In this tutorial, we will learn how to use multi-servo with potentiometer. We will control 4 pcs servo motor with 4 pcs potentiometer.

You can implement your robotic arm projects with reference to this tutorial. Of course we will use external battery / power when doing this. In the next tutorial, I'll show you how to control servo motor with joystick.

Step 1: Hardware Required

- Arduino Board

- Servo Motor x4

-10k Potentiometer x4

- Battery

- Wires and Breadboard

Step 2: Connections

- The external battery VCC / GND connect to the breadboard.

- The Arduino GND connect to the breadboard's GND input

- The servo connections we use in this project are as follows;

Orange Input - Signal Input

Red Input - Power Input (VCC)

Brown Input - Ground Input(GND)

- The potentiometer connections we use in this project are as follows;

Two outer pins are power (VCC) and ground (GND)

Middle pin is signal pin

- The Servo1 VCC and GND connect to the breadboard's VCC / GND inputs

- The Servo1 Signal connect to the Arduino Digital PWM 3

- The Servo2 VCC and GND connect to the breadboard's VCC / GND inputs

- The Servo2 Signal connect to the Arduino Digital PWM 5

- The Servo3 VCC and GND connect to the breadboard's VCC / GND inputs

- The Servo3 Signal connect to the Arduino Digital PWM 6

- The Servo4 VCC and GND connect to the breadboard's VCC / GND inputs

- The Servo4 Signal connect to the Arduino Digital PWM 9

- The Potentiometer's one outer pin connect to the breadboard VCC input

- The Potentiometer's other outer pin connect to the breadboard GND input

- The Potentiometer's middle pin connect to the Arduino Analog 1-2-3-4 input

Step 3: Code

I did not share the code because it is short and it varies according to the number of servo,potentiometer.

You can write code by watching the tutorial. This is a better way to learn.

I will continue to share long and complex codes.
