How to Control a Servo With an Arduino

This video tutorial guides viewers through controlling a servo motor using a potentiometer with an Arduino. It begins by listing the necessary materials, including an Arduino, breadboard, servo motor, potentiometer, wires, and power supply. The tutorial then provides step-by-step instructions for setting up the circuit, connecting the components, and writing the Arduino code. The code involves using the servo library, creating a servo object, and mapping potentiometer values to servo positions. Finally, the video concludes with testing the setup and encouraging viewers to explore more advanced circuits.

Explain how the signal from the potentiometer is converted to a rotational degree for the servo.

What is the final step after writing the code for the Arduino?
