Introduction: 12-Bit RGB LED Ring - Lilypad Arduino
After spending 1 hour to complete my knight rider project I decided to try the much easier task.
Ring was purchased here
You have to download the library from Adafruit here
You can find the code attached.
It requires 3 wires and the work is done ... Not much to say about it.
You can change the speed ... but it took 5 minutes.
