Create blocks of data that represent values. Then map these blocks from a simple array.
Create hundreds of coloured rectangles.
In this activity you will create a rainbow in code using software sketchbook and a language “Processing”.
This post starts you off with Processing. Download, run and draw some coloured lines. The computer programming language Processing, is a great way to start coding. You get a quick visual result from a few lines of code.
