SMAHO

SMAHO is an application allow to control you home by arduino or any microcontrollers support serial communication.
you can link you phone and arduino by using bluetooth module like HC-05 or HC-06 or other bluetooth module support serial communication.
SMAHO send letters to switch ON/OFF you device , uppercase to switch on and lowercase to switch off.
example for arduino:

char val; // variable to receive data from the serial port
void setup()
{
pinMode(2, OUTPUT); //
Serial.begin(9600); // start serial communication at 9600bps
}

void loop()
{
if( Serial.available() ) // if data is available to read
{
val = Serial.read(); // read it and store it in 'val'

if( val == 'A' ) // if 'A' was received
{
digitalWrite(2, HIGH); // turn ON the LED
}

if( val == 'a' ) // if 'a' was received
{
digitalWrite(2, LOW ); // turn OFF the LED
}
}
}
' end of code

so A/B/C/D/E/F/G/H to switch on and a/b/c/d/e/f/g/h to switch off.
