CC BY-SA Raspberry Pi Foundation Alternatively, you can use add-on boards that provide embedded components on a PCB (printed circuit board), which sits on top of the Pi’s GPIO pins. The GPIO Zero library provides a simple interface to GPIO devices and includes support for a range of components and add-on boards. off ( ) sleep ( 1 ) See my article on GPIO Zero and Raspberry Pi programming starter projects, and see the GPIO Zero documentation for more information. start_preview ( ) sleep ( 10 ) camera.
