This Forum is awesome! Great Web Site!


fyi guys using a rester is fine when you are doing just one led here and there however if you are trying ro light up your bot, create a underglow or whatever that will require two to four leds its better to just series them to correct voltage. resisters place a additional load which is dispersed as heat to simulate another led being there to make the correct voltage. like i said one led by itslef is fine fo led but i avoid them so im not wasting power and creating additional heat. blue, green, yellow, purple, uv, pink, white leds operate from 3.0v to 3.7v red and ir are 2v to 2.5v
