I was reading the instructions for this kit, and it says: “Replace the trimmer with a potentiometer of the same rating if you want to use the circuit as a permanently adjustable power supply.”
What exactly does this mean? I obviously want to use this for a wide variety of voltage outputs, I have to replace the potentiometer that is with the kit? Is this potentiometer not good for adjusting voltage? Is it because it requires a screwdriver to change voltage? What would be a suitable replacement?
