Control of a servomotor with a potentiometer (variable resistance by turning it).

Good morning,

Today we show you how to control a servo motor from left to right by turning a potentiometer (variable resistance), left or right.

The signal from the potentiometer reaches the Arduino via input A0 (input pin A0).

The Arduino is programmed to rotate the servo by sending the signal through the output (output 0).

Here we have the base to control a turn of a steering wheel... For example of a lunar vehicle!
