Line Follower Robot with Obstacle Detection

This is part of a school project for Projects I class. It's basically a black line follower robot that is capable of stopping in front of an obstacle or reaching the end of the route (symbolized by when both line sensors detect a black line). The vehicle can listen to a command received by the serial to start or stop the route.

The full project consists of controlling this vehicle based on traffic light status that will be detected using an Android smartphone in a controlled testing environment. I'm fixing some stuff before uploading the other part of the project on to GitHub, but when I do, I'll post the link here.
