Getting Started with the micro:bit book review

Goal of this book is to deliver a practical introductory guide to microcontrollers, how they work and how to extend their functionality using electronic circuits and code.

The educational theme is accentuated by:
• easy-to-follow step-by-step instructions
• full colour images and diagrams
• fully explained code examples - with coloured syntax
• electronic circuit diagrams
• electronics theory plus example calculations
• topic-specific ‘Going Further’ challenges
• end-of-chapter quizzes (with end-of-book answers)

The first chapter is a basic introduction into the microbit board, its component, control capabilities and interfacing to external devices.

While chapter two introduces basic coding techniques using the popular web-based Microsoft block editor.

The next three chapters offer more advanced coding examples, including controlling the LED display, A and B button interaction, creating programs with loops and decision logic.

The remaining chapters dig a little deeper into digital and analog I/O, with real-world project examples such as detecting battery level, temperature and movement.

webOS for Raspberry Pi 3B

The open source webOS operating system – originally developed by Palm - has been optimised to run on the Raspberry Pi, as hosted at webosose.org.

Viper is hosting a pre-built image for download. Alternatively you can use an Ubuntu 14.04 LTS 64-bit distro and compile the source code yourself.

The recommended Pi platform is the Raspberry Pi 3B, or the new Pi 3B+. The initial offering only offers a small number of apps, but developers can create their own with the IoTivity and iotivity-node node tools.
