Hi guys. I want to show you my solar tracking system project. The system can move along two different axis. I used 4 LDR light sensor for sensing light and 2 servo motor for giving positions according to values read from sensor. 4 sensor are grouped as 2 sensor couple. The analog signals taken from LDR sensors are converted to digital signal with using MSP430G2553. Each sensor couple values are compared independently and give direction one servo motor.
