<Please Enter Name> <Please Enter University> A light tracking system was created to search for the brightest spot in the room and display its location from a reference point on a liquid crystal display (LCD). The system comprised a microcontroller, servo motor, two phototransistors, a universal asynchronous receiver/transmitter (UART), an LM358 operational amplifier, battery and battery holder, LCD, and associated wiring.
Methods
The microcontroller was programmed to direct the servo motor to search the room within 180 degrees, and to continue in search mode, until the brightest light was detected by the phototransistors within two feet of the ...
