It’s fun to see how different people use the same hardware, and Jan Muller has come up with a really interesting visualisation for his PING range finder. With an Arduino controlling the servo the ultrasonic range finder is swept around the room measuring the distance to the objects around it. The readings at each servo step are transmitted via a serial link to his laptop where a Processing application visualises the angle and distance in a Radar-like screen. Great stuff.
