MIT Codes

Below are the Arduino codes 

#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); Bluetooth  module connected to 2,3 pins of ardiuno

#define relay1 A1

#define relay2 A2

#define relay3 A3

#define relay4 A4

char val;

void setup() {

pinMode(relay1,OUTPUT);

pinMode(relay2,OUTPUT);

pinMode(relay3,OUTPUT);

pinMode(relay4,OUTPUT);

digitalWrite(relay1,LOW);

digitalWrite(relay2,LOW);

digitalWrite(relay3,LOW);

digitalWrite(relay4,LOW);

mySerial.begin(9600);

Serial.begin(9600);

}

void loop() {

//cek data serial from bluetooth android App

while ( mySerial.available() >0 ) {

val = mySerial.read();

Serial.println(val);

}

//Relay is on

if( val == '1' ) {

digitalWrite(relay1,HIGH); }

else if( val == '2' ) {

digitalWrite(relay2,HIGH); }

else if( val == '3' ) {

digitalWrite(relay3,HIGH); }

else if( val == '4' ) {

digitalWrite(relay4,HIGH); }

//relay all on

//relay is off

else if( val == 'A' ) {

else if( val == 'B' ) {

digitalWrite(relay2,LOW); }

else if( val == 'C' ) {

digitalWrite(relay3,LOW); }

else if( val == 'D' ) {
