Who could POSSIBLY DISLIKE THIS? This is gold, thank you dude my struggle finally ENDS!

It is also possible to achieve this by using pinMode([pin#], INPUT_PULLUP);
It eliminates having to set the pin to high.

Can this be used with timers and interrupts I want to use an Arduino on a car 12v system so when the key is turned in the door this starts a timer to run something in the car for a set time then turn off?
Love your channel I watch it all the time you are a good teacher Bob UK
