NEW GUIDE: Python Debouncer Library for Buttons and Sensors #AdafruitLearningSystem #Adafruit #Python #CircuitPython @Adafruit

Python Debouncer Library for Buttons and Sensors

A new guide in the Adafruit Learning System today! Python Debouncer Library for Buttons and Sensors helps you cleanly detect switch state changes with no spurious noise detections.

We use switches a lot in our projects. Pushbutton switches, slide switches, micro switches. We also have touch sensors, light sensors, sound sensors, and many others.

These physical devices are messy. The change from one state to the other (e.g. pressing or releasing a button) bounces back and forth before settling into the new state. You can see this in the oscilloscope trace (above).

This guide introduces the adafruit_debouncer library and it’s Debouncer class. It starts with the basic usage and proceeds to more advanced capabilities.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
