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

[@adrianinvents]

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

I am trying to trade a glove with a Hall effect sensor and connect it to a python game how can I track the glove with the sensor

[@adrianinvents]

@@Gotcha_again You will probably need an Arduino that pulls in the data. And then a python library that connects you to the Arduino. I would ask ChatGPT. That's how I created my hardware/software setup.

[@DesertVox]

INPUT_PULLUP can be used instead of the external resistor.

[@sensorycircuits1338]

Super clear explanation. Thank you.

[@kaskiiiii]

What magnet are you using and how strong it is

[@charrenclaire1984]

Can I have a speaker coded to output recorded audio when it detects a certain magnetic strength?

[@Science.Buddies]

An Arduino allows you to link any input to any output like a motor, LED, or buzzer. We have our own tutorials on buzzers that can make basic beep/chirp sounds or play simple tunes, but not one about playing recorded audio files - you would need to ask about that in the official Arduino forums or try searching online.

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)

[@SENANURÇETİN-d6d]

What should be the magnetic field strength? (I want to use a Rodin coil to create a magnetic field.)

[@GraceMccurdy-uy7qd]

Would this be difficult to connect to an LCD screen?

[@Science.Buddies]

We have a tutorial about that here! kzbin.info/www/bejne/qZCQn3ydpJxkldksi=_-oZBgmUT2rvKAgj

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

[@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.
