LED-Following Car
Engineering week '15' in University of Khartoum For this project, we made a car that follows a path made by a LED strip. We used two LDRs to detect the lights from the LED while considering ambient light. The voltage generated by the LDRs were sent to an A-to-D converter in microcontroller so that we could calculate the car’s relative position compared to the LED strip and decide when to turn in software. We then controlled the car by sending the appropriate signals to the motors.
