Hi Everyone,
I'm not really an electronics guy, but I'm trying to wire up a simple circuit to control my projector mount with the projector's trigger circuit. I have figured out most of it but ran into a small problem. The projector's trigger is 12V 2.4 mA and the relay I have is 12 V 30mA. I have gathered that I need a transistor to boost the current so that it can trigger the relay. What I don't understand is which transistor to buy, how to wire it, and what resistors and diodes I need (if any).
Any help is appreciated.
Thanks,
Joe
