Push Button State Change (Multiple Conditions)

Projects Programming

@blh64 I appreciate the sincere response. Here's the updated code aka my attempt (it won't even compile)-


const int buttonPin = 3;    // the number of the pushbutton pin
const int ledPin = 13;      // the number of the LED pin

const int powerPin = 4;    // the number of the input power pin

// Variables will change:
int ledState = HIGH;        // the current state of the output pin
int buttonState;            // the current reading from the input pin
int lastButtonState = LOW;  // the previous reading from the input pin

int machineState;           // current reading from the power pin
int lastmachineState;       // previous readin from the power pin


// the following variables are long's because the time, measured in miliseconds,
// will quickly become a bigger number than can be stored in an int.
unsigned long lastDebounceTime = 0;  // the last time the output pin was toggled
unsigned long debounceDelay = 50;    // the debounce time; increase if the output flickers

unsigned long lastDebounceTime1 = 0;  // the last time the output pin was toggled
unsigned long debounceDelay1 = 50;    // the debounce time; increase if the output flickers


void setup() 
{
  Serial.begin(9600);
  pinMode(buttonPin, INPUT_PULLUP);
  pinMode(ledPin, OUTPUT);

  // set initial LED state
  digitalWrite(ledPin, ledState);
}

void loop() 
{
  // read the state of the switch into a local variable:
  int reading = digitalRead(buttonPin);
  int mreading = digitalRead(powerPin);
  // check to see if you just pressed the button 
  // (i.e. the input went from LOW to HIGH),  and you've waited 
  // long enough since the last press to ignore any noise:  
  // If the switch changed, due to noise or pressing:
  
  
  if (mreading != lastmachineState)
  {
      lastDebounceTime1 = millis();
  }


  if ((millis() - lastDebounceTime1) > debounceDelay1) 
  {
    // whatever the reading is at, it's been there for longer
    // than the debounce delay, so take it as the actual current state:
    // if the button state has changed:

    if (mreading != machineState)
   {
    machineState = reading;
    if (machineState == HIGH)
    {
      Serial.println("MACHINE ON")
   
    if (reading != lastButtonState) 
  {
    // reset the debouncing timer
    lastDebounceTime = millis();
  } 

 

  if ((millis() - lastDebounceTime) > debounceDelay) 
  {
    // whatever the reading is at, it's been there for longer
    // than the debounce delay, so take it as the actual current state:
    
    
    if (reading != buttonState) 
    {
      buttonState = reading;
      ledState = !ledState;
      digitalWrite(ledPin, ledState);
     
      if (buttonState == HIGH) 
      {
        Serial.println("LED ON");
      }
      else
      {
        Serial.println("LED OFF");
      }
    }
    else
    Serial.println("MACHINE OFF")
}
}
}
}
}
  // save the reading.  Next time through the loop,
  // it'll be the lastButtonState:
  lastButtonState = reading;
}

Here's what I thought would work, but I can imagine it serial printing this-

MACHINE ON
LED ON
MACHINE ON
LED OFF
MACHINE ON
LED ON...

and I don't want that.
