Menu on Nokia 5110 Lcd Display With Arduino

We have published quite a number of tutorials using different displays with the Arduino, with the most recent being the tutorial on displaying graphics on all kind of displays with Arduino. For today’s tutorial, we will look into achieving more with displays by implementing a menu based system with the Nokia 5110 LCD display and the Arduino. The menu is one of the easiest and most intuitive ways through which users interact with products that require navigation. From mobile phone to PCs, its applications are endless. Today we will explore how to add this cool feature to your Arduino project.

MENU ON NOKIA 5110 LCD DISPLAY WITH ARDUINO

At the heart of today’s project is the Nokia 5110 LCD Display. The Nokia 5110 LCD is one of the most popular LCD display among makers. It was originally developed for use as a screen for cell phones and was used in lots of mobile phones during the 90’s. The display uses a low power CMOS LCD controller/driver, the PCD8544, which drives the 84×48px graphics display. In a normal state, the display consumes about 6 to 7mA which makes it quite ideal for low power devices. We have published quite a number of tutorials on this display that might help you understand how to drive such a display.

To showcase how to create the menu on a display with the Arduino, we will build a simple demo menu with three pages.  To navigate through the menu, we will use 3x push buttons. The first to scroll up, the second to scroll down and the third one to select a highlighted option. The first screen/page of the menu will serve as the home page and will host the options that open the next two screens/pages. The second page will open after the first menu option on the homepage has been selected. Users will be able to change the contrast of the display using the up and down push buttons to increase or reduce it respectively. By pressing the select button, users will be able to go back to the home page. The second option on the homepage displays the third page, where users will be able to turn the backlight of the display on/off by pressing the select item button.

Selecting the last option on the homepage does what it is labeled for, it clears all the previous settings for the contrast and backlight. This is a fun and interesting project which I believe can be very useful to anyone irrespective of your technical know-how level.

That’s it for introduction, Let’s now see how to build this project.

Required Components

The following components are required to build this project;

  1. Arduino Uno
  2. Nokia 5110 LCD 
  3. Small Breadboard
  4. Buttons
  5. Jumper Wires
  6. Wires

As usual, the exact components used for this tutorial can be bought via the link attached to each of them.

Schematics

The schematics for this project is quite simple, connect the components as shown in the schematics below.

To make the schematics easy to follow, a pin map of the connection between the Arduino Uno and the Nokia 5110, which isthe major component, is shown below.

LCD - Arduino
RST - D12 
CE  - D11 
DC  - D10 
DIN - D9 
CLK - D8 
VCC - VCC
LIGHT - D7
GND - GND

Looking at the schematics, you will see that the push buttons are connected to the Arduino without the common pull-up or pull-down resistors. This is because we will use the Arduino’s internal pull-up resistor. You can read more about using pull-up/down resistors here. If you have any challenges understanding the concept, do reach out to me via the comment section.

With the connections all done, we can now proceed to the code for the project. It might be useful to go over the entire connection one more time to ensure everything is as it should be.
