This reflectance sensor module is designed specifically for use with the Balboa 32U4 balancing robot. It features five IR LED/phototransistor pairs that are great for identifying changes in reflectance on the ground directly underneath the Balboa (like detecting or following a black line on a white background). The sensor array offers dimmable brightness control, and each sensor provides an independent output that can be measured with a digital I/O.
