DIY Home Security – New Video: https://youtu.be/UBNpL5WpJ54

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.

In the next tutorial, I’ll show you how to use multiple servos with potentiometers. Do not forget to subscribe. Thank you for your support.

I did not share the code because it is short and it varies according to the number of servos. You can write code by watching the tutorial. This is a better way to learn. I will continue to share long and complex codes.

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 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
