Help with LEDs and simple circuits? Answered
Okay, I'm making a little LED project and I'd like help on these following questions:
- On most switches there are three little prongs, which ones do I connect to which wires?
- Do I need a resistor for a simple, battery powered, LED circuit, with 16 LEDs? If so, what kind of battery do I need and what kind of resistor?
- Can LEDs shine through a thin layer (3-5 mm) of balsa wood?
