This is a simple Morse Code Transmitter I made for my Arduino Uno (Rev. 3).

It simply reads text strings from the serial port (USB cable), converts each character to its Morse Code equivalent, and beeps the code using a simple piezoelectric buzzer through a digital output pin.

  • @andersonle09 - Yes, it's a simple Piezoelectric buzzer. You put a voltage (3-20 volts DC) across the terminals, and it will beep.

  • does that buzzer make that sound when an electric current goes through it?
