Why is my pushbutton always reading LOW? I know this is ridiculously simple task but I spent the last two hours trying to get this to work and it is not working.  I don't have an Arduino but I have an ESP8266 Huzzah Feather which is programmable via the Arduino IDE.  So, I don't think I can provide a Fritz diagram but in any case, I'm just trying to hook up a pushbutton and be able to read a HIGH or LOW (via my Serial monitor).  Currently, everything is 0.

As best I can describe it is:

5V from Feather into resistor into one terminal of the pushbutton.  Out the other terminal of the pushbutton is a wire connecting to pin 12 of the Feather, and also a wire leading to ground.  Feather is also grounded.  

My code is:

void setup()
{
  Serial.begin(9600);
  pinMode(12, INPUT);
}

void loop()
{
  int button_val = digitalRead(12);
  Serial.println(button_val);
}


It shouldn't be this hard for me.  Whenever I open and run the serial monitor, it reads 0s.  What am I missing?  

Oh, an issue that I faced is determining which 2 out of the 4 terminals of the pushbutton to use.  Some resources I find say that it is the same side as the terminal the voltage is flowing into; other resources say it is the terminal opposite to the side the voltage is flowing into.  I currently have it opposite.
The pins on each side of the button are shorted, the "button" is between the sides of the button. Else your code looks alright.

Edit: Here's an image which shows how a push button is connected internally, make sure you're using the correct pins.
