UPDATED GUIDES – Buttons, Sounds and LCDs for Raspberry Pi #rpi
CircuitPython libraries are now available on all Raspberry Pi Models (v1, v2, v3 and Zero). It does not matter if you have an older 26-pin Pi (v1, v2) or a newer 40-pin (v3 and Zero). We have been updating our older Pi tutorials to be compatible across every released Pi version to date. The most recent guides to be made CircuitPython friendly are:
Playing sounds and using buttons with Raspberry Pi
Use CircuitPython libraries on a Raspberry Pi to trigger audio file playback using tactile button presses. If you have not already used the Raspberry Pi as a input device this guide will show you how to wire up the buttons to the GPIO pins and access their state from a python script.
Adding a LCD to any project immediately kicks it up a notch. This tutorial explains how to connect an inexpensive HDD44780 compatible LCD to the Raspberry Pi using 6 GPIO pins. While there are other ways to connect using I2C or the UART, this is the most direct method that gets right down to the bare metal. The example Python code sends date, time, and the Pi’s IP address to the display. If you are running a Pi in headless mode, being able to determine the IP address at a glance is really handy.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
