infrared (IR) tracking system(Mini Project)

Our project is an infrared (IR) tracking system. A beacon, placed on the object to be tracked, continuously emits infrared signals in all directions. The signals coming from the beacon are detected by 2 IR receivers mounted on 2 stepper motors, which rotate independently and are in separate locations. The direction each receiver is pointing towards allows the CPU to determine the position of the beacon via triangulation. The position of the tracked object is then displayed on the TV, where the center point is the middle point of the 2 receivers, and the distance and direction are displayed on the LCD.
