Volcano Event Lab
You're the Volcano Engineer! An EVENT is like a tripwire — when something happens (a tap, a timer, heat rising), your program LISTENS and does something in response. Wire triggers to actions and make the volcano come alive!

⚡ Today's Concept: Events

An event is something that happens — like a button being tapped, a timer going off, or heat rising. Your program can listen for events and respond automatically. It's like setting up a tripwire: when someone walks into the string → an alarm rings! You don't check constantly — you just listen and react.

🔍 Listen — watch for something to happen ⚡ Trigger — the event that starts it 🎬 Action — what happens in response
← Last time you packaged steps into reusable FUNCTIONS. Today you'll wire LISTENERS that respond when events fire!
Step 1 / 4
First Eruption! Wire the 🔴 Button trigger to the 🌋 Erupt action. Then tap FIRE on the Button trigger to see the volcano blow!

💫 What You Learned

  • An event is something that happens — like a button tap, a timer, or heat rising.
  • Your program can listen for events and respond automatically — no checking needed!
  • A trigger is the event that starts things. An action is what runs when it fires.
  • You can wire multiple triggers to different actions — each event has its own response.
  • Event-driven code is how apps, games, and websites respond to taps, clicks, and timers!
🎬 Come Back Tomorrow!
Next up: combine events with data collections to build your own Alarm System that tracks multiple signals at once!
