Morse code keyer for Arduino.
I recently decided to build another project, this time involving morse code and the arduino.
I took a standard Arduino UNO, an LCD keypad shield, a relay module and a piezo buzzer. Total cost was under $25
What does it do?
Well it can send morse cq’s or any morse message to the onboard piezo or the relay for connection across a radio key. It has the ability to adjust the speed and timing of the morse. It demo’s the morse alphabet. You can decide it you want to use the relay or not. It can save the settings to the onboard EEPROM and keep them on power off.
