Untuk tutorial projek elektronik pada kali ini,saya akan menunjukkan untuk menguji LCD.Dengan cara ujian ini,anda dapat menentukan point dibawah ini.
- Wiring Arduino ke LCD adalah betul
- Cable Arduino ke LCD dalam keadaan Baik
- Arduino anda dalam keadaan baik
- LCD anda dalam keadaan baik
Langkah 1 :
Sambung LCD dan Arduino seperti gambarajah dibawah :
Setelah selesai wiring,copy dan paste program di bawah:

LiquidCrystal Library - Hello World
Demonstrates the use a 16x2 LCD display. The LiquidCrystal
library works with all LCD displays that are compatible with the
Hitachi HD44780 driver. There are many of them out there, and you
can usually tell them by the 16-pin interface.
This sketch prints "Hello World!" to the LCD
and shows the time.

*/
// include the library code:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(8, 9, 10, 11, 12, 13);
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print("hello, world!");
}
void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
lcd.print(millis() / 1000);
}

Anda sepatutnya melihat tulisan hello world pada LCD anda. Jika tiada tulisan,Mesti buat bagi ada.Tukarlah apa yang patut .
