Passive Buzzer 5V Module — PWM Tone Control, Arduino Compatible

Passive Buzzer 5V Module — PWM Tone Control, Arduino Compatible

A passive buzzer module that requires a PWM signal to produce sound — unlike active buzzers, the frequency of the PWM signal determines the pitch of the tone. This allows you to play melodies, musical notes, and variable-frequency tones using the Arduino tone() function. The go-to buzzer for Arduino music and sound effect projects.

Key Features

• ✅ Passive buzzer — PWM frequency control, play any tone or melody
• ✅ Arduino tone() compatible — use built-in tone() function directly
• ✅ 5V operating voltage — direct connection to Arduino 5V digital pins
• ✅ Variable pitch — frequency determines tone, from low bass to high treble
• ✅ 2.54mm header pins — breadboard and PCB compatible
• ✅ RoHS compliant

Typical Applications

• Arduino music and melody projects
• Sound effect generation for games and toys
• Variable-frequency alarm and notification tones
• DTMF tone generation and audio signaling
