You should use IR pair as sensor. Either 3 pairs or 5 pairs have to be used for good accuracy.

Looking at speed of motor, I will suggest you to use 5 pairs.

The code........
it depends upon the design & position of the sensor. Please let us know what is the design of the bot & position of the sensor
