Adafruit AS7262 6-channel Visible Light Sensor
detect all the colors of the rainbow (except indigo)
by Dean Miller
A 6-channel visible light sensor breakout board that detects red, orange, yellow, green, blue, violet. All in one little I2C controlled package!
Native MP3 decoding on Arduino
play MP3 files with only your microcontroller
by Dean Miller
Playing MP3 audio files on an Arduino compatible board used to be a clunky and expensive ordeal. Now it's a breeze with the Adafruit MP3 library. If you have an ARM Cortex M4 (or M3) based microcontroller board, and you want to rock out, this mini guide will be music to your ears. With the accompanying library, based off of Helix, you will be able to decode and play stereo MP3 files without the need for an external chip! That's right, no VLSI VS10xx chips required, you can do it on the fly!
