How to use RPi.GPIO?
Press the button on your Pi and watch the LED light up on the remote Pi. With no environment variables set, RPi.GPIO is used as the default pin factory. When the button is created , it uses RPi.GPIO to address a local pin. The default pin factory is replaced with pigpio, connecting to a particular IP address, and the LED is created on pin 17, which now refers to the remote Pi.
What is a pigpio library?
One of the supported alternative libraries is Joan 2937’s pigpio library, which supports remote GPIO. This allows you to remotely control the GPIO pins of a Pi over a network. You can control the pins from a PC or Mac, or from another Pi, and even use the GPIOs of multiple Pis within the same script.
How does GPIO Zero work?
The way GPIO Zero wraps around low-level pin libraries is by providing a pin factory. By default, an RPi.GPIO-based factory is used, and when you ask for a pin, the factory gives you a connection to it using the chosen pin library. A pigpio pin factory can be used on its own (simply use the pigpio library instead of RPi.GPIO), but if an IP address is provided too, this can be used to remotely control a Pi’s pins.
