Overview of this book

Scratch 2.0 is an easy to use programming language that allows you to animate stories and create interactive games. Scratch also gives you the capability of using programming to calculate complicated calculations for you. Scratch Cookbook will lead you through easy-to-follow recipes that give you everything you need to become a more advanced programmer. Scratch Cookbook will take you through the essential features of Scratch. You'll then work through simple recipes to gain an understanding of the more advanced features of Scratch. You will learn how to create animations using Scratch. Sensory board integration (getting input from the outside environment) will also be covered, along with using Scratch to solve complicated and tedious calculations for you. You'll also learn how to work through the exciting process of project remixing where you build on the work of others. Scratch Cookbook will give you everything you need to get started with building your own programs in Scratch that involve sounds, animations, and user interaction.
