Raspberry Pi. Best projects

Take advantage of the huge potential of a miniature computer!

Raspberry Pi is a real computer with the size of a slightly overdone credit card. It has huge potential, quite a lot of computing power, and it costs very little. This platform was designed with the idea of learning programming for children. However, as often happens, the story has gone completely different. Currently, Raspberry Pi is used as a web server, movie player or device driver. Do you have a good idea to use Pi in the project? Or maybe you do not know what you would like to do with Raspberry Pi?

This book will dispel all your doubts and suggest ideas for attractive projects. During the reading you will learn about the construction of Raspberry Pi and you will learn how to connect it and run the Linux system. In the following chapters you will prepare a game of a cross and a cross and create your own teleprompter. If you need an electronic clock to measure your reaction time or dream about a twittdling toy, then you are holding the right book! If you want to live in a smart home for reasonable money - you will be interested in the chapter devoted to its automation. Check how easy it is! It is a must-read for all enthusiasts who want to squeeze the seventh sweat out of Raspberry Pi!

Reach for this book and:

• explore the construction and basics of using Raspberry Pi
• generate a maze in Minecraft
• build disco lights
• prepare your own motion sensor
• Make your electronic dreams come true

A collection of the best projects for Pi!
