We will now replicate the same functionality as our previous GPIOZero example to turn our LED on and off with a button press, only this time using the PiGPIO library. The code for our PiGPIO example can be found in the chapter02/button_pigpio.py file. Please review and run this file now, and confirm that the LED responds to your button presses.
Let's unravel the interesting parts of the code, starting with the GPIO pin configuration for the push button (again, noting that we're skipping sections of code that we've already covered).
