Lilypad Personalised Alert Buzzer

In this lesson students will create a personalised musical buzzer by programming the LilyPad Arduino to play a sound using the Main board, Buzzer and Button, coding the note frequency in Arduino IDE. The lesson can be extended to include LED’s that light up or flash according to the note played to enable the buzzer to be used for the hearing impaired. This lesson idea was created by Toni Falusi.
