Challenge 7

             This challenge was more complicated than the rest because it included variables and three different sensors.  It was definitely confusing but in the end it wasn't that  complicated. The objective is to keep going stop on a black line, then go again inside a box and stop in the middle, record the light sensor value inside and go backwards and show the recorded data. The first part wasn't  that hard it was when it included the variable it got messy. We had to try and try until Mr. Madali showed us most of the code. Over all it was the hardest thing we had done, it took some time but we got in the end, we were mostly there except we were just missing a few things that we needed clarification on.
