Arduino Solar Tracker With Dc 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.

Arduino solar tracker with dc motor.

It searches for the brightest light source like the sun. We used 2 solar panels of each 12v 150w which will bring the total to 300w. In this post i am going to talk about the solar tracker which i ve made using a arduino uno and sg90 servo. I have to do this as mini project.

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. For designing arduino based solar tracker using ldr servo motor you need to program atmega 328 arduino microcontroller. It consists of only this components ldr module l293d motor driver module dc motor 30 rpm solar panel.

Before reading the post please check the video from my channel it gives 70 of idea about the project. In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino. Photovoltaic powers the solar tracker no external source needed. What is the rate and power of servo motor which u have used.

Arduino solar tracker the proposed test bench is presented in fig. And one voltage divider to get the voltage down to a voltage that the arduino its analog digital converter or adc can handle. 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. To switch between the two modes automatic and manual a push button is used.

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. So i ve made a solar tracker using an arduino and servo motor. Try to power it within the recommended input voltage. The energy monitor uses 2 current sensors to measure the current.

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 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.
