Fan Control Circuit (LM317) - This is an illustrated tutorial on building a variable voltage control for fans and other units, ba
This is an illustrated tutorial on building a variable voltage control for fans and other units, based on the LM317 regulator. It efficiently allows voltage adjustment from 1.25V to 11.5V with the turn of a knob.
