Scratch Programming in Easy Steps introduces readers to Scratch, a programming language that is widely used on the Raspberry Pi. Using Scratch’s highly visual interface, you'll learn how to make games and animations. Along the way, you’ll learn about some important ideas that underpin most programming languages. The book includes examples of games and techniques that readers are invited to customize and build on to make their own programs, and begins with a foreword by Mitchel Resnick, Professor of Learning Research at the MIT Media Lab, which created Scratch.Scratch makes it easy to create your own games, animations, music, art or applications. It's the perfect way to learn programming because it takes away a lot of the complexity. That means you can focus on having great ideas and bringing them to life.This book is an in-depth guide to both the new web-based Scratch 2.0, and Scratch 1.4, as used on the Raspberry Pi. With no prior knowledge needed, this book takes you from scratch to Scratcher! - from Amzon
