LCD display

Here is the hardware list: Arduino BoardLCD Screen (compatible with Hitachi HD44780 driver), pin headers to solder to the LCD display pins, 10k Potentiometer, breadboard, hook-up wire
We need to hookup our LCD display to our Arduino. The display can use any of the Arduino digital I/O pins as it has no special requirements, but if you hook it up as I’ve illustrated here you can run the example sketches without needing to make any modifications.
Liquid Crystal displays or LCDs have been used in electronics equipment since the late 1970s.   LCD displays have the advantage of consuming very little current and they are ideal for your Arduino projects.  A number of LCD displays are available for experimenters. These low-cost monochrome displays are ideal for use with microcontrollers like the Arduino and micro computers like the Raspberry Pi. These displays are available in a number of different configurations. The part number for the display generally relates to the number of rows and columns in the display. Common display configurations include 16 x 2, 16 x 4 and 20 x 4.  All of these displays are used in a virtually identical fashion the only difference being the number of columns and rows they have.
