Okay, apologies for the dumb questions.. enthusiastic but unscientific newbie.
I bought a 12v relay kit and assembled it, (the Kemo, B197), hoping to trigger a motor when an led is triggered by a 555 timer. no luck.
1. Im sure I tried 12v, but 9v was easier.. Would a 12v relay need to be powered by the full 12v ? (relay is 1xON 6/3 amp)
2. The negative of the relay circuit appears to go somewhere else, would this be the negative of the "motor circuit" or the negative of the 555 circuit?
3. This still requires power to the motor right? And the relay circuit simply acts as a mechanical switcher.. Would I hear it switch if that bit was working? Is it because the motor needs too much torque to start up, its just a tiny hobby type motor? Is it because the led's flash kinda fast?
4. Okay, what I really just want to do is build a mechanical drum machine, where 555 timers trigger toy motors that hit things... trying to find the answer here I get the impression just a transistor could do this? I dont care about blowing the whole thing up, and, it will all be 9v DC if I can possibly help it.
Thanks so much for any help, the instructions on the kit were very poor, and Im really still just at the stage of copying simple circuits and trying to get a clue what they do... Lots of possible combinations even with a few components when you are a moron!
