Learn and Understanding of LCD 16x2 with Arduino Uno

Let's play and learn with LCD 16x2 and arduino Uno.

Material needs:
- Arduin Uno
- LCD 16x2 Module

Arduino Uno

LCD 16x2 Module

Write down this sketch:

//Sample using LiquidCrystal library
#include <LiquidCrystal.h>                             // LCD library. downloaded here.
#include <delay.h>                                         // Library include in IDE.

// select the pins used on the LCD panel
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);                   // Define pin LCD module

void setup()
{
  lcd.begin(16,2);                                            // Initialization LCD 16x2
  lcd.setCursor(4,0);                                       // position cursor on 5th character on first column
  lcd.print("HOHOHO");                                // Type as HOHOHO
  lcd.setCursor(2,1);                                       // position cursor on 3nd character on second column
  lcd.print("Arduino World");                           // type as Arduino World
}
void loop(){}

Here is the pinout of the shield

Pin out LCD module

Starting character is from 0 to 15. so totally character is 16 character.
if you type lcd.setCursor(4,0); it means starting on 5th and first column.
4 --> 0 to 4 = 5 character
0 --> column used

I hope you understand with my explanation.
If you would to ask me, feel free to contact in comment.

Thanks
