Raspberry Pi Pico Morse Code Translator (Button + OLED Display + Buzzer)

Tap the button and the Pico decodes your Morse! We are building a Morse code translator with a Raspberry Pi Pico that works like a telegraph key. A short press is a dot, a long press a dash; the buzzer beeps along and the OLED display shows each decoded letter in large type. A second button plays your text back in Morse, so you see both directions.
