Both methods work and there is one more that also works really well using an IC, there are many simple circuits such as dual AND Gates, 555 timer, and even some purpose made debounce IC's. It keeps the edges fast if thats desirable. Some Families of IC's can't handle slow transition edges and does not tie up the processor.
Nice video, Pico! keep going!😎
Cool! 😃

Can easily see this as a automotive fault creepin up. Will make for a brilliant case study.
