Hi,
I'm *not* very savvy wrt electronics, so please keep your responses simple!!!! I'm an astronomy demonstrator and have got a 30mW green laser module which I want to use to make a pointer. It has 3 wires coming from the board: a red, a black and a yellow. I guess the red and black are +ve and -ve respectively, so what do I do with the yellow wire? The only other specs I have is "Working current: <280mA @ 3V input "
TIA
