Arduino Tutorial – Multiple Servo Control with a Potentiometer

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.

 

Connections:
The external battery VCC / GND connect to the breadboard.
The Arduino GND connect to the breadboard 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 other pins are power (VCC) and ground (GND)
Middle pin is signal pin

 

The Servo 1 VCC and GND connect to the breadboard VCC / GND inputs
The Servo 1 Signal connect to the Arduino Digital PWM 3
The Servo 2 VCC and GND connect to the breadboard VCC / GND inputs
The Servo 2 Signal connect to the Arduino Digital PWM 5
The Servo 3 VCC and GND connect to the breadboard VCC / GND inputs
The Servo 3 Signal connect to the Arduino Digital PWM 6
The Servo 4 VCC and GND connect to the breadboard VCC / GND inputs
The Servo 4 Signal connect to the Arduino Digital PWM 9

 

The Potentiometer one outer pin connect to the breadboard VCC input
The Potentiometer other outer pin connect to the breadboard GND input
The Potentiometer middle pin connect to the Arduino Analog 1-2-3-4 input
