MEET THE BIT
o6 BUZZER
The buzzer makes a sound no one can ignore. It's great at
sounding the alarm or annoying those nearby.
The buzzer converts the
electrical signal it receives
into a vibration, which
creates a buzzing sound.
The higher the signal it
receives, the more intense
the vibration, and the
louder the sound is.
