RPi Mainx250You can do many things with the Raspberry Pi, and some have built a Star Trek interface, while others have automated their house. This book provides the building block to work with Xojo to react with the real world through its motherboard to allow you to make your own interesting device. This inexpensive computer can be programed by the widely recognized Xojo programming language. 

This book “I Wish I Knew How to … Program Raspberry Pi 2 B and Raspberry Pi 3 B Electronics with Xojo” goes into the numerous programs that can be built to interact with many types of electronic gadgets.

The ‘I Wish I Knew’ series contains technical data and advice that makes sense and contains practical and numerous examples with explanations to allow you to ease into the steep programming curve. There are many electronic examples and the book also has many references to the Jessie Linux Operating System that is used with the Raspberry Pi. 

You can start building your own electronic projects with Raspberry Pi today!

Click to download the Raspberry Pi Table of Contents, which has a listing of all of the examples in the book, many of the terms, and commands used in the operating system. 

There are over 22 chapters with more than 450 pages with over 60 example programs. 

Examples include Ultrasonic distance, LCD words, graphics, and custom glyphs, infrared sensors, photo and video recording, servos, LEDs, infrared receivers, and more. Many screenshots have been added to show the results of the code with a full index to help find topics quickly. Examples include a circuit diagram or breakout board diagram to help with wiring the components on the Raspberry Pi. The book is in PDF format with example chapter folders containing Xojo source code and running examples.

It is assumed that you have an intermediate understanding of both electronics and programming of the Xojo language. 

This ebook is a pdf formatted document and all examples include Xojo code. This is one of many books which can be purchased at Xojo Library.

Note: A license is required to build the programs for Xojo - the demo version does not build programs.
