comparator has a retro to the (-)input
I've built it three times from scratch with the same result every time
that's what i call retro
has a wire from the (-) input to the output through a resistance
I know it has no components, but I assemble it with real components and it doesn't work,
is this acurate?
how can i convert it to binary code?
Do you think that is better to use a ADC IC instead of LM393 comparator?
