ScratchPaper is a mash-up activity that lets us explore ideas around circuits, arduino, and visual programming. Often we've seen programming and arduino workshops that look complicated and not so inviting to novice participants. For this workshop, we built fun and colorful example paper cards with single gumdrop LEDs, pre-made switches and sensors, and RGB lights to communicate a playful attitude.
We've found that this addition of whimsical elements as well as a combination of high and low tech materials can give a more open invitation to join in the exploration of computational tinkering. We use ScratchX, an experimental extension to the Scratch programming language that adds blocks to allow you to control an arduino mounted on a wooden block.
