Challenge 4 (Wall Detection)

 This challenge is very similar to challenge 2 and it was easy because it was also guided practice. It was definitely interesting to see another sensor on the robot work. The whole challenge is pretty much about letting the robot go forward but then as it senses something in front it would back up and rotate. It was a fairly easy project. This time me and partner switch up and she was the one to put in the code. Over all it was a good challenge. We understood why the codes were there and hopefully we know how to use them for following projects.
