// In this example we'll setup a callback for a mechButton.

#include <mechButton.h>

#define BTN_PIN	2     // Pin we'll hook the button to. The other side hooks to ground.
#define RED_PIN	13    // Usual pin number for built in LED.

mechButton  aButton(BTN_PIN);  // Set button one to pin BTN_PIN.
bool        state;

// Your standard sketch setup()
void setup() {
   
  Serial.begin(115200);              // Fire up our serial monitor thing.
  state = false;
  pinMode(RED_PIN,OUTPUT);           // Set up the LED pin for output.
  digitalWrite(RED_PIN,state);        // Set true because it ain't pushed yet.
  aButton.setCallback(myCallback);   // Set up our callback. (Also calls hookup() for idling.)
}


// This is the guy that's called when the button changes state.
void myCallback(void) {

  if (!aButton.getState()) {            // If the button has been pressed..
    if (state) {                        // If state..
      Serial.println("Do thing 2");     // We'll do 2.
    } else {                            // Else..
      Serial.println("Do thing 1");     //  we'll do 1.
    }                                   //
    state = !state;                     // Swap state.
    digitalWrite(RED_PIN,state);        // Show state.                   
  }                                   
}


// Your standard sketch loop()
void loop() { idle();	 }                // Let all the idlers have time to do their thing.
