Detect Obstacles by Bumping into Them

Whisker sensors allow your ActivityBot 360° to detect obstacles by bumping into them.  When the robot's whisker bumps into an object, it makes an electrical connection between the whisker and a circuit on the breadboard.  In this lesson, you will program your robot’s Propeller microcontroller to detect those contacts and make the robot avoid obstacles.
