What about the following?
A digital signal can be high or low, represented by voltage differences. Positive logic uses high voltage for logic 1 and low voltage for logic 0. Negative logic reverses this. Signals can be active high or active low, based on the logic state that activates them. It is important to note that in embedded Rust, abstractions show the logic level and not the voltage level.
Sorry, I may not have expressed myself clearly. :cry: This question is a bit beyond my abilities. Maybe it's better to keep the status quo.

I find this passage a bit confusing. I think there are three basic concepts here:
This passage seems to confuse these concepts. And I don't think LEDs are a good example (unless a schematic is provided), because they can be driven in both ways. The "active low pin" in the last paragraph is also a strange expression. Can we rephrase this passage?
