Press, Click, Go! — How Events Make Code Run
For grown-ups
Companion summary
Have you ever wondered what happens inside a computer the moment you press a key? Events are how apps and games know when to spring into action — just like a doorbell ringing when someone arrives. Every tap, click, or keypress sends a tiny signal that triggers code to run. When you finish, try making a sprite in Scratch move only when you press a specific key.

What Makes Things Happen?
Think about a light switch. Nothing happens until you flick it — then the light turns on. Your flick is what starts everything. In coding, something very similar happens. Programs do not just run on their own. They wait for something to start them. Can you think of three things you do on a computer or tablet that make something happen? Maybe you tap a button, or press a key, or move the mouse.
