Finally, connect the pins to your Arduino 

GND goes to ground
Vin goes to 5V
SDA to I2C Data (on the Uno, this is A4 on the Mega it is 20 and on the Leonardo digital 2)
SCL  to I2C Clock(on the Uno, this is A5 on the Mega it is 21 and on the Leonardo digital 3)
RST to digital 4  (you can change this pin in the code, later)

This matches the example code we have written. Once you get this working, you can change

the RST pin. You cannot change the I2C pins, those are 'fixed' in hardware

Finally you can run
