OWI 9742 Comet

Pololu item #: 326

This product has been discontinued.

Comet is quick to respond and scurries speedily on command. A condenser microphone and a printed circuit board control this OWIKIT. Each time its sound sensor hears your command, it reacts; clap your hands or make any other loud sound to control it (and drop in a pen to make it draw!).
