Features

  • Dimensions: 3.15" x 1.425"

Usage

Works on either 4 bit or 8 bit mode. For Arduino LCD library, Please refer to http://arduino.cc/en/Reference/LiquidCrystal?from=Tutorial.LCDLibrary.

Connections to Arduino

The circuit:

  • LCD RS pin to digital pin 12


  • LCD Enable pin to digital pin 11


  • LCD D4 pin to digital pin 5


  • LCD D5 pin to digital pin 4


  • LCD D6 pin to digital pin 3


  • LCD D7 pin to digital pin 2


Parallel LCDs run off of +5V so you can just solder the Vcc (pin 2 in LCD)wire to 5V and the ground (pin 1 in LCD) wire to GND.


  • 10K resistor:
  • ends to +5V and ground
  • wiper to LCD VO pin (pin 3)
