Solar Panel Tracker Arduino

Arduino nano and shield is easy way to connect servo motors and photodiodes i used photodiodes but now i think i should have used ldr instead of photodiodes.

Solar panel tracker arduino.

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 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. Pin de la fotoresistencia left int ldrr 2. This solar tracker control system is designed to take light measurements from the east and west left and right side of the solar panel and determine which way to move the panel to point it directly at the source of the light.

The circuit design of solar tracker is simple but setting up the system must be done carefully. In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino. Hi thank you very much for the idea. Four ldrs and four 100kω resistors are connected in a voltage divider fashion and the output is given to 4 analog input pins of arduino.

Se nombra el servo horizontal int ldrl 1. Try to power it within the recommended input voltage. The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. Pin de la fotoresistencia right int delaypot 4.

Solar panels are green energy source such as wind tribunes. To switch between the two modes automatic and manual a push button is used. I adapt it for 2 ldr. Según el montaje se puede modificar must be modified according to the assembly include include la libreria servo h servo horizontal.

Arduino solar tracker the proposed test bench is presented in fig.
