Arduino Solar Tracker With Dc Motor

So i ve made a solar tracker using an arduino and servo motor.

Arduino solar tracker with dc motor.

And one voltage divider to get the voltage down to a voltage that the arduino its analog digital converter or adc can handle. In this post i am going to talk about the solar tracker which i ve made using a arduino uno and sg90 servo. Copy this code and upload it to your arduino board. We used 2 solar panels of each 12v 150w which will bring the total to 300w.

It consists of only this components ldr module l293d motor driver module dc motor 30 rpm solar panel. The code essential measures the light intensity from both photo resistors it then compares the two to see which is receiving more light. I have to do this as mini project. For designing arduino based solar tracker using ldr servo motor you need to program atmega 328 arduino microcontroller.

Arduino solar tracker the proposed test bench is presented in fig. Below is the program that will interface servo motor ldr with arduino for solar tracking. Here is the link to download the solar tracker code. Can u give me some details.

It searches for the brightest light source like the sun. Before reading the post please check the video from my channel it gives 70 of idea about the project. 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. Photovoltaic powers the solar tracker no external source needed.

The energy monitor uses 2 current sensors to measure the current. 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. 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. To switch between the two modes automatic and manual a push button is used.

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. In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino.
