2c / SPI Character LCD Backpack [ADA292]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 292 // Stock Type: LCDs & Displays >> Character // In Stock & Ready to Ship // LCD backpacks reduce the number of pins needed to connect to an LCD. LCDs are a fun and easy way to have your microcontroller project talk back to you. Character LCDs are common, and easy to get, available in tons of colors and sizes. We've written tutorials on using character LCDs with an Arduino (or similar microcontroller) but find that the number of pins necessary to control the LCD can be restrictive, especially with ambitious projects. We wanted to make a 'backpack' (add-on circuit) that would reduce the number of pins without a lot of expense. By using simple i2c and SPI input/output expanders we have reduced the number of pins (only 2 pins are needed for i2c) while still making it easy to interface with the LCD. For Arduino users, we provide a easy-to-use library that is backwards compatible with projects using the '6 pin' wiring. The breakout comes with a 2-pin and 3-pin terminal block as shown (you can snap it together to make a 5-pin terminal and then solder it to the backpack for easy wiring) This backpack will work with any 'standard' character LCD, from 8x1 to 20x4 sizes! As long as they have a 16-pin single-line connection header at the top. We carry a few LCDs that work great . We suggest using our blue & white 20x4 or 16x2 LCDs. It does not work with the 16x2 OLED displays. You can try to connect our RGB 16x2 or 20x4 LCDs up but this backpack will not control the RGB backlight so you'll have to use the backpack only for the 14 digital IO pins (pins #1-14) and connect the backlight pins (#15-#18) directly to your microcontroller with 4 extra wires for color/PWM control as if they were just an RGB LED. For advanced users, this project can be used for general purpose I/O expansion, the MCP23008 has 8 i/o pins (7 are connected) with optional pull-ups, the SPI 74HC595 has 7 connected outputs.

Most people have seen inductive charging in a rechargable electric toothbrush: you may have noticed that you recharge it by placing it into the holder, but there's no direct plug. These chargers work by taking a power transformer and splitting it in half, an AC waveform is generated into one, and couples into the second coil. This is a basic charger set, and it does work, providing 5V DC output from the output half when the input half is powered with 9V to 12VDC. You can draw as much as ~500mA if the coils are 2 or 3 mm apart. If you only need 100 or 200mA you can be up 7mm apart. For 10mA draw, the coils can be up to half an inch (12.5mm) apart. Any non-ferrous/non-conductive material (eg air, wood, leather, plastic, paper, glass) can be used between the two coils. The material doesn't affect the distance or efficiency. The coils do need to be fairly co-axial, try to get them to be parallel and have the circles line up for best power-transfer. (This is why the electric toothbrush must fit into the plastic holder, it's lining up the two coils for best efficiency) Because its an air-core transformer, it's fairly inefficient. Only about 40% of the energy in shows up on the other end, but for low power or charging project. If you draw 5V 100mA on the output side (0.5W), you'll need 0.5W * 2.5 / 9V = ~150mA from the input end. The quiescent current is about 70mA at all time, even when the other coil is not anywhere near by. These are basic modules, probably used for some low cost toy. We don't have any datasheets or specifications for them. We do see a feedback resistor divider on the output side using 0...

They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between the two, and its not transparent to IR, then the 'beam is broken' and the receiver will let you know.Compared to PIR sensors, breakbeams are faster and allow better control of where you want to detect the motion. Compared to Sonar modules, they're less expensive. However, you do need both emitter and receiver on opposite sides of the area you want to monitor.This is the 5mm IR  version.   It works up to 50cm / 20. You can power it from 3.3V or 5V, but 5V will get you better range and is what we suggest. The receiver is open collector transistor output which means that you do need a pull up resistor if you want to read a digital signal off the signal wire. Most microcontrollers have the ability to turn on a built in pull up resistor. If you do not, connect a 10K resistor between the white wire of the receiver and the red wire. If you want to control a relay or LED or whatever, it can sink up to 100mA to ground Check out our IR breakbeam tutorial for how to get started quickly We also carry a 3mm version that works for slightly shorter distances...

