  state machine, yes, but maybe "detect tap" and "detect long-press"
  would yield better google results

  basic premise:
*/

const int myButton = 12;
const int PRESSED = LOW;

int lastState = HIGH;
unsigned long pressedMillis = 0;

void setup() {
  Serial.begin(115200);
  pinMode(myButton, INPUT_PULLUP);

}

void loop() {
  if (digitalRead(myButton) == PRESSED) {
    if (lastState != PRESSED) {
      lastState = PRESSED;
      pressedMillis = millis();
    }
  } //else {
    if (lastState == PRESSED) {
      if ((millis() - pressedMillis) > 350) {
        Serial.println("You long-pressed!\n");
      } else {
        Serial.println("You tapped!\n\n");
      }
      lastState = !PRESSED;
    }
  //}
