This project is a light gradient-sensitive robot with solar charging capabilities. In other words, it seeks out the light to charge itself. It accomplishes this behavior with four light-sensitive photoresistors in voltage divider circuits; the Arduino unit reads the four values corresponding to the intensity of the light received by the sensors through its analog read pins. It then applies a high voltage across a reed switch, which completes a circuit between a 9v battery and two toy motors, resulting in turning or moving towards the light.
