Meet the Protractor: a proximity sensor that measures angles and can make your robot smarter. It can tell you nearby objects as well as open pathways thanks to its 180 degree field of view. With the Protractor, you will be able to program your robot to run mazes or obstacle courses.
The Protractor consists of an active IR sensor to measure the amount of light that bounces of nearby objects. It outputs angles when requested by a microcontroller.
