Driving three servos with potentiometers on Arduino

This is really simple setup where you can drive three servo motors by turning potentiometers. It really takes few lines of code and minimal circuit setup, but if you look more deeply at this solution you can find many uses of it. Simply you can build a remotely controlled rig which could do some fancy stuff. This can be a small robot arm which can be further extended by adding magnetic actuator and so on. If you need more degrees of freedom, keep adding more pots and servos. Continue reading
