Lcd Librairy problem

I have the same LCD as you and hooked this up just last week. I followed the example sketch called LCD_Example (under the File, Examples, Display).

Here's the sketch:

// character LCD example code
// www.hacktronics.com

#include <LiquidCrystal.h>

// Connections:
// rs (LCD pin 4) to Arduino pin 12
// rw (LCD pin 5) to Arduino pin 11
// enable (LCD pin 6) to Arduino pin 10
// LCD pin 15 to Arduino pin 13
// LCD pins d4, d5, d6, d7 to Arduino pins 5, 4, 3, 2
LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);

int backLight = 13; // pin 13 will control the backlight

void setup()
{
pinMode(backLight, OUTPUT);
digitalWrite(backLight, HIGH); // turn backlight on. Replace 'HIGH' with 'LOW' to turn it off.
lcd.begin(16,2); // columns, rows. use 16,2 for a 16x2 LCD, etc.
lcd.clear(); // start with a blank screen
lcd.setCursor(0,0); // set cursor to column 0, row 0 (the first row)
lcd.print("Hello, World"); // change this text to whatever you like. keep it clean.
lcd.setCursor(0,1); // set cursor to column 0, row 1
lcd.print("hacktronics.com");

// if you have a 4 row LCD, uncomment these lines to write to the bottom rows
// and change the lcd.begin() statement above.
//lcd.setCursor(0,2); // set cursor to column 0, row 2
//lcd.print("Row 3");
//lcd.setCursor(0,3); // set cursor to column 0, row 3
//lcd.print("Row 4");
}

void loop()
{
}

I think I blow up the LCD, I'll try to buy a new one and start again.

I have verify all pin with Arduino and a LED to check if the Arduino was sending to the pin something and I can light up LED so I guess the Arduino do its job.

I'll try once again to connect everything. ::slight_smile:

I made it works!

And I have followed : Arduino Tutorial - connecting a parallel LCD
like I was doing before.

I guess one of my wire must have been placed in the wrong place or have been not fully inserted in the breadboard... don't know!

Thanks everybody!
