|---|---|
| 1 | This pin used for grounding the display |
| 2 | This is used for giving voltage supply to the display |
| 3 | This pin will give the clock signal for both types of communication either SPI or I2C |
| 4 | The fourth pin is the data pin through which it will receive data from Arduino |
128×64 Graphical LCD display for Arduino
This display comes with different models of LCD drivers and its pin configuration depends on the model of LCD driver. This display is much bigger in size as compared to other displays as it has 128 columns and 64 rows for displaying the data. Similarly, this module can be used to display the characters of different sizes by using different pixel combinations and also it supports the feature of displaying the animations and images. The operating voltage for this display is 5 volts and the interfacing of this module is similar to the 16×2 liquid crystal display.
Here we have used the display having the graphic display having a driver model of KS0108 which has 20 pins in total.

Nokia 5110 Liquid crystal display for Arduino
This display has 84×48 pixels having total 8 pins and operates only on 3.3 volts. This type of display is used where a basic level of graphical user interface is required as from the name it is clear that this display was used for Nokia 5110 cell phone. Similarly, this display is a better option as compared to the 16×2 liquid display as it has better graphics and can display a large number of custom characters.

| 8(GND) | For Grounding the display |
Conclusion
For displaying the inputs and outputs of the Arduino program different types of displays can be interfaced with Arduino boards. The type of display depends on its compatibility with Arduino board and type of the data that is to be displayed on the module. In this write-up five best compatible display modules are given with their pin configuration and technical specifications.
