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. Photovoltaic powers the solar tracker no external source needed. Arduino solar tracker the proposed test bench is presented in fig. For designing arduino based solar tracker using ldr servo motor you need to program atmega 328 arduino microcontroller.

In this post i am going to talk about the solar tracker which i ve made using a arduino uno and sg90 servo. 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 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.

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. The code essential measures the light intensity from both photo resistors it then compares the two to see which is receiving more light. It consists of only this components ldr module l293d motor driver module dc motor 30 rpm solar panel. It searches for the brightest light source like the sun.

Try to power it within the recommended input voltage. 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. Before reading the post please check the video from my channel it gives 70 of idea about the project. To switch between the two modes automatic and manual a push button is used.

Below is the program that will interface servo motor ldr with arduino for solar tracking. Can u give me some details. What is the rate and power of servo motor which u have used. We used 2 solar panels of each 12v 150w which will bring the total to 300w.

I have to do this as mini project. In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino.
