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