5V Active Buzzer Module for Arduino (Alarm/Beep) | KY-012
The loudest and easiest way to add sound to your project. This Active Buzzer module creates a loud beep as soon as you give it power. Unlike "Passive" buzzers that need complex code to make sound, this one is simple: High = Beep, Low = Silent.
-
Type: Active (Internal Oscillator).
-
Voltage: 3.3V - 5V DC.
-
Sound: Loud continuous tone (approx 2.5kHz).
-
Best For: Alarms, Timers, and Button Feedback.
