== 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)
