Schematic of the Arduino Solar Tracker Circuit. As you can see in the schematic all that you need to make the electrical part is the board, one servo, 2 LDRs and 2 x 10K resistors. Usually the servo ...

The sketch first calls on the Servo library and then defines the two servos as tilt and pan. The joystick x-axis is attached to Arduino pin A0 and the y-axis to Arduino A1, and these are our INPUT.
