A simple interface to GPIO devices with Raspberry Pi.
Component interfaces are provided to allow a frictionless way to get started with physical computing:
from gpiozero import LED from time import sleep led = LED(17) while True: led.on() sleep(1) led.off() sleep(1)
With very little code, you can quickly get going connecting your components together:
from gpiozero import LED, Button from signal import pause led = LED(17) button = Button(3) button.when_pressed = led.on button.when_released = led.off pause()
The library includes interfaces to many simple everyday components, as well as some more complex things like sensors, analogue-to-digital converters, full colour LEDs, robotics kits and more. See the Recipes chapter of the documentation for ideas on how to get started.
GPIO Zero is installed by default in the Raspbian desktop image, available from raspberrypi.org. To install on Raspbian Lite or other operating systems, including for PCs using remote GPIO, see the Installing chapter.
Comprehensive documentation is available at https://gpiozero.readthedocs.io/. Please refer to the Contributing and Development chapters in the documentation for information on contributing to the project.
