Usage

LightSensor sensor;

public override Task Initialize()
{
    Console.WriteLine("Initialize...");

    sensor = new LightSensor(Device.Pins.A01);

    var consumer = LightSensor.CreateObserver(
        handler: result => Console.WriteLine($"Observer filter satisfied: {result.New.Millivolts:N2}mV, old: {result.Old?.Millivolts:N2}mV"),
        filter: result =>
        {
            if (result.Old is { } old)
            { //c# 8 pattern match syntax. checks for !null and assigns var.
                return (result.New - old).Abs().Millivolts > 500;
            }
            return false;
        });

    sensor.Subscribe(consumer);

    sensor.Updated += (sender, result) => 
    {
        Console.WriteLine($"Voltage Changed, new: {result.New.Millivolts:N2}mV, old: {result.Old?.Millivolts:N2}mV");
    };

    return Task.CompletedTask;
}

public override async Task Run()
{
    var result = await sensor.Read();
    Console.WriteLine($"Initial read: {result.Millivolts:N2}mV");

    sensor.StartUpdating(TimeSpan.FromMilliseconds(1000));
}
