How to wire a blue LED light to 2 AA batteries?
I want to know if it’s possible to wire a 2 AA battery pack to one blue LED light. The output of 2 AA alkaline batteries is 3v, but I don’t know what LED and resistor to buy. Please don’t tell me I would want to get a 4 AA battery pack, I need to be as cost efficient as possible.
get you a 2 AA battery holder, wire, and a 3 volt led. you won’t need a resister because 1.5 volts and 1.5 volts is 3.0 volts, so if you got a 3 volt led, you’d be fine. just put it all together, and take out a battery when not in use. go to radioshack.
