A simple buzzer module to indicate e.g. errors with an Arduino. With this active buzzer one only has to offer a voltage, no frequency.
So put 5V on the buzzer, and it will beep! If you don’t have any pins (for noise) left over, this buzzer may also come in handy!
If you have an Arduino or other system/chip that can only supply a limited current, then you need a transistor for the control. The transistor is already present on this module, making it easy to use.
- Input voltage: 3.3V-5.5V (Vcc, GND)
- Power consumption: <25mA
- Frequency range: 2300 +/- 500Hz
- Digital input: I/O pin (low-active, so the buzzer switches on at a low/0V signal)
