LED CURCUIT Answered
I do not know very much about electronics in general but I would like to make a circuit that allows me to run a group of " LED " lights, maybe ( 6 to 8 ) in PARALLEL. I would also like to do the same for hand held " Lasers " ( 3 to 4 ) in PARALLEL. To make it more complicated, I would like to be able to use the same power source to run both groups at the same time. I would like to be able to turn either group on or off independently while using the same power source. The power source will either be --2 D cell -- or -- 4 AA -- batteries. Normally each LED uses 3 hearing aid batteries. This is the same for each LASER pointer. I think each hearing aid battery is about 1.5 volts but Im not sure what the amperage is. I would like to do it as simple as possible. I hope I can get all of the parts at Radio Shack. I have no idea where to start, any help would be appreciated !
