Change My Mind

It's called walking on Redstone ore with an observer facing the block with the output hooked up to the input on a T-Flip-Flop.

nice

or tripwire

It’s called a skulk sensor in 1.17

or observer

I thought that only saw block updates not people walking

Unless you put an observer under a red stone ore, so when you step on it and it lights up you will get a signal

oh, well, that would be cool

omg i does need to be added
