Challenge 3 (Line Follower)

 This challenge was harder than the first two because we actually had to do it on our own. The final code came out to be pretty simple but it was still hard. The beginning of starting the challenge we made so many mistakes and trials. The main objective  is to make the robot follow the black line and also let turn as the line turns. In the end after trying out different codes, somebody got it and we got some help. In the end we finished and I hope I got a good grade.
