The purpose of this project is to use two light sensors (photoresistors) to measure light intensity in two opposite positions (0 & 180°) and indicate the position with a servomotor. The materials that will be used are two light sensors, one Arduino micro-controller, two LEDs, and one servo motor. Each LED will indicate when a photoresistor is illuminated (positioned on opposite sides of the servomotor), while the servomotor moves to the illuminated side. In addition, when the intensity of the two photoresistors is almost the same, the servo motor must be placed in a central position (90°), and both LEDs must be turned off. Also, a buzzer must be turned on to indicate this condition (90°).
