Can anyone help with a simple LED Design? Answered
Im looking to make a very simple circuit to add some lighting to a project. I want to create a circuit, powered by AA or AAA batteries that will power 6 LED lights (clear/white light) for up several hours. i know I need a power source (hopefully a simple battery holder with an on/off switch built in, a resistor and the set of LEDs (and wiring) what am I missing? which resistor am i looking for? How can I calculate battery life? Thanks for helping a new guy to electronics out!
