# Windows Remote Arduino 

Using an Arduino as an extension of your app on the Raspberry Pi or Windows PC is an exciting way to quickly add GPIO and other interfaces to a UWP app on a device which may not otherwise support them. For example, you can use an Arduino in concert with a Raspberry Pi to perform analog IO, something the Pi lacks in its native GPIO implementation.

Windows Remote Arduino is also an opportunity to play with "big brain / little brain" scenarios where an application on an application processor (PC, Pi, Phone) does all the user interface interaction and network IO, and the little brain (Arduino) does more real-time operations such as PWM (Pulse Width Modulation), pin toggling, and more.

Example using a Bluetooth-connected Arduino

````C#
private RemoteDevice arduino;
private BluetoothSerial bluetooth;

public MainPage()
{
    this.InitializeComponent();

    bluetooth = new BluetoothSerial("RNBT-5A60");  
    arduino = new RemoteDevice(bluetooth); 

    arduino.DeviceReady += Arduino_DeviceReady;
    arduino.DeviceConnectionFailed += Arduino_DeviceConnectionFailed;

    bluetooth.begin();
}

private void Arduino_DeviceConnectionFailed(string message)
{
    Debug.WriteLine(message);
}

private void Arduino_DeviceReady()
{
    arduino.pinMode(13, PinMode.OUTPUT);
    loop();
}

private async void loop()
{
    int DELAY_MILLIS = 1000;

    while( true )
    {
        // toggle pin 13 to a HIGH state and delay for 1 second
        arduino.digitalWrite(13, PinState.HIGH);
        await Task.Delay(DELAY_MILLIS);

        // toggle pin 13 to a LOW state and delay for 1 second
        arduino.digitalWrite(13, PinState.LOW);
        await Task.Delay(DELAY_MILLIS);
    }
}
