LCD4884 shield

by shedboy71

This was another shield that grabbed my attention, this LCD was used on older nokia phones. You can find it on the internet  at very reasonable rates.

LCD Features

resolution of 84 by 48 pixels
blue back light

Below the LCD is a four-way joystick with a built in button. This is connected to analog pin 0 via a resistor network. Here you can see a photograph of the shield and its running the example you will create later

Reading the joystick position is accomplished via analogRead(0);. Setup some Serial debugging, open the Serial monitor and move the joystick around and take note of the values. In your sketch you can use an if conditional statement to perform an action based on the value returned

The shield requires an Arduino library which is in the link at the bottom of the page.


The example below initiliases the display, clears the screen and the displays some text. Method 1 uses constants for the x and y positions, method 2 hard codes these values. As you can see there is a function called lcd.LCD_write_string that displays text on the screen

OK, download the library from the link at the bottom, copy it into the Libraries folder and lets get started


#include “LCD4884.h”

#define MENU_X 1
#define MENU_Y 1

void setup()
lcd.LCD_write_string(MENU_X, MENU_Y, “test screen 1”, MENU_HIGHLIGHT );
lcd.LCD_write_string(1, 3, “test screen 2”, MENU_HIGHLIGHT );

void loop()
