Easy way to interface Hall Effect sensor to be used later for proximity sensing, speed measuring and switching

This is a fast and straightway tutorial on how to interface you Hall-Effect sensor with Arduino board, here I’m using Arduino UNO as usual. So the Hall-Effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.Here in the media below you can see a simple visualisation of the effect (Source: Wikipedia):

This effect is exploited to detect position, speed, current and proximity sensing, today we gonna use it with a magnet, to detect the magnetic field and check the values given by the sensor.

In the picture below you can see the sensor I’m using, it’s a KY-024, and as you can see that board is pretty much common, it’s used for different sensors.”
