Story

Concept, Build, and Demonstration Video

I am finally able to park in a garage, which takes some getting used to. I like to have as much space as possible to access the workbench along the back wall, but trying to get as close to the garage door has caused some...problems.

This device senses the distance of the object in front of it (a vehicle) and depending on range, one of three lights will turn on.

Red light location can be adjusted by rotary encoder.

Red light location can be adjusted by rotary encoder.

Red light location can be adjusted by rotary encoder.

Green = Keep Driving

Yellow = Approaching Stopping Point

Red = Stop!

The Stopping point can be adjusted via a rotary encoder on the side of the device, current range and the set stopping distance can be observed on the OLED display.

The Red light the variable that can be adjusted, and the ranges of the yellow and green lights are based on that variable.
