I have a strip of LEDs that I want to illuminate stuff (workbench photography etc.) that are in parallel. If I have a fixed power supply say 6v and I want to be able to dim the lights without using any microcontrollers from fully on to nearly off (I would use a switch to guarantee that they are entirely off) how would I do that? Is it really as simple as a potentiometer and if so how would I determine what kind.
I will have 16 LEDs with a forward current of 20mA and 3.4V. Thanks for your help in advance.
