Discover how to use the new micro:bit's built-in microphone to control your programs and measure sounds around you
The new 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.
The microphone is on the back of the new micro:bit, and on the front you'll find a new microphone LED next to the hole that lets the sound in. It lights up to show you when your micro:bit is measuring sound levels.
