Topic: I have an unusual problem powering muscle wires (Read 778 times) previous topic - next topic


I have this art piece that I'm working on that uses 8 short pieces of muscle wire. I have power going through relays that are controlled through the arduino. When have the power going to the muscle wires through a 3v battery pack, the piece works perfectly, but when I switch over to a 3v wall adapter it doesn't work and I get a zero volt reading coming from the wall adapter. The wall adapter  works on it's own , just not with the muscle wires, and I've tried changing the adapter for a new one, but the issue persists. Please help


I think muscle wires take a lot of current which the wallwart may not be capable of supplying. You probably need a bigger power supply.
