Add ability to control intensity

[g-ortuno]

I have a candle that I use for testing. Because it's usually on the battery runs out very fast. Could we add the ability to control the intensity so that the battery lasts longer?

I thought it would be as simple as

let [saturation, red, green, blue] = [0xff, 0x00, 0xff, 0x00];
colorCharacteristic.writeValue(Uint8Array.of(saturation, red, green, blue));

but it isn't ;(

Do you have some thoughts on how we could map rgb values to control intensity?

Does changing the saturation affect the intensity?

[beaufortfrancois]

It doesn't from what I've been testing sadly ;(

// These look the same...
colorCharacteristic.writeValue(Uint8Array.of(0xff, 0x00, 0xff, 0x00));
colorCharacteristic.writeValue(Uint8Array.of(0x00, 0x00, 0xff, 0x00));
