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.

Arduino solar tracker with dc motor.

Copy this code and upload it to your arduino board. This solar tracker system uses the arduino uno board a servomotor 2 ldrs and 2 resistors to rotate the solar panel towards the sun or a source of light. Below is the program that will interface servo motor ldr with arduino for solar tracking. 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.

Can u give me some details. For designing arduino based solar tracker using ldr servo motor you need to program atmega 328 arduino microcontroller. It searches for the brightest light source like the sun. To track the sun i used four ldc sensors and arduino compares the data from them to rotate the panel in the direction with the most sunlight using two dc motors one for each axis and motor driver.

We used 2 solar panels of each 12v 150w which will bring the total to 300w. In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino. To switch between the two modes automatic and manual a push button is used. In this post i am going to talk about the solar tracker which i ve made using a arduino uno and sg90 servo.

Arduino solar tracker the proposed test bench is presented in fig. Here is the link to download the solar tracker code. The code essential measures the light intensity from both photo resistors it then compares the two to see which is receiving more light. Photovoltaic powers the solar tracker no external source needed.

I have to do this as mini project. 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. What is the rate and power of servo motor which u have used. And one voltage divider to get the voltage down to a voltage that the arduino its analog digital converter or adc can handle.

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. Try to power it within the recommended input voltage.
