Time

I just found out about the Button State arduino example. To sum up the code, each time i press a button, then a value is added to a button counter. Then the number value is printed in to serial terminal.

When i hold the button the value adds up and does not stop.

My question is if there is a why i can add code that states, if the button is pressed for 1000 millisecounds then buttonstate = LOW.

the main part of my question "is if pressed for 1000 milliseconds"

here is the code for those of you who need it

!!AND THANKS IN ADVANCE!!

const int  buttonPin = 2;    // the pin that the pushbutton is attached to
const int ledPin = 13;       // the pin that the LED is attached to

// Variables will change:
int buttonPushCounter = 0;   // counter for the number of button presses
int buttonState = 0;         // current state of the button
int lastButtonState = 0;     // previous state of the button

void setup() {
  // initialize the button pin as a input:
  pinMode(buttonPin, INPUT);
  // initialize the LED as an output:
  pinMode(ledPin, OUTPUT);
  // initialize serial communication:
  Serial.begin(9600);
}


void loop() {
  // read the pushbutton input pin:
  buttonState = digitalRead(buttonPin);

  // compare the buttonState to its previous state
  if (buttonState != lastButtonState) {
    // if the state has changed, increment the counter
    if (buttonState == HIGH) {
      // if the current state is HIGH then the button
      // wend from off to on:
      buttonPushCounter++;
      Serial.println("on");
      Serial.print("number of button pushes:  ");
      Serial.println(buttonPushCounter);
    } 
    else {
      // if the current state is LOW then the button
      // wend from on to off:
      Serial.println("off"); 
    }
  }
  // save the current state as the last state, 
  //for next time through the loop
  lastButtonState = buttonState;

  
  // turns on the LED every four button pushes by 
  // checking the modulo of the button push counter.
  // the modulo function gives you the remainder of 
  // the division of two numbers:
  if (buttonPushCounter % 4 == 0) {
    digitalWrite(ledPin, HIGH);
  } else {
   digitalWrite(ledPin, LOW);
  }
  
}

Looks like you could use this library from Nick Gammon:
http://gammon.com.au/Arduino/SwitchManager.zip

//http://gammon.com.au/Arduino/SwitchManager.zip
#include <SwitchManager.h>
SwitchManager modeSW;  // create the object

const byte ModeSW = 2;              //input from the Mode push button switch     

void setup ()
{
  Serial.begin(9600);  
  modeSW.begin (ModeSW, modeSwitchManager);
}
//======================== END OF setup ==========================

void loop (){
  //check to see what's happening with the Mode switch
  modeSW.check();

  // put other loop() code here



}
//======================== END OF loop ===========================

void modeSwitchManager (const byte newState, const unsigned long interval)
{
  if (newState == HIGH )
  {
    // N E W S A T E   I S   H I G H
    Serial.print ( "The switch was LOW for: ");
    Serial.print (interval);
    Serial.println( " milli seconds");

    return;

  }

  // N E W S A T E   I S   L O W
  Serial.print ( "The switch was HIGH for:");
  Serial.print (interval);
  Serial.println( " milli seconds");

  return;



}  //                  END of modeSwitchManager()

You may also get some benifit from his thread:

When i hold the button the value adds up and does not stop.

Something is wrong here. If you press and hold the button it should register only once. It counts transitions not levels. How is your button wired?

The answer is yes, of course.

When you spot that the button has become pressed save the start time from millis(). While it remains pressed check each time through loop() to see if 1000mS has elapsed by subtracting the start time from the current millis(). If it is greater than 1000 then time is up so do what you want. If not then keep going round loop().
