Arduino - 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. In the next tutorial, I'll show you how to use multiple servos with potentiometers.

Step 1: Hardware Required

- Arduino Board

- Servo Motor 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 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

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

Middle pin is signal pin

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

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

- Potentiometer's middle pin connect to the Arduino Analog 1 input

Step 3: Code

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.
