Scratch is a visual programming language that lets people of all ages unleash their creativity, no programming experience needed! You simply drag and snap blocks to create your program.

Here, we animate Scratch the Cat using a potentiometer hooked up to an ADC as an input. You could put together a video game controller and start hacking away at a game in minutes! With Scratch both the Raspberry Pi and the RPiSoC are immediately accessible to kids at any education level. Let us know what else you want to see with scratch.
