Check out the “Making of” tab for step by step process for making these.
This tying trigger has 4 legs. One leg acts as the positive and the other three correspond to three different actions. Tie the positive leg with any of the other legs on to the same conductive object to activate the desired action.
In this prototype the legs are connected to the RGB LED. Thus each of the three legs correspond to a different color. Try different tying combinations and find appropriate objects to trigger different color!
