Description
Our first two-axle solar tracker. The circuit can control two SG99R servomotors and thus align a solar cell for maximum solar irradiation.
Three photoresistors are used as sensors. The software runs on an ATmega 328P on which an Arduino bootloader was burned and can then be programmed via the Arduino IDE using an FTDI - USB adapter.
