Parking Assist Stop Light

This is a project that I adapted from a project I saw on the Arduino forums. It uses and ultrasonic sensor to detect the car and measure the distance. It has a rotary encoder so you can change the stop distance to whatever distance you want. I have uploaded the code wiring diagram and readme to my github and I will put the link to it here: https://github.com/Captainfructose/ParkingAssistStopLight
