Since Seeedstudio’s “sample sketch” for the Rainbowduino is super confusing and too complicated for…most…every possible usage, i wrote this very basic and simple firmware: simple-rainbowduino-jmr.
Right now it can be used to drive a RGB-Matrix of LEDs. But since a lot of people, including myself, use the rainbowduino to drive individual leds, i also wrote a function to address single unicolor leds. however, this fun is right now buggy. actually it’s working in another project of mine, dunno why it doesnt work here…
so have a look at
v1 is the current version. feel free to add issues, to change the code, use it any way u want. also, i’d really appreciate help!
