Latihan dasaaaaar bangeeeetsssss... < Led berkedip >



void setup() {

pinMode(2, OUTPUT); }

void loop() {

digitalWrite( 2, HIGH);

delay(500);

digitalWrite(2, LOW);

delay(500);

}


Latihan dasaaaaar kedua lampu berjalan
void setup() {


pinMode(2,OUTPUT); pinMode(3,OUTPUT);


pinMode(4,OUTPUT); pinMode(5,OUTPUT);

}

void loop() {


for (int x = 2 ; x <= 5 ; x =x+1 ) {


digitalWrite ( x, HIGH ); delay (200);


}


delay (300);


for (int y = 2 ; y <= 5 ; y ++ ) {


digitalWrite ( y, LOW );


}


delay (300);


}




Latihan dasaaaaar pengoperasian lampu

const int s1 =13 ,s2 = 12 , led = 2;

void setup() {

pinMode(led, OUTPUT);

pinMode(s1, INPUT);

pinMode(s2, INPUT);

}
void loop() {

byte switch1 = digitalRead (s1) ;

byte switch2 = digitalRead (s2) ;

if (switch1 == HIGH ) digitalWrite (led,HIGH);

if (switch2 == HIGH ) digitalWrite (led,LOW);

delay (100);

}

data cadangan


program dengan tambahan limit switch

int nilai;
void setup() {
  pinMode (13,INPUT);
  pinMode (12,INPUT); 
  pinMode (11,INPUT);
  pinMode (10,INPUT); 
  pinMode (2,OUTPUT); 
  pinMode (3,OUTPUT); 
  Serial.begin(9600);}

// the loop function runs over and over again forever
void loop() {
   if( Serial.available() >0 ) {
     nilai = Serial.read(); // Membaca nilai blutut
    if ( nilai ==1 )   digitalWrite( 2, HIGH ); 
    if ( nilai ==2 )   digitalWrite( 2, LOW ); 
    if ( nilai ==5 )   digitalWrite( 3, HIGH ); 
    if ( nilai ==6 )   digitalWrite( 3, LOW ); }

if (digitalRead (13) == HIGH)  digitalWrite( 2, HIGH );
if (digitalRead (12) == HIGH)  digitalWrite( 2, LOW );
if (digitalRead (11) == HIGH)  digitalWrite( 3, HIGH );
if (digitalRead (10) == HIGH)  digitalWrite( 3, LOW );
delay (100) ;

Desain Hardware

alat :
led 1 terhubung ke pin 2
led 2  terhubung ke pin 3
Relay 1  terhubung ke pin 4 ( untuk menggerakkan pintu buka)
Relay 2  terhubung ke pin 5 ( untuk menggerakkan pintu tutup)

Program arduino

int nilai;
void setup() {
  pinMode (2,OUTPUT);
  pinMode (3,OUTPUT);
  pinMode (4,OUTPUT);
  pinMode (5,OUTPUT);
  Serial.begin(9600);
}

// the loop function runs over and over again forever
void loop() {
   if( Serial.available() >0 ) {
     nilai = Serial.read(); // Membaca nilai blutut
    if ( nilai ==1 )   digitalWrite( 2, HIGH ); 
    if ( nilai ==2 )   digitalWrite( 2, LOW ); 
    if ( nilai ==5 )   digitalWrite( 3, HIGH ); 
    if ( nilai ==6 )   digitalWrite( 3, LOW ); 
    if ( nilai ==3 )   digitalWrite( 4, HIGH ); 
    if ( nilai ==4 )   digitalWrite( 5, HIGH ); 
    if ( nilai ==7 ) {  digitalWrite( 4, LOW ); digitalWrite( 5, LOW ); }

    delay (200);
} }

Kelemahan alat yaitu pintu pagar tidak dapat auto stop.
saran tambah sesor limit switch.

Program kedua






int ls1, ls2, nilai ;

void setup() {

pinMode (12,INPUT);

pinMode (13,INPUT);

pinMode (2,OUTPUT);

pinMode (3,OUTPUT);

pinMode (4,OUTPUT);

pinMode (5,OUTPUT);

Serial.begin(9600);

}




// the loop function runs over and over again forever

void loop() {



if( Serial.available() >0 ) {



nilai = Serial.read(); // Membaca nilai blutut



// if (n!= nilai ) { n=nilai ;

if ( nilai ==1 ) digitalWrite( 2, HIGH );

if ( nilai ==2 ) digitalWrite( 2, LOW );

if ( nilai ==5 ) digitalWrite( 3, HIGH );

if ( nilai ==6 ) digitalWrite( 3, LOW );

if ( nilai ==3 ) digitalWrite( 4, HIGH ) ;

if ( nilai ==4 ) digitalWrite( 5, HIGH );

if ( nilai ==7 ) { digitalWrite( 4, LOW ); digitalWrite( 5, LOW ); }}

// }

ls1= digitalRead (12);

ls2= digitalRead (13);

if (ls1== HIGH ) {

digitalWrite( 4, LOW );

}

if (ls2== HIGH ) {

digitalWrite( 5, LOW );

}







delay (200);

nilai =0;

}
Sudah ada limit switch tapi masih bisa buka tutup nyala bersama
