 Runs at 3.5V up to 24V. To use connect power to pin 1 (all the way to the left), ground to pin 2 (middle) and then a 10K pull up resistor from pin 3 to power. Then listen on pin 3, when the south pole of a magnet is near the front of the sensor, pin 3 will go down to 0V. Otherwise it will stay at whatever the pullup resistor is connected to. Nothing occurs if a magnet's north pole is nearby (unipolar).

 Hall effect sensors detect whether a magnet is near. Useful for non-contact/waterproof type switches, position sensors, rotary/shaft encoders.

-The purpose of this project is to demo the usage of Hall Sensor. When the magnet is close to Hall sensor, the LED-L on Arduino will turn on, and the LED will turn on when the magnet is removed.

		+	Pin 3 of hall sensor is connected to D12. D12 will detect the voltage level of D12 to judge if there is magnet close to it. The result will be displayed on LED-L which is controlled by D13.
