Demo an RGB LED module
Here's a quick video of the module in action:
The RGB LED module is a convenience since it builds-in 150Ω current-limiting resistors for the reg, green and blue anodes of a standard 5mm round RGB LED.
The demonstration program uses PWM to run a series of effects on the module.
NB: on my module, the red and blue pins are incorrectly labeled (swapped around).
