Arduino solar tracker the proposed test bench is presented in fig.
Arduino solar tracker with dc motor.
Below is the program that will interface servo motor ldr with arduino for solar tracking.
Before reading the post please check the video from my channel it gives 70 of idea about the project.
Photovoltaic powers the solar tracker no external source needed.
Try to power it within the recommended input voltage.
And one voltage divider to get the voltage down to a voltage that the arduino its analog digital converter or adc can handle.
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.
Copy this code and upload it to your arduino board.
Can u give me some details.
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.
To switch between the two modes automatic and manual a push button is used.
In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino.
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.
For designing arduino based solar tracker using ldr servo motor you need to program atmega 328 arduino microcontroller.
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.
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.
What is the rate and power of servo motor which u have used.
In this post i am going to talk about the solar tracker which i ve made using a arduino uno and sg90 servo.
It consists of only this components ldr module l293d motor driver module dc motor 30 rpm solar panel.
So i ve made a solar tracker using an arduino and servo motor.
I have to do this as mini project.
Here is the link to download the solar tracker code.
