Full Tutorial

This tutorial will show you how to control servo motor using Arduino Nano and an easy to use Servo motor driver.

Servo motor is one of the most widely used actuators in the field of science and robotics. They used in a large number of applications which are critical in position control. We cannot use DC motor to control a tail of aircraft because controlling a DC motor for accurate positioning is not only difficult but almost impossible.

The PCA9685 is a 16 Channel 12 Bit PWM I2C-bus controlled Servo motor Driver. The Driver can very easily connected to your arduino, Raspberry Pie and easily programmed to control single or multiple servo motors and make your own RC plane, car, ship, quadrapod, hexapod or anything you want.

Components Required

Arduino Nano

Or any arduino board which will be the controlling centre of our project

Voltage Regulator Module

For providing controlled and stable DC source for the working of servo motors as well as internal chips.

PCA9685 16 Channel 12 Bit PWM I2C-bus controlled Servo motor Driver

The PCA9685 is a 16 Channel 12 Bit PWM I2C-bus controlled Servo motor Driver. The Driver can very easily connected to your Arduino, Raspberry Pie and easily programmed to control single or multiple servo motors and make your own RC plane, car, ship, quadrapod, hexapod or anything you want.

Servo Motor

Servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration. It consists of a suitable motor coupled to a sensor for position feedback.

Design your own PCBs for your Project!

I used Altium designer to draw the circuit and design the PCB. It is a powerful tool that can be used to design and create our own PCBs for our project as well as complex and multi-layer PCBs for industrial use.


If you are a DIY Electronic enthusiast, I bet this is gonna be really useful for you guys. I have been using it for the past 3-4 years and let me tell you guys, this is amazing! You can download the Free Trial of Altium PCB Designer from here.
