यह तीन स्विच को नियंत्रित या Arduino बोर्ड के साथ रिले करने के एंड्रॉयड क्षुधा है।

This is android apps to control Three switches or relay with Arduino board. This is a simple example app to control anything. We give with code to operate and make a tutorial to use and learn about Android and Arduino Bluetooth communication. arduino code:-

---------------------------------------------------------------------------------------------------------------------------------------

char blueToothVal; //value sent over via bluetooth

char lastValue; //stores last state of device (on/off)

int led = 3;

int ledone = 5;

int ledtwo = 6;

void setup()

{

Serial.begin(9600);

pinMode(led,OUTPUT);

pinMode(ledone, OUTPUT);

pinMode(ledtwo, OUTPUT);

}

void loop()

{

if(Serial.available())

{//if there is data being recieved

blueToothVal=Serial.read(); //read it

}

if (blueToothVal=='n')

{//if value from bluetooth serial is n

digitalWrite(led,HIGH); //switch on LED

if (lastValue!='n')

Serial.println(F("LED is on")); //print LED is on

lastValue=blueToothVal;

}

else if (blueToothVal=='f')

{//if value from bluetooth serial is n

digitalWrite(led,LOW); //turn off LED

if (lastValue!='f')

Serial.println(F("LED is off")); //print LED is on

lastValue=blueToothVal;

}

if (blueToothVal=='a')

{//if value from bluetooth serial is n

digitalWrite(ledone,HIGH); //switch on LED

if (lastValue!='a')

Serial.println(F("ledone is on")); //print LED is on

lastValue=blueToothVal;

}

else if (blueToothVal=='b')

{//if value from bluetooth serial is n

digitalWrite(ledone,LOW); //turn off LED

if (lastValue!='b')

Serial.println(F("ledone is off")); //print LED is on

lastValue=blueToothVal;

}

if (blueToothVal=='c')

{//if value from bluetooth serial is n

digitalWrite(ledtwo,HIGH); //switch on LED

if (lastValue!='c')

Serial.println(F("ledtwo is on")); //print LED is on

lastValue=blueToothVal;

}

else if (blueToothVal=='d')

{//if value from bluetooth serial is n

digitalWrite(ledtwo,LOW); //turn off LED

if (lastValue!='d')

Serial.println(F("ledtwo is off")); //print LED is on

lastValue=blueToothVal;

}

delay(1000);

}
