This post shows how interface Arduino UNO board with Nokia 5110 (3310) graphical LCD screen.
The name Nokia 5110 (3310) comes from Nokia 5110 (or Nokia 3310) mobile phone. The Nokia 5110 LCD has a controller named PCD8544, it is similar to the Nokia 5110 mobile phone LCD, it uses SPI interface protocol and requires 5 control pins (or 4 pins), it’s low cost and easy to use. The resolution of this LCD is 84 x 48 which means it has 4032 pixels. This module works with 3.3V only and it doesn’t support 5V (it’s not 5V tolerant).

Hardware Required:

Arduino board
Nokia 5110 (3310) LCD module
5 x 3.3k ohm resistor
5 x 2.2k ohm resistor
Breadboard
Jumper wires

Interfacing Arduino with Nokia 5110 LCD circuit:
Example circuit diagram is shown below.

The Nokia 5110 which is shown in the circuit diagram has 8 pins (from left to right): RST (reset), CE (chip enable), DC (or D/C: data/command), Din (data in), Clk (clock), VCC (3.3V), BL (back light) and Gnd (ground).

As mentioned above, the Nokia 5110 LCD works with 3.3V only (power supply and control lines). The LCD module is supplied with 3.3V which comes from the Arduino board (VCC pin of the LCD is connected to Arduino 3.3V pin), BL pin is also connected to 3.3V.

All Arduino UNO board output pins are 5V, connecting a 5V pin to the Nokia 5110 LCD may damage its controller circuit.
To connect the Arduino to the LCD module, I used voltage divider for each line which means there are 5 voltage dividers. Each voltage divider consists of 2.2k and 3.3k resistors, this drops the 5V into 3V which is sufficient.

Interfacing Arduino with Nokia 5110 LCD code:
The following Arduino code requires two libraries from Adafruit Industries:
The first library is a driver for the Nokia 5110 LCD (PCD8544 controller) which can be installed from Arduino IDE library manager (Sketch —> Include Library —> Manage Libraries …, in the search box write “nokia” and install the one from Adafruit).

The second library is Adafruit graphics library which can be installed also from Arduino IDE library manager.

The previous two libraries can also be installed manually:
Download both libraries from the following two links:
Adafruit Nokia 5110 LCD library —-> direct link
Adafruit graphics library —-> direct link

Go to Arduino IDE —> Sketch —> Include Library —> Add .ZIP Library … and browse for the .zip file (previously downloaded).
The same thing for the second file.

After installing the two libraries, go to Arduino IDE —> File —> Examples —> Adafruit PCD8544 Nokia 5110 LCD library —> pcdtest, as shown in the following image:
