We mentioned previously that the essence of GPIOZero is writing code that deals with devices and components. Well, RPi.GPIO takes a different and more classical approach where we write code that works with and manages GPIO pins directly. RPi.GPIO is a popular low-level introduction to Raspberry Pi and electronics, so you will find many examples using it across the internet.
The GPIOZero documentation has a great section on RPi.GPIO, where it explains equivalent code examples in both GPIOZero and RPi.GPIO. This is a great resource to start learning lower-level pin level programming concepts.
There is also a library named RPIO that was created as a performance drop-in replacement for RPi.GPIO. RPIO is not currently maintained and does not work with the Raspberry Pi Model 3 or 4.
Here are the key highlights of RPI.GPIO in a nutshell:
- Description: Lightweight low-level GPIO
- Pros: Mature library with many...
