This Arduino project reads Morse code input from a button and displays the decoded letters on a 4-digit 7-segment display. It measures how long the button is pressed to distinguish dots (.) and dashes ...

The code will take input from pin 8 as the clock signal and pin 9 as the push button. It will transmit data through pins A4 and A5 into and OLED which will spell out what you are putting in in morse ...

When the first radios and telegraph lines were put into service, essentially the only way to communicate was to use Morse code. The first transmitters had extremely inefficient designs by today’s ...
