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

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!

INPUT_PULLUP can be used instead of the external resistor.

Thank you so much for this video. I used it to test our Hall Effect sensors and I was able to determine our issues. Again, thank you so much and have a wonderful day.

[adrianinvents]

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

[nicolaslac]

Very nice video, thank you. Also I wonder if it's possible to switch off the hull sensor? In case where we want to use it only when it's needed.

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)

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

[kaskiiiii]

What magnet are you using and how strong it is

[charrenclaire]

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

[samanttejasr]

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

[HKragh]

so after 6 minutes I have already seen three sets of adds (two per set, so six adds in all, each around 15 seconds). Could you dial it down a tad? I mean, I like the content, but... the rate of adds has to be sensible, right?

Would this be difficult to connect to an LCD screen?