    Precio:  $74,339.00

    Adafruit L3GD20H Triple-Axis Gyro Breakout Board - L3GD20/L3

    -Titulo Original : Adafruit L3GD20H Triple-Axis Gyro Breakout Board - L3GD20/L3G4200 Upgrade - L3GD20H [ADA1032]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1032 // Stock Type: Sensors >> Motion // In Stock & Ready to Ship // A gyroscope is a type of sensor that can sense twisting and turning motions. Often paired with an accelerometer, you can use these to do 3D motion capture and inertial measurement (that is - you can tell how an object is moving!) As these sensors become more popular and easier to manufacture, the prices for them have dropped to the point where you can easily afford a triple-axis gyro! Only a decade ago, this space-tech sensor would have been hundreds of dollars. This breakout board is based around the latest gyro technology, the L3GD20H from STMicro . It's the upgrade to the L3G4200 ( see this app note on what to look for if upgrading an existing design to the L3GD20 ) with three full axes of sensing. The chip can be set to ±250, ±500, or ±2000 degree-per-second scale for a large range of sensitivity. There's also built in high and low pass sensing to make data processing easier. The chip supports both I2C and SPI so you can interface with any microcontroller easily. Since this chip is a 3.3V max device, but many of our customers want to use it with an Arduino, we soldered it to a breakout board with level shifting circuitry so you can use the I2C or SPI interface safely using a 5V interface device. We also place a 3.3V regulator on there so you can power it from 5V. Since we expect people will want to attach it firmly to their project, the PCB comes with four 2.1mm mounting holes. Use #2-56 imperial or M2 screws screws. Getting started is easy - simply connect SDA to your Arduino I2C data pin (On the UNO this is A4), SCL to I2C clock (Uno: A5), GND to ground, and Vin to 3 or 5VDC. Then install and run our easy to use Arduino library, which will print out the XYZ sensor data to the serial terminal. Our library also supports SPI on any 4 digital I/O pins, see the example for wiring...

    Adafruit LED Lighting Development Tools 8-Channel PWM or Ser

    -Titulo Original : LED Lighting Development Tools 8-Channel PWM or Servo FeatherWing Add-on For All Feather Boards (1 piece)-Fabricante : ADAFRUIT-Descripcion Original: There's an I2C-controlled PWM driver with a built in clock. That means that, unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running! // It is 5V compliant, which means you can control it from a 3.3V Feather and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages) // 6 address select pins so you can stack up to 62 of these on a single i2c bus, a total of 992 outputs - that's a lot of servos or LEDs // Adjustable frequency PWM up to about 1.6 KHz // 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate // A Feather board without ambition is a Feather board without FeatherWings! This is the 8-Channel PWM or Servo​ FeatherWing, you can add 8 x 12-bit PWM outputs to your FeatherWing. Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top or bottom of your Feather board and let the board take flight! You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. What now? You could give up OR you could just get our handy PWM and Servo FeatherWing. It's a lot like our popular PWM/Servo Shield but with half the channels & squished into a nice small portable size and works with any of our Feather boards. Since the FeatherWing only uses the I2C (SDA & SCL pins), it works with any and all Feathers- ATmega32u4, ATSAM M0 or ESP8266-based. You can stack it with any other FeatherWing or with itself (just make sure you have each wing with a unique I2C address). This product comes with a fully tested and assembled wing as well as 2 pieces of 3x4 male straight header (for servo/LED plugs), a 2-pin terminal block (for power) and a stick of 0.1 header so you can plug into a Feather. A little light soldering will be required to assemble and customize the board by attaching the desired headers but it is a 15 minute task that even a beginner can do.

    Adafruit LED Lighting Development Tools NeoPixel FeatherWing

    -Titulo Original : LED Lighting Development Tools NeoPixel FeatherWing - 4x8 RGB LED Add-on For All Feather Boards-Fabricante : ADAFRUIT-Descripcion Original: A Feather board without ambition is a Feather board without FeatherWings! This is the NeoPixel FeatherWing, a 4x8 RGB LED Add-on For All Feather Boards! Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top or bottom of your Feather board and make your Feather board strut like a peacock at a rave. Put on your sunglasses before staring into these 32 configurable eye-blistering RGB LEDs. Arranged in a 4x8 matrix, each pixel is individually addressable. Only one pin is required to control all the LEDs. On the bottom we have jumpers for the DIN line to any of the I/O pins on a Feather. You can cut the default jumper trace and use any pin you like. To make it easy to start, the LEDs are by default powered from either the USB power line or Battery power line, whichever is higher. Two Schottky diodes are used to switch between the two. This power arrangement is able to handle 1 Amp of constant current draw and maybe 2A peak, so not a good way to make a flashlight. It's better for colorful effects. A level-up shifter converts the 3.3V logic of the Feather to the power line voltage. If, say, you need MORE blinky, you can chain these together. For the second Wing, connect the DIN connection to the first Wing's DOUT. Also connect a ground pin together and power with an independant 5V supply to keep from loading the power supply too much.

This 100mm diameter arcade button with a is so massive and inviting it may collapse upon itself and form a black hole from which not even light can escape! Until it does, however, it ready for all sorts of pressing and pushing. Science has shown no one can resist pressing its shiny surface and saying beep!. We've seen these on some games of skill in arcades, they're easy to mount on nearly any kind of enclosure. They're not waterproof or weatherproof, so best used indoors. This button has a domed red plastic cover with a black retaining ring around it. There's an optional LED included that will light up the button. The LED has a built in resistor so you can run it up to 12V but given the massive size and shallow depth of the button, it doesn't illuminate the entire button face evenly. The button activates a common arcade microswitch (included), the switch contacts are normally open. When the button is pressed, the contacts close.
