You can easily wire this breakout to any microcontroller, we'll be using an Arduino. For another kind of microcontroller, as long as you have I2C pins available, just check out the library, then port the code.
Wiring
Wire as shown for a 5V board like an Uno. If you are using a 3V board, like an Adafruit Feather, wire the board's 3V pin to breakout VIN.
Here is an Adafruit Metro wired up to the LED driver using the STEMMA JST PH cable:
- Board 5V to breakout VIN
- Board GND to breakout GND
- Board SCL to breakout SCL
- Board SDA to breakout SDA
Download Libraries
To begin reading sensor data, you will need to dowload the Adafruit IS31FL3731 library from the Arduino library manager.
Open up the Arduino library manager:
Search for the Adafruit IS31FL3731 library and install it
Search for the Adafruit GFX library and install it
If using an older (pre-1.8.10) Arduino IDE, locate and install Adafruit_BusIO (newer versions do this one automatically).
We also have a great tutorial on Arduino library installation at:
http://learn.adafruit.com/adafruit-all-about-arduino-libraries-install-use
Load Demo
Open up File->Examples->Adafruit_IS31FL3731->swirldemo and upload to your Arduino wired up to the driver & matrix
Upload to your Arduino, you'll see the LED display swirl different brightnesses!
