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

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
