Story

This device is set up so that the LED's are off until it detects an object (car) at 140cm, then when it gets closer, more LED's come on until all them are lit at 40cm.

Once the car reaches 30cm all the LED's turn off, this signals that you have reached the correct parking distance from the wall.
