INTRODUCTION
In one of our previous tutorials we did an introduction on how to use the Nokia 5110 LCD with the Arduino, the tutorial covered displaying texts with different fonts etc. For this tutorial, we are taking things a little bit further and will be working through the display of customized graphics on the Nokia 5110 LCD display. This tutorial will particularly be useful for those who want to display their brand logo or any other kind of image on the LCD asides ordinary texts.
The Nokia 5110 display is basically a graphic LCD display useful for a lot of applications. It was intended originally to be used as a screen for cell phones and was used in lots of mobile phones during the 90’s. This display uses a low powered CMOS LCD controller/driver PCD8544, which drives the graphic display of size 84×48. In a normal state, the display consumes about 6 to 7mA which makes it quite ideal for low power usage.
A detailed explanation on the operational principle of the display is found here.

SCHEMATICS
To interface with a micro controller and power itself, the display has two parallel 8-pin port to which headers pins can be connected. You can pick one of the sides and solder header pins to it for connection to the Arduino board.
There are two main power sources needed. The first one is the operational power supply which according to the data sheet should be between the range of 2.7V to 3.3V. The second power supply is required for the LCD back-light. The LCD circuit has no current limiting resistor inbuilt so its better to play safe and only power with 3.3V max.
The LCD is connected to the Arduino as shown in the Schematics below.
