Opto-Electronic Parts

These are opto-electronic parts - electronic components which use visible or infra-red light.  Most can be used as sensors on your robot - to detect lines on the RoboRugby table, to detect balls or to detect obstacles. 

Some are complete circuits, ready to use as sensors on your robot.  Others are components, which you can assemble to make your own sensors as you wish.  See instructions on building electronic circuits.
