It looks like the code bit you posted got truncated. No worries, as you posted the link.

LED, Switch_port,switch_pin,Debounce_time and Switch are defined earlier in the program. Switch_port is the port to which the switch is connected; Switch_pin is the specific pin debounce time is used in the library function "Bounce". Switch is the position/pin of the switch. LED is the position of the LED. The code bit operates as follows.

  • Debounce the switch
  • If the switch is pressed, ~Switch, toggle the state of the LED. Note that when the switch is pressed, it sends a 0 to the pin. Hence, we test for the inverse of switch.
  • Wait for the switch to be released.
  • Repeat (forever)

Any questions?

In the link you provided, there is a detailed description. "Bounce" is a library function; supplied as part if the language for the specific purpose of debouncing the switch. It is represented by the first line of my explanation.
