One problem with using a Raspberry Pi in school is that you are protected from evil-web-ness by the PxxxY. You see we cannnot even say the word without getting this page blocked too. This page explains how to set up your RPi so you can access the network and internet.
The Raspberry Pi is the infamous credit card sized computer that has revitalised the computer based experiementation first seen with the BBC Micro in the 1980s. It runs a special flavour of Linux called Raspbian, which encourages students to explore the inner workings of a modern operating system. The Pi comes with GPIO (General Purpose Input/Output) pins that allow it to be connected to external devices ranging from LEDs and motors to temperature and movement sensors. There many things that you can do with a Raspberry Pi including:
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).
