“Fun and easy green robot! Build a sun tracking solar array in under an hour. Bonus: charge your phone with free clean energy!
Going Green
I have been working in the renewable energy industry in Australia and tinkering with Arduinos for some time now, but its not until this project that I finally decided to combine the two and build my own small solar device. One small note up front, this project obviously requires 5V to power the Arduino and servo, which are used to maximise the output of solar panels that at best at produce 3.4V. So its not exactly paying itself off. However the concept is scalable, so if, for example, you used this concept on an array of 8 panels, producing 12V, well then you could power the arduino and charge your phone without an external power source. I plan to do this one day, and will add a link here when it happens.”
