Strings and Arithmetic Operations

This guide, for more advanced users of LINUX, shows how BASH scripts can be used for operations on strings and for arithmetical operations. The syntax for BASH is clearly explained.

BASH Basics

This introductory guide explains how to use the LINUX shell known as BASH (Bourne Again Shell). BASH is useful for linking together various programs for creating innovative solutions, and can unleash the power of a Raspberry Pi.

The guide covers running BASH, the syntax used, how to chain together commands,...

Embedding Text and Programs

This intermediate-level guide shows how BASH scripts can be used to handle files and to integrate other programming languages such as Perl. String manipulation features heavily in the exercises. A challenge is set to use a Python program along with a shell script.

Building Bots with LEGO

The BrickPi is an interface between the Raspberry Pi and LEGO Mindstorms or EV3 sensors and motors, a portable power source for the Raspberry Pi, and a case that allows you to attach LEGO motors, beams, sensors, and other parts.

This resource includes guidance on setting up and programming the Raspberry Pi...

Scratch Interface

This guide shows how the BrickPi can enable novice programmers to use Scratch to control complex robots and models.

The instructions need to be followed using Scratch on the Raspberry Pi computer. The resulting programs use different input and output devices, including touch and colour sensors and motors....
