Hello Jack Christensen

[ludo5959]

Many thancks , for your work and of course your help for beginner. j m front of your job about your button programe

include //https://github.com/JChristensen/Button

define int BUTTON_PIN 2 //Connect a tactile button switch (or something similar)

                       //from Arduino pin 2 to ground.

define int PULLUP true //To keep things simple, we use the Arduino's internal pullup resistor.

define int INVERT true //Since the pullup resistor will keep the pin high unless the

                       //switch is closed, this is negative logic, i.e. a high state

                       //means the button is NOT pressed. (Assuming a normally open switch.)

define int DEBOUNCE_MS 20 //A debounce time of 20 milliseconds usually works well for tactile button switches.

define LED_PIN 13 //The standard Arduino "Pin 13" LED

Button myBtn(2,true, true, 20); //Declare the button

boolean ledState; //A variable that keeps the current LED status

void setup(void)

{

pinMode(LED_PIN, OUTPUT);    //Set the LED pin as an output

}

void loop(void)

{

myBtn.read();                    //Read the button

if (myBtn.wasReleased()) {       //If the button was released, change the LED state

    ledState = !ledState;

    digitalWrite(LED_PIN, ledState);

}

} it doesnt work , j get your button librairie in my blilio. please may you help me
