how can i set speeds with a potentiometer?
Hi there, Im busy building a metronome to fit a machine im altering, (the board was totally fried and rusted through) which also has a 6volt motor that spins in the front. I managed to find a potentiometer to control the speed of the motor and the metronome, but need to have set speeds on both of them. Is there anything that i can adapt to the potentiometers like a ratchet type system ? something maybe similar to a rotary switch that u click up and down? Im pretty new to all this, any help would be greatly appreciated. MGF
