Hello and welcome to part 8 of the Raspberry Pi tutorial series. In this tutorial, we're going to put together what we've learned so far to create a garage stop-light.
The idea of a garage stop-light is to show green when you have plenty of room to pull your car forward in your garage, and then turn yellow as you approach the fully forward position, and then red when you should stop. We're going to build this system with our Raspberry Pi, and use some distances that we can easily test.
