Just a quick video demonstrating the skeleton program for controlling lights on an RC truck (Axial Honcho) from the transmitter with only a 2 position switch (Ch3) to control normal/mode selection, and the steering to choose the mode.

The box can currently handle 8 LED channels, such as brake/tail, headlight, left indicators etc.
It gets it’s channel information from the 3 servo connectors on the receiver.

I’m also considering ways to monitor the motor speed, with that and the throttle position it will be possible to work out when your driving in reverse, so turning on a reversing light.

And yes, thats an Arduino, a Pro mini at 8MHz on 3.3v.
