Exploring the Sound Sensor

The micro:bit with sound features a built-in
microphone sensor that can detect both loud
and soft sounds, as well as measure the noise

level around you. It can respond to sound in
different ways. The microphone sensor is placed
on the front of the board, along with an activity

LED that lights up whenever the microphone is
active.

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.
