First, draw some arrows and buttons for ‘pen up/down’, ‘colour change’, ‘bigger’ and ‘smaller’ in a very soft pencil on some paper. Draw tracks and wire up the arrows to the cursor keys on the Makey Makey. Pen up/down goes to the spacebar, colour change is S, bigger is W and smaller goes to key A. If you don’t have a Makey Makey, you can still use keys on your computer’s keyboard.
The code for Scratch-a-Sketch is here – you can play online in the Flash version if you like, you don’t even need Scratch installed.
Unlike a traditional Etch-a-Sketch, you can lift the pen up to move around without drawing, change colour and pen size, and combine keys such as 2 arrow keys to draw decent diagonal lines.
