The Infrared Line Follower Kit from Parallax provides eight infrared emitter and receiver pairs for high-precision line-following applications. Mounting hardware for both the Boe-Bot and Stingray are also included for easy startup.

All IR frequency generation is done onboard using an ICM7555 chip, requiring no external signaling. This allows for simple interfacing to the Infrared Line Follower, since the user only needs to read the state of each IR receiver to detect white or black surfaces. An “Enable” pin is also included which when pulled low puts the Infrared Line Follower into low-power mode.
