ARDUINO Library

The document discusses creating custom Arduino libraries. It explains that a library is written in C++ and includes header and source code files. The header file contains function declarations while the source file contains definitions. It also provides an example library structure and shows how to include a library and call its functions from a sketch.

Contoh library Morse

Morse.h

Morse.cpp
Morse.h Morse.cpp
#include “Arduino.h"
#ifndef Morse_h #include "Morse.h"
#define Morse_h
Morse::Morse(int pin)
#include “Arduino.h“ {
pinMode(pin, OUTPUT);
_pin = pin;
class Morse }
{
void Morse::dot()
public: {
Morse(int pin); digitalWrite(_pin, HIGH);
delay(250);
void dot(); digitalWrite(_pin, LOW);
void dash(); delay(250);
}

private: void Morse::dash()


{
int _pin; digitalWrite(_pin, HIGH);
}; delay(1000);
digitalWrite(_pin, LOW);
delay(250);
#endif }
Menggunakan Library
#include <headerfilelibarary.h> #include <Morse.h>

Morse morse(13);
// buat object class library void setup()
namaClass namaobjek {
}

void loop()
//Gunakan fungsi objeck yg sdh dibuat {
namaObject.fungsi morse.dot();
morse.dash();
delay(3000);
}
#ifndef Morse_h
#define Morse_h

// #include statment and code go here.

#endif

Kode tsb diatas untuk mencegah eror krn


penambahan file header lebih dari satu (doble).
#ifndef Morse_h
#define Morse_h
#include "Arduino.h"

public: untuk mencegah eror krn


void dot(); penambahan file header
void dash();
private:
Int _pin;

#endif
#include "Arduino.h"
Header file Arduino.h yg berisi fungsi2 dasar arduino antara lain :
pinMode();
digitalWrite();
digitalRead();
analogRead();
analogReference();
analogWrite();
millis();
micros(;
delay();
delayMicroseconds();

Header file Arduino.h Harus ditambahkan sendiri ke library


yg kita buat .
Contoh1 - Menggunakan Library LiquidCrystal.h

#include<LiquidCrystal.h> #include<LiquidCrystal.h>

// buat object class library LiquidCrystal lcd( 3,4,5,6,7,8)


namaClass namaobjek
void setup()
{
}
void loop()
{
//Gunakan fungsi objeck yg sdh
dibuat lcd.setCursor(0, 0);
namaObject.fungsi lcd.print("test");
}
