This is my first line-following robot. This is the parts list:


Arduino Uno

Adafruit motor shield

Pololu QTR-8RC line sensor. I used only 5 sensors.

Pololu 30:1 micro motor

7.2V (6 X AA NiMh batteries)



DVD case


Wire straps

3 screws and about a dozen nuts to act as raisers. Their screws length depends on height of your battery stack.



Arduino IDE 1.0

Adafruit motor shield library

Pololu QTR-8RC Arduino library
