I finally got around to completing my musical colours project:
- Make the prototype permanent by building a perfboard arduino.
Includes the standard 5050 driver and usb to serial connection. I wanted to keep the standard 5050 controller for general van lighting, controllable by the IR remote. I did this by using another transistor as a switch for the 12v line into the controller. One of the routines in the code then pushes the gate high to turn the controller on.
