Output

When the program runs, the
Micro:bit plays the ringtone sound
continuously through the buzzer.

At the same time, the LED display
keeps changing between two icons
every second. This shows how the

Micro:bit can control output devices
like buzzers and LEDs together
to make interactive and creative

projects.

You can also add more blocks to
make the ringtone play a set number

of times or trigger it when a button is pressed, depending on your preference.
