Hello Everyone
I wanna do a procedure but it should stop if I press a button, so I can't do it with delays and the Tutorial on Yt isn't really helping. Can someone give me an example? My other question is how can I make an integer just count 1 every time I press it and if I press a Stop button it should go back to 0. Thx
Which tutorial? What have you tried so far?
This is the "Blink without delay()" code from arduino website:
// constants won't change. Used here to set a pin number:
const int ledPin = LED_BUILTIN;// the number of the LED pin
// Variables will change:
int ledState = LOW; // ledState used to set the LED
// Generally, you should use "unsigned long" for variables that hold time
// The value will quickly become too large for an int to store
unsigned long previousMillis = 0; // will store last time LED was updated
// constants won't change:
const long interval = 1000; // interval at which to blink (milliseconds)
void setup() {
// set the digital pin as output:
pinMode(ledPin, OUTPUT);
}
void loop() {
// here is where you'd put code that needs to be running all the time.
// check to see if it's time to blink the LED; that is, if the difference
// between the current time and last time you blinked the LED is bigger than
// the interval at which you want to blink the LED.
unsigned long currentMillis = millis();
if (currentMillis - previousMillis >= interval) {
// save the last time you blinked the LED
previousMillis = currentMillis;
// if the LED is off turn it on and vice-versa:
if (ledState == LOW) {
ledState = HIGH;
} else {
ledState = LOW;
}
// set the LED with the ledState of the variable:
digitalWrite(ledPin, ledState);
}
}
It can be modified to do what you need.
Variable incrementation can be done using
variable++; //Use interrupt here to detect button press.
and reseting
if(buttonReset == HIGH){ //If reset button has been pressed set the variable to 0.
variable == 0;
}
