Circuit solar tracker project

Circuit Diagram
The circuit design of solar tracker is simple but setting up the system must be done carefully.
Four LDRs and Four 100KΩ resistors are connected in a voltage divider fashion and the output is given to 4 Analog input pins of Arduino.
The PWM inputs of two servos are given from digital pins 9 and 10 of Arduino.
