Do I need to buy hardware for this tutorial?

No. Everything runs in the browser: Circuitly simulates the board, the components and the code. Real hardware is optional if you want to rebuild the circuit afterwards.

Which components are used?

Arduino UNO board, Piezo buzzer. They are already available in the simulator library.

How long does it take?

About 20 minutes, advanced level, in 3 guided steps.

What should I know before starting?

The previous tutorial in the series, “Buzzer: playing notes”, is enough preparation. No software install is required.

Is the code provided and checked?

The simulator checks your wiring and your code automatically at every step, and shows the commented solution if you get stuck.
