Adding action buttons

I also added two action buttons to my Miata's dash so that I can wink the popups with just a button press.

Button case​

If you don't want to model anything by yourself you can just use my model. It is designed to work with two of these buttons.

Button wiring​

If you also have two buttons like I do, you need 3 wires to the button one to GND and the other two to the pins defined in the script below. To trigger a button it just needs to be shorted to GND.

Arduino code​

Now we have to add the code for these action buttons to the same script.
So add these definitions and pin modes:

const int aButton1Pin = 6;
const int aButton2Pin = 7;

bool lastAButton1Val;
bool lastAButton2Val;

void setup() {
  pinMode(aButton1Pin, INPUT);
  pinMode(aButton2Pin, INPUT);

  digitalWrite(aButton1Pin, HIGH);
  digitalWrite(aButton2Pin, HIGH);
}

And to read the button and send all changes to the unity application we need to add this to the code:

void loop() {
  checkActionButton1();
  checkActionButton2();
}

void checkActionButton1() {
  bool aButton1Val = digitalRead(aButton1Pin);

  if (lastAButton1Val != aButton1Val) {
    lastAButton1Val = aButton1Val;
    onActionButton1Changed(aButton1Val);
  }
}

void checkActionButton2() {
  bool aButton2Val = digitalRead(aButton2Pin);

  if (lastAButton2Val != aButton2Val) {
    lastAButton2Val = aButton2Val;
    onActionButton2Changed(aButton2Val);
  }
}

void onActionButton1Changed(bool val) {
  if (val) {
    Serial.println("a1u");
  } else {
    Serial.println("a1d");
  }
}

void onActionButton2Changed(bool val) {
  if (val) {
    Serial.println("a2u");
  } else {
    Serial.println("a2d");
  }
}
