P2 Weekly Report for dplotnick:

Week 1
Task: Prepare the IR sensor array for use.

The line following robot uses a QTR-8A Reflectance Sensor Array available from Pololu Robotics and Electronics. The array consists of 8 IR LEDS and phototransistor pairs on a small printed circuit board. The line following robot requires two modifications to the array.


 * Only six of the eight sensor pairs are used. The circuit board has a provision to cut two pairs off the board.
 * A female pin header is needed to attach wires to the micro-controller.
