    Standard HD44780 LCDs are useful for creating standalone projects.

    20 characters wide, 4 rows

    black text on Yellow background

    Connection port is 0.1" pitch, single row for easy Breadboarding and wiring

    Single LED backlight with a resistor included, you can power it directly from 5V. If it's too bright for you, it can be dimmed easily with a resistor or PWM and uses much less power than LCD with EL (electroluminescent) backlights

    Can be fully controlled with only 6 digital lines!

    The built-in character set supports English/Japanese text, see the HD44780 datasheet for the full character set

    Up to 8 extra characters can be created for custom glyphs or 'foreign' language support (like special accents)

    Picture of Schematic


    The LCD we are using has 16 pins. Description of each pin is as follows:

    Pin No Symbol Level Description

    1 VSS 0V Ground

    2 VDD 5V Supply Voltage for logic

    3 VO (Variable) Operating voltage for LCD

    4 RS H/L H: DATA, L: Instruction code

    5 R/W H/L H: Read(MPU?Module) L: Write(MPU?Module)

    6 EH H->L chip enable signal

    7 DB0 H/L Data bus line

    8 DB1 H/L Data bus line

    9 DB2 H/L Data bus line

    10 DB3 H/L Data bus line

    11 DB4 H/L Data bus line

    12 DB5 H/L Data bus line

    13 DB6 H/L Data bus line

    14 DB7 H/L Data bus line

    Picture of Code

    There are two options that you can follow, either you can build up your own code, if you know how to or you can use the example code from the built-in Arduino library "LiquidCrystal.h".

    we have used the HelloWorld example from the library. You can find this example in Arduino IDE following the path: File->Examples->LiquidCrystal->HelloWorld.

    don't forget to change the 16,2 in the lcd.begin to 20,4.

    Now connect the Arduino to any of the USB ports and upload the code.
    Once the code is uploaded, you must be able to see "hello, world" printed on the LCD.
