Ritschratsch

A framework for arduino to easily build sound machines from DC and servo motors, WS2812b led strips and trash. A lot of tape, zip ties and a glue gun is recommended.

How to use?

Ritschratsch can be used with any ATMega328 based microcontroller, an arduino nano is recommended though. There are predefined outputs for servo motors, DC motors controlled through a L298N H-bridge, a Neopixel style WS2812B LED strip and some general purpose outputs e.g. for single LED's, transistors or relays. All outputs (beside the one for the LED strip) can be programmed in a keyframe-ish way, which makes it quite easy to create even more complex patterns and behaviour. Depending on the kind of output informations like interval duration motor speed target angleetc. have to be provided, you can find more info about each output and how to use it in the example sketch.
