Arduino & Lego Solar Tracker (biaxial)
I made a solar tracker with lego and arduino.
This is a very nice and simple project, if you want to learn arduino and electronics. No welding required.
Its purpose is only educational because the engines are not strong enough to support the weight of the solar panels.
It’s always a cool solar tracker, I learned the Arduino and had a lot of fun.
