In session 3, now that your robot is completely assembled and wired up, its time to get it moving. You will start with getting to just move forward in a straight line without incorporating the sensor, then experiment around with changing the pin values to make it execute different maneuvers.

In session 4, you will implement the sensor to be able to read the difference between black and white/reflective surfaces. It will display the sensor number on the serial monitor if it is sensing nothing or if it is sensing a black surface.

Session 5-Following a Line

In session 5, you will get the IR sensor and the motors to work together in a program that follows a line and then stops when it doesn't sense a line to follow anymore. This program also implements some small corrections for slight veering.

Session 6-Maze Navigation
