Hello all,
I am very new to electronics so please excuse my ignorance, but I just got a sound activated kit from rainbow electronics. I want to hook up a small type 030 3V motor to it. The guy from rainbow sent a 5 v dpdt relay to use. So I have it all together and the circuit is working correctly, but the problem is with the relay and motor set up. I was told to run the motor parallel to the power source, so I currently have a 3v battery and the motor both running into one side of the relay, negatives in com, Positives in normally open(Which I hope means running in parallel) The motor will run for a while, when sound activated, but the battery is getting hot though and draining lots of power. The first problem is that I'm not really sure how a relay works? When I hook up the motor and power source in parallel the motor obviously runs, but when I solder them both to the relay, it does not run until switched. Hope you can help, and I wasn't too confusing. Thanks so much
