Scratch is what is called a “visual” programming language that was created at MIT in 2007 to make it easier for children to learn how to progam in schools.

It was written in a language called Squeak which is a version of Smalltalk and actionscript and Javascript.

You open the software on your screen and you see a collection of inch long colored blocks that represent motors and sensors etc that you join to each other and adjust the numbers on them to have them do actions.

By putting them in the correct order you are on your way to basic programming.

This is what it looks like if you program other toys like the Meccanaoid by Meccano or the Mindstorms products by Lego.

A company called Dexter Industries sells some amazing robotics kits for schools and everyone else and has some excellent free training information on the site for programming in Scratch, Python and other languages.
