This is an easy assembly from a Arduino Uno kit, trying out the code just for fun and see how the system works. Mostly because I hadn't tried it before.
Basically connect like this:
/*
*

*/
#include <LiquidCrystal.h> // includes the LiquidCrystal Library
LiquidCrystal lcd(7, 8, 9, 10, 11, 12); // Creates an LC object. Parameters: (rs, enable, d4, d5, d6, d7)
int backLight = 13; // set pin 13 to control the backlight;
void setup() {
// put your setup code here, to run once:
lcd.begin(16,2); // Initializes the interface to the LCD screen, and specifies the dimensions (width and height) of the display }
lcd.print("hello, world!");
pinMode (backLight, OUTPUT);
digitalWrite(backLight,HIGH);
lcd.clear();
lcd.begin(16,2);
lcd.setCursor(0,0);
lcd.print("Hello, World"); // can change any words you want;
lcd.setCursor(0,1);
lcd.print("I feel good!"); // can change any words you want;
}
void loop() {
// put your main code here, to run repeatedly:
delay(3000);
lcd.clear(); // Clears the display
lcd.print("Arduino"); // Prints "Arduino" on the LCD
delay(3000); // 3 seconds delay
lcd.setCursor(2,1); // Sets the location at which subsequent text written to the LCD will be displayed
lcd.print("Makes magic");
delay(3000);
lcd.clear(); // Clears the display
lcd.blink(); //Displays the blinking LCD cursor
delay(4000);
lcd.setCursor(7,1);
delay(3000);
lcd.noBlink(); // Turns off the blinking LCD cursor
lcd.cursor(); // Displays an underscore (line) at the position to which the next character will be written
delay(4000);
lcd.noCursor(); // Hides the LCD cursor
lcd.clear(); // Clears the LCD screen
}
I did not clean up this code, so use it for what it is, just a test!
