We added our own photosensors with series resistors, and an LED flashlight as a light source to make the mini-bot into a line follower. It would have probably been easier to get working if we had lowered the photosensors and added an LED light source for each sensor.
We had to use the dashboard port to find out what range of values we were getting out of each sensor (we had 3 sensors on the bot, but only actually used the outer two sensors), and we determined that each sensor had a different range of values, so we had to write code with that information in mind.
The actual code was pretty easy. The tweaking of sensor and motor speed values took a lot of experimentation.
