INPUT_PULLUP can be used instead of the external resistor.
Would this be difficult to connect to an LCD screen?
We have a tutorial about that here! ua-cam.com/video/s_-nIgo71_w/v-deo.htmlsi=_-oZBgmUT2rvKAgj
which hall sensor will give me logic high at output after detecting by magnet???
You would want a digital sensor for that, not an analog one.
@@Science.Buddies can u tell me , which digital sensor i can use?
In this project: www.sciencebuddies.org/science-fair-projects/project-ideas/Elec_p094/electricity-electronics/arduino-mass-driver#materials we use this sensor: www.amazon.com/dp/B07QS6PN3B?tag=sciencebuddie-20
it's a metal detector!!!!
Not quite - the range is pretty small and it will only detect permanent magnets (or electromagnets). It won't detect ferromagnetic materials that aren't currently magnetized.
