Modifikasi Door Lock Mobil dengan Arduino

Modifikasi Door Lock Mobil dengan Arduino

      Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuat simulasi dengan tujuan untuk modifikasi pintu mobil atau door lock mobil dengan ketentuan yaitu seperti berikut. Door switch = Trigger (-12V) lampu nyala, timer 5 menit mati Apabila trigger (-12V) hilang, tetap hidup selama 10 detik, Unlock = Trigger pulse (+12V), lampu nyala selama 10 detik, Lock = Trigger pulse (+12V), diatas tidak berfungsi, Kontak ON = Trigger (+12V), timer batal semua.

1. Program Arduino

#include <DS3231.h>

DS3231  rtc(SDA, SCL);

Time  t;

int doorswitch = 2;

int unlock = 3;

int lock = 4;

int kontakon = 5;

int relaylampu = 6;

int doorswitchx;

int unlockx;

int lockx;

int kontakonx;

int tanda = 0;

int kunci;

void setup() {

 Serial.begin(9600); 

 rtc.begin();  

 rtc.setDOW(WEDNESDAY);     // Set Day-of-Week to SUNDAY

 rtc.setTime(0, 0, 0);     // Set the time to 12:00:00 (24hr format)

 rtc.setDate(1, 1, 2014);   // Set the date to January 1st, 2014

 pinMode(relaylampu,OUTPUT);

}

void loop() {

t = rtc.getTime();

doorswitchx = digitalRead(doorswitch);

unlockx = digitalRead(unlock);

lockx = digitalRead(lock);

kontakonx = digitalRead(kontakon);

if(kontakonx == 1){

kunci = 1;

rtc.setTime(0, 0, 0);

digitalWrite(relaylampu,HIGH); //lampu off

}

if(lockx == 1){

kunci = 1;

}

if(lockx == 0){

kunci = 0;

}

if((unlockx == 1)&&(lockx == 0)){

  digitalWrite(relaylampu,LOW); //lampu on

  delay(10000); //10 detik

  digitalWrite(relaylampu,HIGH); //lampu off

}

if((doorswitchx == 0)&&(tanda == 0)&&(lockx == 0)){

  digitalWrite(relaylampu,HIGH); //lampu off

  rtc.setTime(0, 0, 0);

}

if((doorswitchx == 0)&&(tanda == 1)&&(lockx == 0)){

  digitalWrite(relaylampu,LOW); //lampu on

  delay(10000); //10 detik

  digitalWrite(relaylampu,HIGH); //lampu off

  rtc.setTime(0, 0, 0);

  tanda = 0;

}

if((doorswitchx == 1)&&(tanda == 0)&&(t.min < 5)&&(lockx == 0)){

  digitalWrite(relaylampu,LOW); //lampu on

  t = rtc.getTime();

  tanda = 1;

}

if((doorswitchx == 1)&&(t.min >= 5)&&(lockx == 0)){

  digitalWrite(relaylampu,HIGH); //lampu off

  t = rtc.getTime();

  tanda = 1;

}

  Serial.print(t.hour, DEC);

  Serial.print("/");

  Serial.print(t.min, DEC);

  Serial.print("/");

  Serial.println(t.sec, DEC);  

}
