Tutorial Projek Elektronik Arduino: Tutorial 7:Cara menguji LCD dan Arduino

Untuk tutorial projek elektronik pada kali ini,saya akan menunjukkan untuk menguji LCD.Dengan cara ujian ini,anda dapat menentukan point dibawah ini.

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.

This example code is in the public domain.

http://www.arduino.cc/en/Tutorial/LiquidCrystal

// 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 .
