How to make a Solar Tracker using Arduino, Arduino solar Tracking system its circuit and programming

(Last Updated On: October 26, 2019)

Solar Tracker

Description:

In this tutorial, you will learn how to make your own Arduino based solar tracking system. This solar tracker project is based on the Arduino, LDR, and H-bridges. The LDR’s will be used for sunlight sensing. In this tutorial, I will discuss everything



  1. Complete circuit diagram
  2. Step by Step soldering
  3. Complete interfacing
  4. step by step controller program explanation
  5. Finally testing.

Today the solar trackers are used throughout the world, the solar tracker that we are going to make today is best as it’s cheap and is able to rotate heavy panels as we will be using the relays, and as you know relays can bear larger currents. We will be making our own H-bridge to control the direction of the dc Gear motor.
