Active Piezo Buzzer

This active buzzer can be connected to a digital Arduino output and emits a fixed tone of around 2500 Hz when voltage is applied. It is often used to signal a key press or a confirmation.

Recommended alternative for your own pitches, passive: Piezo Buzzer Passive with Connection Cable

Features:

• Active: fixed tone as soon as voltage is applied
• Long pin: positive, short pin: GND
• Can also be operated at 3.3 V: first check that the output can supply 15 mA, do not connect directly to an ESP8266
• Remove any protective seal "Remove seal after washing" from the opening before use

Application Examples:

• Signalling a key press or a confirmation
• Alarms and notifications in Arduino projects
