that show order numbers. These displays help
customers know when their food is ready. When

an order is placed, the restaurant staff updates
the number on the display. Once the order is

prepared, the number flashes on the screen,
notifying the customer. This application makes
the process efficient, ensuring customers are

served in the correct order without confusion.

How Sound Sensors Work?

The micro:bit with sound has a built-in
microphone sensor. It can react to loud and

quiet sounds, and also measure how loud
your environment is.

It can be used to respond to sound. The

microphone input sensor is located on the
front of the board alongside a microphone
activity LED, which is lit when the microphone is in use.

• When the microphone detects a loud sound, like a clap, it shows a large

heart on the LED display.
• If it detects a quiet sound, for example after your clap has finished, it shows

a small heart.
• The effect of this is to create a simple heart animation

that responds to claps or strong beats in music.
