ARDUINOArduino is an open-source electronicsprototyping platform based on flexible, easy-to-use hardware and software. It's intended forartists, designers, hobbyists and anyoneinterested in creating interactive objects orenvironments.

PHP - SERIAL PORTS+ Just streams- Console commands for configuration
WINDOWS- fread() blocks until it gets data.

EVENT LOOP
JAVASCRIPT EXAMPLEvar e = document.getElementById('output');var counter = 0;var interval = window.setInterval( function() { e.textContent = e.textContent + counter.toString() + ', '; counter++; }, 1000);
PHP EXAMPLE$loop = Carica\Io\Event\Loop\Factory::get();$loop->setInterval( function () { static $i = 0; echo $i++; }, 1000);$loop->run();
PROMISESThey describe an object that acts as a proxy for aresult that is initially unknown, usually becausethe computation of its value is yet incomplete.
JAVASCRIPT EXAMPLEjQuery .get('hello-world.xml') .done( function (xml) { alert('loaded.'); } ));
PHP EXAMPLE$mysqlOne = new Carica\Io\Deferred\MySQL(new mysqli('localhost'));$mysqlTwo = new Carica\Io\Deferred\MySQL(new mysqli('localhost'));$time = microtime(TRUE);$debug = function($result) use ($time) { var_dump(iterator_to_array($result)); var_dump(microtime(TRUE) - $time);};$queries = Carica\Io\Deferred::When( $mysqlOne("SELECT 'Query 1', SLEEP(5)") ->done($debug), $mysqlTwo("SELECT 'Query 2', SLEEP(1)") ->done($debug));Carica\Io\Event\Loop\Factory::run($queries);
EVENT EMITTER$stream = new Stream\File('c:/tmp/sample.txt');$stream->events()->on( 'read-data', function($data) { echo $data; });$stream->events()->on( 'error', function($error) use ($loop) { echo $error; $loop->stop(); });
