Hi Jan,

For some reason the commands that ArduinoPi sends out to the Arduino are not being executed by the arduino. If I try to turn digital pin 8 High the Arduino does nothing. I know the Arduino is reading the data because I get a successful POST error handle:

{"state":"success","result":null}

I modified the writedigital function in arduino_pi.class.php to troubleshoot the message that it sends to the arduino by var_dumping the $cmd being sent:

            $this->sendMessage($cmd, 0.2);
        echo '<pre>'; var_dump($cmd); echo '</pre>';  <------------I Inserted this
            $this->deviceClose();
            return true;

The var_dump shows that $cmd is equal to this:

string(7) "@8,255:"

This string seems correct to me, but the arduino is not reacting correctly to it. Also, when the arduino receives the command, I think it resets. Do you have any idea on why it would be doing this?

Thanks for posting this library! I believe it is going to be really helpful to my projects!!
