Pin 20 on a 16 pin dip?

In the Fritzing I see no connection from pin 16 to the 5V logic supply. I would also suggest that you take out the serial part and try hard coding the steps variable. Get one thing working at a time.
pin 20, not pin 16, this has already been pointed out.
As groundfungus said . Also do not hook up the motor supply to pin 16.
