The amazing versatile Arduino microprocessor board that can be used in many projects.
The Zumo Robot Shield can be fitted with a Reflectance Sensor Array that allows it to solve different line/maze style problems. The Zumo Shield libraries provide methods to help read values from the sensor array. Packages and installation instructions can be downloaded from GitHub and once installed the sensor library can be included from Sketch > Include Library. The sensor array uses the QTR sensors and therefore their library must also be included (installed as standard).
It is with mixed emotions that I purchased a Maplin N97DG Bluetooth Shield for the Arduino. I think its a good thing for Maplin and the Buildr community that Maplin are putting some high street umph behind Arduino and hobbyist electronics but I still reel at the whole mega corporations thing – can’t have everything I guess!
