 # Pull- Pins
 
-Suppose a pin is configures as an input. If nothing is connected to the pin and the program tries to read the state of the pin, it would need be in a 'floating' state i.e an unknown state. To prevent this, a pull-up or a pull-down state is defined. They are often used in the case of Buttons and Switches.
