Reflectance sensor for Zumo robot

Each emitter-receiver infrared pair of the reflectance sensor for Zumo robot sends a signal representing the amount of received light. A white floor will reflect lots of light while a black floor (or no floor) will reflect very few.

The four central sensors of the reflectance sensor for Zumo robot are close to each other to follow a line more precisely while the two external sensors are pushed to the sides of the board to see a line or an arena edge as soon as possible.

The reflectance sensor for Zumo robot can simply be plugged on the shield arduino for Zumo robot. It can be used at the same time as the sumo blade. It is not included in the robotics kit Zumo for Arduino.
