// Load Driver

// Open a connection to your RTk.GPIO
$GPIO = new GPIO();

// You can specify the serial device explicitly if you have multiple RTk.GPIO's connected to one machine
// $GPIO = new GPIO('/dev/ttyUSB1');

// Disable warnings if required
// $GPIO->setwarnings(FALSE);

// Set the pin numbering scheme we are going to use
$GPIO->setmode(GPIO::BCM);

// Set pin 2 as an output
$GPIO->setup(2, GPIO::OUT);

// Set pin 3 as a high output
$GPIO->setup(3, GPIO::OUT, array('initial' => GPIO::HIGH));

// Set pin 4 as a pulled down input
$GPIO->setup(4, GPIO::IN, array('pull_up_down' => GPIO::PUD_DOWN));

// Set pins 9, 10 and 11 as outputs
$GPIO->setup(array(9, 10, 11), GPIO::OUT);

// Set pins 14, 15 and 18 as out, out, in
$GPIO->setup(array(14, 15, 18), array(GPIO::OUT, GPIO::OUT, GPIO::IN));

// Set pins 2 as high
$GPIO->output(2, GPIO::HIGH);

// Set pins 9, 10 and 11 as high
$GPIO->output(array(9, 10, 11), GPIO::HIGH);

// Set pins 14 and 15 as high and low
$GPIO->output(array(14, 15), array(GPIO::HIGH, GPIO::LOW));

// Set all pins to outputs (BCM mode)
// $GPIO->setup(GPIO::PINS, GPIO::OUT);

// Set all pins to outputs (BOARD mode)
// $GPIO->setup(array_keys(GPIO::PINS), GPIO::OUT);

// Read pin 4
echo 'Pin 4 = '.$GPIO->input(4);

// Wait a second so you can see the output
sleep(1);

// Cleanup
