UE4 Arduino Color Mixer 2

/*
  DigitalReadSerial

  Reads a digital input on pin 2, prints the result to the Serial Monitor

const int potPin01 = A0;
const int potPin02 = A1;
const int potPin03 = A2;

// digital pin 2 has a pushbutton attached to it. Give it a name:
int pushButton = 2;

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
  // make the pushbutton's pin an input:
  pinMode(pushButton, INPUT);
}

// the loop routine runs over and over again forever:
void loop() {
    // print out the state of the potentiometers
  Serial.print(analogRead(potPin01));
  Serial.print(",");
  Serial.print(analogRead(potPin02));
  Serial.print(",");
  Serial.print(analogRead(potPin03));
  Serial.print(",");

  // read the input pin:
  int buttonState = digitalRead(pushButton);

  // print out the state of the button:
  Serial.println(buttonState);

  delay(1);        // delay in between reads for stability
