WebA pin object is used to control I/O pins (also known as GPIO - general-purpose input/output). Pin objects are commonly associated with a physical pin that can drive an output voltage and read input voltages. The pin class has methods to set the mode of the pin (IN, OUT, etc) and methods to get and set the digital logic level.

WebInterrupts will be triggered when a signal’s state (LOW/HIGH) changes. There are 2 kind of interrupts: RISING: when the state goes from LOW to HIGH. FALLING: when the state goes from HIGH to LOW. So, basically in your program if you set up a FALLING interrupt, then your program will be notified as soon as the signal goes from HIGH to LOW.
