Arduino Solar Tracker With Dc Motor

If the difference is greater than a small threshold then the arduino tells the servo to move in that direction to direct the panel towards the light source.

Arduino solar tracker with dc motor.

Before reading the post please check the video from my channel it gives 70 of idea about the project. Can u give me some details. And one voltage divider to get the voltage down to a voltage that the arduino its analog digital converter or adc can handle. Arduino solar tracker the proposed test bench is presented in fig.

In this post i am going to talk about the solar tracker which i ve made using a arduino uno and sg90 servo. Below is the program that will interface servo motor ldr with arduino for solar tracking. For designing arduino based solar tracker using ldr servo motor you need to program atmega 328 arduino microcontroller. I have to do this as mini project.

To switch between the two modes automatic and manual a push button is used. The code essential measures the light intensity from both photo resistors it then compares the two to see which is receiving more light. It searches for the brightest light source like the sun. Arduino recommended input voltage is from 7 to 12 volts but you can power it within the range of 6 to 20 volts which is the limit.

It consists of only this components ldr module l293d motor driver module dc motor 30 rpm solar panel. We used 2 solar panels of each 12v 150w which will bring the total to 300w. So i ve made a solar tracker using an arduino and servo motor. It is based on a solar tracker that can rotate automatically to track the sun with the help of four ldr sensors and two servomotors sm1 and sm2 or manually using a potentiometer.

The energy monitor uses 2 current sensors to measure the current. Here is the link to download the solar tracker code. What is the rate and power of servo motor which u have used. Copy this code and upload it to your arduino board.

Photovoltaic powers the solar tracker no external source needed. Try to power it within the recommended input voltage.
