Netduino in distant motion

Testing some alarm-related components (from left, motion sensor and distance sensor).

(Note the obligatory burn mark on the protective pad.)

To show how little code is involved, this is it (as far as a Q-n-D prototype goes).

Note that the distance sensor is non-linear. I haven’t added compensation for that yet. Note also that I intentionally don’t use a namespace. That’s to make the latter files project independent. The same code would apply to the original Netduino and Netduino Mini.

Program.cs

using System.Threading;
using Microsoft.SPOT;

public class Program
{
    public static void Main()
    {
        while (true)
        {
            LedStatus.status = ProtoBoard.motion;
            Debug.Print(“Motion: ” + ProtoBoard.motion + “, Distance: ” + ProtoBoard.distance);
            Thread.Sleep(1000);
        }
    }
}

LedStatus.cs

using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware.NetduinoPlus;

class LedStatus
{
    private static OutputPort ledstatus = new OutputPort(Pins.ONBOARD_LED, false);

    public static bool status
    {
        set { set(value); }
    }

    public static void set(bool state)
    {
        ledstatus.Write(state);
    }
}

ProtoBoard.cs

using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.NetduinoPlus;

class ProtoBoard
{
    private static InputPort pinMotion = new InputPort(Pins.GPIO_PIN_D11, true, Port.ResistorMode.PullUp);

    public static bool motion
    {
        get { return !pinMotion.Read(); }
    }

    private static AnalogInput pinDistance = new AnalogInput(Pins.GPIO_PIN_A0);

    public static int distance
    {
        get { return pinDistance.Read(); }
    }
}
