Delay whit cancel

Projects General Guidance

Hello

i need help whit conditional buttons

[code= "It Is"

Button 1 (UP) Out 1

Button 2 (DOWN) Out 2

Button 3 (RIGTH) Out 3

Button 4 (LEFT) Out 4

Button 5 (ON PWM OFF) Out 5

Button 6 (2 Automatic Movements 12 seg) Out 2 y Out 3

it is my code for the button 6, i need help beacause I need after pressing the
button to activate, can disable the command (cancel) with any of the 6 buttons

Thanks

const int buttonPin = 8; // número del pin para el botón
const int ledPin1= 4; // número del pin del LED
const int ledPin2 = 5; // número del pin del LED

int buttonState = 0; // estado del botón (0 ó LOW es apagado y 1 ó HIGH es encendido)

void setup() {

pinMode(ledPin1, OUTPUT); // Se identifica el pin 4 como salida
pinMode(ledPin2, OUTPUT); // Se identifica el pin 5 como salida
pinMode(buttonPin, INPUT); // Se identifica el pin 8 como entrada
}

void loop(){

buttonState = digitalRead(buttonPin); // Leemos si el botón en pin2 está abierto o cerrado

if (buttonState == HIGH) { // Si está siendo pulsado es HIGH

digitalWrite(ledPin1, HIGH); // Y el LED se enciende
digitalWrite(ledPin2, HIGH); // Y el LED se enciende
delay(12000); //Tiempo de espera 12000 milisegundos
}
else {

digitalWrite(ledPin1, LOW); // Si no es asi, se apaga
digitalWrite(ledPin2, LOW); // Si no es asi, se apaga
}
}
[/code]

Please post code in code tags </>.

Did you see the Spanish forum section (Español)?

delay(12000);

The delay() function prevents the Arduino from doing everything. It can't read other buttons or respond in any way until that delay has finished.

boolean delayWithCancel(unsigned long duration) {
  unsigned long start = millis();
  while(millis()-start < duration) {
    if(digitalRead(Button1)==LOW) return true;
    if(digitalRead(Button2)==LOW) return true;
    if(digitalRead(Button3)==LOW) return true;
    if(digitalRead(Button4)==LOW) return true;
  }
  return false; //action wasn't cancelled
}
void loop() {
  if(delayWithCancel(12000)) Serial.println("Cancel button pressed!");
}

Morgan, I am very new to arduino (Programming).
I understand half of what you have explained, thank you.

could you tell me how then modify my code.
