How to Use a Hall Effect Sensor with Arduino (Lesson #31)

Science Buddies Electronics Kit for Arduino: www.homesciencetools.com/prod...
Add magnetic sensing to your next Arduino project with a Hall effect sensor! This video shows digital sensor A3144 and analog sensor A1302. These sensors are used in the following two Science Buddies projects respectively - check them out!

Great tutorial. Straight forward and clear enough to get me where I needed to go.

[@DesertVox]

INPUT_PULLUP can be used instead of the external resistor.

[@GraceMccurdy-uy7qd]

Would this be difficult to connect to an LCD screen?

[@Science.Buddies]

We have a tutorial about that here! czcams.com/video/s_-nIgo71_w/video.htmlsi=_-oZBgmUT2rvKAgj

[@samanttejasr]

which hall sensor will give me logic high at output after detecting by magnet???

[@Science.Buddies]

You would want a digital sensor for that, not an analog one.

[@samanttejasr]

@@Science.Buddies can u tell me , which digital sensor i can use?

[@Science.Buddies]

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

goddamit i bought digital ones i didnt know they existed, i thought all of them were analog (i only knew about them because of a diy video where the guy uses the signal as a no-drift joystick) i really should've seen this video beforehand lol (they were inexpensive but they take SOO LONG to ship here)

[@JASpits]

it's a metal detector!!!!

[@Science.Buddies]

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.
