Usage

Hcsr04 hCSR04;

public override Task Initialize()
{
    Resolver.Log.Info($"Hello HC-SR04 sample");

    hCSR04 = new Hcsr04(
        triggerPin: Device.Pins.D05,
        echoPin: Device.Pins.D06);
    hCSR04.DistanceUpdated += HCSR04_DistanceUpdated;

    return Task.CompletedTask;
}

public override Task Run()
{
    while (true)
    {
        // Sends a trigger signal
        hCSR04.MeasureDistance();
        Thread.Sleep(2000);
    }
}

private void HCSR04_DistanceUpdated(object sender, IChangeResult<Meadow.Units.Length> e)
{
    Resolver.Log.Info($"Distance (cm): {e.New.Centimeters}");
}
