The Buzzer Small – 5V Piezo Beeper generates audible tones and alerts when driven by DC voltage or PWM signals. This small 5V active/passive buzzer is ideal for alarm systems, notification sounds, and audible feedback in projects.
Key features
- 5V operation
- Piezoelectric element
- Compact size
- Low current consumption
- Audible frequency range
- Easy interfacing with microcontroller
- Through-hole mounting
Good to know
- Verify active vs passive type – active has built-in oscillator
- Passive buzzer needs PWM for tone generation
- Active buzzer beeps with DC voltage only
- Use tone() function on Arduino for passive buzzers
- Current draw spikes at resonance frequency
