3 LED light question Answered
I am just curious as to what I might need, if any for a resistor. I plan to run 3 white LED's, using a single 9v. I jumped ahead and hooked up one set to see how it works, and it seems to work great, each LED is packaged as running at 3.2v, so I figured 3 would be alright on a 9v battery. Is a resistor required or necessary if I multiply in this manner?
