I have 2 seperate questions for the board here.
1) What can i use to Dim a cluster of LED's all at about 13.8V to 12V for the Voltage. I thought i could use a Variable resistor and a MOSFET, but im not sure now. because i think it was mentioned that it's bad to drive a MOSFET half-assed so to speak.
2) Which Value Variable Resistor should i use on the ground pin of a LM317 to make the output Voltages Variable between 0 or 1V to 24V? (the input is 24V+) I would like to make decent adjustments with a single turn Potientiometer.
Thanks Guys.
