Amperage Limit for LED Strips #252

Open Fusseldieb opened 6 years ago

Fusseldieb commented 6 years ago

Hey, I'd like to suggest a feature that's not yet present and that I've missed a ton. In FastLED's library you could set a amperage limit for the whole LED strip, and if the LED was using more than the specified amperage, it would lower the brightness a bit. That brightness change was so suttle that you don't even notice it. For example: White would dim a bit to satisfy my 2A limit, but when I use red, it wouldn't dim at all, because it didn't exceed the specification.

On this project you use the NeoPixel library, which doesn't support that parameter and I've burned 3 Buck converters until now (and counting). With FastLED that wasn't a problem, there they were just fine.

Not Sure on this but this might reduce consumption by 50 %

Line 626 - 627

server.on("/get_brightness", []() { String str_brightness = String((int) (brightness / 1.25));

@Fusseldieb That sounds interesting, but this might better be implemented in the animation library and just used be McLighting.
