Here at Adafruit, we spend lots of our time deep down in the lowest levels of the libraries that our examples are built on. At that level we can’t assume that any of the software on the device is working correctly. The tools in this guide can help you load and debug the software on a microcontroller. It’s easiest with a development board that has a debug connector or at least a spot for one. Once the software is loaded, you can use external tools to verify that everything is working as expected (or figure out why it isn’t.) The toughest bugs may take a lot of time to figure out or may require plugging and unplugging a cable. Inline switches can greatly simplify this process by using a switch to effectively unplug the cable without the hassle.
As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email email@example.com to let us know about your post so we can blog it up here.
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.
