I’m new to this forum (and new to electronics). For an art project I would like to make a rotating arm that simply rotates slowly and knocks things over, and writes on the floor. For the time being I would like some advice on the first step, i.e. How to get something to rotate slowly.
I have a 2rpm gear motor, a potentiometer, some wires, and a 9v battery. Once I connect these together are there any recommendations on what to mount to the motor?
