I'm modifying a chainsaw for halloween (which is very close, i know) and, instead of having the chain, I want to wire up a bunch of LEDs that alternate. Basically all i need is a circuit that alternates the output between two seperate drivers at a constant speed. And id like that speed to be relatively fast, or even adjustable. It would need to power upwards of 100 or so 20 mA, 3 VDC max LEDs so if i need to beef up the circuit, then so be it. If i had time and/or knowledge of what i was doing, i could very easily just research this myself but i was hoping here i can get explanations, kit options, and some choices in what im doing. Thanks!
