Arduino Tutorial – Multiple Servo Control with Arduino

In this tutorial, we will learn how to use multi-servo with Arduino. We will control 4 servo motors with Arduino PWM outputs.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’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 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
