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 ) {

}
//Relay is on
