Though the Raspberry Pi computer is eminently networkable, some projects still just work best by physically moving the SD card to a desktop system to exchange data…but normally only a small section of the card is accessible to Windows and Mac computers. This guide explains one way of making more space available to both the Pi and other systems.
If your microcontroller or microcomputer has digital audio capability, this amp is for you! It takes standard I2S digital audio input and, not only decodes it into analog, but also amplifies it directly into a speaker. Perfect for adding compact amplified sound, it takes 2 breakouts (I2S DAC + Amp) and combines them into one.
You wont be able to look away from the mesmerizing patterns created by this Adafruit 15x7 CharliePlex LED Matrix Display FeatherWing. This 15x7 LED display can be paired with with any of our Feather boards for a beautiful, bright grid of 105 charlieplexed LEDs. It even comes with a built-in charlieplex driver that is run over I2C.
You will chirp with delight when you see how easy it is to make your very own 8x16 LED matrix display for any Feather. This kit combines two of our adorable miniature LED matrices with a FeatherWing driver board. At 0.8" square, these little 8x8 matrices have got everything a big LED matrix has, but bite sized! Double them up for 128 total bright LEDs.
Have some fun with the Adafruit Feather HUZZAH and the CheerLight project. Originally created by Hans Scharler, CheerLights allows people’s lights all over the world to synchronize to one color set by a specific Twitter feed. In this interpretation, Marc de Vinck creates a WiFi enable CheerLight using the Adafruit Feather HUZZAH, Neopixels, and some clever code.
Give your Feather a sense of place, with an Ultimate GPS FeatherWing. This FeatherWing plugs right into your Feather board and gives it a precise, sensitive, and low power GPS module for location identifcation anywhere in the world. As a bonus, the GPS can also keep track of time once it is synced with the satellites.
This is the Adafruit 0.56" 4-Digit 14-Segment Display w/ FeatherWing Combo Pack! Display, elegantly, 012345678 or 9! Gaze, hypnotized, at ABCDEFGHIJKLM - well it can display the whole alphabet. You get the point. It is a nice, bright alphanumeric display that shows letters and numbers in a beautiful hue.
7-Segment Matrices like these are 'multiplexed' - so to control all the seven-segment LEDs you need 14 pins. That's a lot of pins! Here at Adafruit we feel your pain. After all, wouldn't it be awesome if you could control a matrix without tons of wiring? That's where these 7-Segment LED FeatherWings come in!
Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While this chip has been very popular, its also been very difficult to use. Most of the low cost modules are not breadboard friendly, don't have an onboard 250mA 3.3V regulator or level shifting, and aren't CE or FCC emitter certified....UNTIL NOW!
Once you have mastered the basic blinking leds, simple sensors and buzzing motors, it’s time to move on to bigger and better projects. That usually involves combining bits and pieces of simpler sketches and trying to make them work together. The first thing you will discover is that some of those sketches that ran perfectly by themselves, just don’t play well with others. There are ways to effectively juggle multiple tasks on an Arduino. This series of guides will show you how.
