Arduino button and led program

Question

«Я пытаюсь создать программу, в которой у меня есть 6 режимов, управляемых с помощью одной кнопки, проблема в том, что после процедуры SOS процедура продолжается вечно и не соответствует кнопке нажмите до тех пор, пока я не вернусь к последнему S SOS. Ниже приведена программа, любезно объясняющая, как я могу выйти из подпрограммы нажатием кнопки.

Во-вторых, эта программа может быть преобразована в .hexfile ? для PIC12 микроконтроллеров? С уважением, Фавад»

// Uses button presses to switch an LED between off, dim, medium, high brightness & SOS. 


// constants for this sketch 
const int buttonPin = 2;  // pushbutton pin 
const int led = 9;   // LED pin 
int dit = 500;     //MORSE CODE dit 
int dah = dit*3;    //MORSE CODE dah 
int blankTime = 100;   // GAP IN BETWEEN DIT AND DAH 

// variables for this sketch 
int ledMode = 1; // variable for recording button presses 
int ledState = 6;

{ 
    // initialize the output pins: 
    pinMode(led, OUTPUT); 

    // initialize the pushbutton pin as an input: 
    pinMode(buttonPin, INPUT);

{ 
    // check if the pushbutton is pressed. 
    if (digitalRead(buttonPin) == HIGH)

Answer 1

Используйте digitalRead чаще.

Добавить кнопку, подтверждающую подпрограмму к середине и концу каждой буквы «SOS», чтобы очистить ledMode.

Как:

digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) 
    delay(dit);    // wait 
    digitalWrite(led, LOW); // turn the LED off by making the voltage LOW 
    delay(blankTime);   // wait 
    if (digitalRead(buttonPin) == HIGH) //READ 
    {  delay(100);     //DELAY 
    ledMode = ledMode + 0;    //CLEAR 
    digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) 
    delay(dit);    // wait 
    digitalWrite(led, LOW); // turn the LED off by making the voltage LOW 
    delay(blankTime);   // wait 
    if (digitalRead(buttonPin) == HIGH) //READ 
    {  delay(100);     //DELAY 
    ledMode = ledMode + 0;    //CLEAR  
    digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) 
    delay(dit);    // wait 
    digitalWrite(led, LOW); // turn the LED off by making the voltage LOW 
    delay(blankTime);   // wait 
    if (digitalRead(buttonPin) == HIGH) //READ 
    {  delay(100);     //DELAY 
    ledMode = ledMode + 0;    //CLEAR
