Download Buzzer / Application / LibreConnect / Source
Play music / Build an alarm using a buzzer.
Applications
Midi Keyboard
- Plug your MIDI keyboard.
- Go to http://madnerd.org/interface/midi
Midi Software
You can compose music that will be played by the buzzer.
LoopMidi
We are going to use loopMidi to generate virtual midi port on Windows.
- Download : loopMidi
- Click on + to create a virtual midi port
LMMS
Examples are available in lmms/
- Download LMMS : https://lmms.io/download/#windows
- On TripleOscillator put the volume to 0
- Click on the gear next to TripleOscillator
- Click on Midi and choose your virtual midi port (Loopmidi by default) ##
Commands

Build buzzer
Components
- Arduino nano CH340G: 2€
- 10 Buzzer : 1.80€ (1 Buzzer:0.18€)
- Resistor pack 400pcs (3€) (1 resistor: 0.0071€)
- 5 pcs stripboard (1.18€) (1 stripboard : 0.24€ )
- Total : 7.98€ (2.43€)
Wiring
Don’t forget to isolate the circuit from the arduino
Buzzer only
- Pin 9 : RESISTOR (100Ω) — Buzzer +
- Pin 10 : Buzzer -
Buzzer/Led
You can add a led (before the resistor)
- Pin 9 : RESISTOR (100Ω) — Led + / Buzzer +
- Pin 10 : Led - / Buzzer -
3D Printing
This model is a all purpose case for arduino nano projects
