This is a dream of every student to make something new and interesting so today I am going to teach you that how to make Arduino-based solar tracker. Everyone knows that solar panel output voltage level depends upon on sunlight efficiency if more light photons striking on solar panel it will produce more voltage with maximum efficiency but we don’t know if we fixed and install the solar panel in some
constant position then for some time it will receive strong light but due to change in time sun changing their position and the solar panel not receiving enough light because due to mismatch of their line of sight between sun and solar panel.
Here we used Arduino UNO R3 to make it possible to track the movement of the sun and get the full efficiency from our solar panels.
* 4 Resistor,s of 100k
