All of the computing work is done by an Arduino UNO as mentioned in the video. The components and parts used for this project are: An Arduino UNO microcontroller board A 16x2 LCD display A micro servo 2 IR proximity sensors(to detect the cars going in and coming out) 2 10k ohm resistors( as pull-down resistors for sensor's digital output) A 10k ohm potentiometer(accurately, a preset to change the LCD display's contrast) Some wires A DC power supply(5-12 volts)
