Morse Converter Shield Arduino UNO understands dah-dit-dah

摘要

Back in 1836 with no IoT or Wi-Fi around one Samuel Morse demonstrated the ability of a telegraph system to transmit information over wires. The information was sent as a series of electrical signals to an agreed protocol. 150+ years on, Morse is still alive and has its staunch supporters. Let's see if Arduino can help us decode these mysterious beeper-di-beep signals.
