Arduino Tutorial – Servo Motor Control with Potentiometer

Servo motors have three wires: power, ground, and signal. The power wire is typically red, and should be connected to the 5V pin on the Arduino or Genuino board. The ground wire is typically black or brown and should be connected to a ground pin on the board. The signal pin is typically yellow or orange and should be connected to pin 9 on the board.

 

The potentiometer should be wired so that its two outer pins are connected to power (+5V) and ground, and its middle pin is connected to analog input 0 on the board.

 

I recommend! You not connect directly the servo motor to the Arduino. I suggest you use external power to the servo. SG90 Mini Servo motors can be used.
