Using Arduino Analog Pins to Interact with LCD

Following the arduino tutorial, http://arduino.cc/en/Tutorial/AnalogInputPins it was quite clear that the Analog Pins can be used as its Digital counterpart. Except with a little different way of identification, i.e. prefixing the respective Analog pin with the character 'A' (A for Analog). 

The significance of this feature was overlooked until recently I desperately needed numerous digital pins, and I ran out of them on my Arduino (Atmega328) clone to drive Hitachi HD44780 compatible LCD. 

People suggested to use shift registers or I2C backpack etc., though, I wanted something more simpler and ultimately following the below mentioned tweaking, I got the LCD up and running using Analog pins. No rocket science, but felt happy, as I had saved my pocket from the extra expenses!!!

Display	Original	Our Experiment
RS	12	A0
RW	GND	GND
EN	11	A1
D4	5	A2
D5	4	A3
D6	3	A4
D7	2	A5

At the same time the code needs to be slightly changed, shown as below.

// Replace LiquidCrystal lcd(12, 11, 5, 4, 3, 2); with

LiquidCrystal lcd(A0, A1, A2, A3, A4, A5);

This shall use all Analog pins, though, the user is spared with all digital pins free, if the it is the sketch's demand .
