Codi per codificació en morse per Arduino

Canvis en el codi

El codi sense canvis l'he tret de la pagina https://create.arduino.cc/projecthub/electropeak/how-to-make-a-morse-code-translator-with-arduino-d6ecc8?ref=user&ref_id=573543&offset=1 on es explica pas a pas com fer-ho.


Els canvis que he fet per a que funciones correctament amb l'Arduino MKR1000 han sigut que he eliminat la funcio "const int buz = 8;" que hi ha al principi i cap al final del codi en "void setup()" he afegit la funcio "pinMode(8,OUTPUT)" per a que pases energia pel pin 8 i a continuacio en "void dot()" i "void dash()" he substituit tots els "digitalWrite(buz,HIGH)" i "digitalWrite(buz,LOW) per "tone(8,349,200)" ja que ens dona la posibilitat de posar una frequencia i un temps per tenir un millor control.


Hi ha moltes formes de fer aquest codi i la forma en que l'he fet jo es diu switch que en aquest cas consisteix a posar-li a cada lletra i numero els punts(dot) i guillons(dash) que equivalguin en el llenguatge morse.
