    Please include the entire setup() function. – Craig Apr 13 '18 at 16:58
  • Serial.begin(9600); is missing – PhillyNJ Apr 14 '18 at 0:02

There can be different reasons, among:

  • The speed of the serial port does not match with the serial 'monitor'
  • The speed of the serial port is not set at all (can cause first problem)

I don't see this before the print statements: Serial.begin(9600); // or some other speed

That will prevent anything from printing.
