Amazing, but please tell me if there is any easier way to check if button is pressed?

To check if a button is currently pressed:

  if (digitalRead(buttonPin))
    Serial.println("Button is currently pressed");

To check if a button has just gone from unpressed to pressed:

  static boolean lastButtonState = false;
  boolean curentButtonState = digitalRead(buttonPin);
  if (currentButtonState != lastButtonState) { // State has changes
    lastButtonState = currentButtonState;
    if (currentButtonState)
      Serial.println("Button was just pressed");
    else 
      Serial.println("Button was just released/");
