These displays use SPI to communicate, 4 or 5 pins are required to
interface

// Date and time functions using a DS1307 RTC connected via I2C and Wire lib
/* niq_ro ( http://nicuflorica.blogspot.ro ) case for Nokia 5110 LCD (PCD8544) - LPH 7366:
For module from China, you must connect like this:
* Pin 1 (RST) -> Arduino digital 6 (D6)
* Pin 2 (CE) -> Arduino digital 7 (D7)
* Pin 3 (DC) -> Arduino digital 5 (D5)
* Pin 4 (DIN) -> Arduino digital 4 (D4)
* Pin 5 (CLK) - Arduino digital 3 (D3)
* Pin 7 (LIGHT) -> +5V thru 56-100 ohms resistor (for permanent lights) or... other pin control
* Pin 8 (GND) -> GND1 or GND2
