Tutorial Membuat Penerjemah Kode Morse (Morse Code Converter) Menggunakan Arduino via Serial Monitor di WOKWI

Panduan praktis pembuatan sistem penerjemah Kode Morse ke teks secara real-time atau text ke kode morse menggunakan mikrokontroler Arduino. Tutorial ini membahas pemrograman logika konversi sinyal Morse serta simulasi rangkaian secara interaktif menggunakan WOKWI Serial Monitor. Skematik rangkaian ditunjukkan pada Gambar 1, program Arduino pada Kode 1, dan video pembuatan pada tautan Video 1

Pemetaan PIN:
* BUZZER
GND – GND
OUT – 8
* LED
GND – GND
VCC – 7
