Our first project. Windshield wipers are not very efficient. They don't get the full windshield clean! So that's why our first project is windshield wipers that clean the whole windshield.
The idea is the windshield wiper(s) will come from the bottom and the wiper(s) will go left to right to clean the entire windshield. When the process is completed the wiper(s) will fold down to where it came from.
