so say i was bored and wanted to try to make a fan controller (just vary the speed of the fan) could i use a pontentionmeter? 3 pins on a standard fan, one black, one red, one something else (tells rpm?)
how would i do this, i know a potentiometer has 3 inputs, one for power input, one for output, and one more to defien max amout of power.... where would i attach teh last one too? split the black of the fan into two? one for input and one for the max power lead?
