This activity helps children to understand the components of computer systems, with a focus on input devices. It links this to their everyday experience, by comparing games controllers, keyboards, microphones and other everyday peripheral devices. The practical part of the activity involves creating programs in Scratch that accept user input via a keyboard, triggering some sort of output. They then go on to create code to handle events involving other input devices. They are then encouraged to share what they have learned through presentations and peer teaching. A range of sample Scratch programs are provided, using different inputs including Lego WeDo sensors, Picoboards, Makey Makey, microphones and so on.
