I was going through some old notes today. Found cute little piece of the php code. Here’s to try wordpress’ sourcecode tag:

$self = $_SERVER['SCRIPT_NAME'];

if (isset($_COOKIE['style'])) { 
  $stil = $_COOKIE['style']; 
} else { 
  $stil = 'default'; 
}

if (isset($_COOKIE['lang'])) { 
  $lang = $_COOKIE['lang']; 
} else { 
  $lang = 'en'; 
} 

if ($_SERVER['REQUEST_METHOD'] == 'POST' && $_POST['pazi'] == 'sad') {
  setcookie('style',$_POST['izbor'],time()+6000000,'/');
  Header("Location:$self"); 
} 

if ($_SERVER['REQUEST_METHOD'] == 'GET' && (isset($_GET['ln']))) { 
  setcookie('lang',$_GET['ln'],time()+6000000,'/'); 
  Header("Location:$self"); 
} 

Looks like it works, eh? How about some arduino code?

/*
Blink

Turns on an LED on for one second, then off for one second, repeatedly.

The circuit:
* LED connected from digital pin 13 to ground.

* Note: On most Arduino boards, there is already an LED on the board
connected to pin 13, so you don't need any extra components for this example.

int ledPin = 13; // LED connected to digital pin 13

// The setup() method runs once, when the sketch starts

void setup() {
// initialize the digital pin as an output:
pinMode(ledPin, OUTPUT);
}

// the loop() method runs over and over again,
// as long as the Arduino has power

void loop()
{
digitalWrite(ledPin, HIGH); // set the LED on
delay(1000); // wait for a second
digitalWrite(ledPin, LOW); // set the LED off
delay(1000); // wait for a second
}
