With CircuitPython, you can read the information from a Nunchuck controller, control servos, and turn pins on and off, so why not combine those and control a laser. Sure, you could always get a regular old laser pointer and just use your hand to move it, but that lacks the fun factor.
This project uses the ESP32-S2 Feather and one of the reasons for choosing it was due to the built-in STEMMA QT port, but another great reason is because of the WiFi support. This means you could expand the project with another ESP32-S2 Feather and control it over WiFi. Try doing that with a laser pointer!
Take the PyLeap!
Send files and libraries directly to your Bluefruit device without a desktop computer! PyLeap is an app for iOS and iPadOS. It allows you to collect complete projects from the Adafruit Learn System, and transfer them directly to your Circuit Playground Bluefruit without opening a code editor or connecting to a computer.
We now the following guides up on the Adafruit Learning System to get you started with PyLeap:
With so many guides on the Adafruit Learning System, some amazing guides of years past get buried and lost. ALS Deep Cuts brings these guides back up to the surface. This week’s guide is from back in 2013.
Want to wow the audience at your next gig? Light up those parties with a 3D Printed, LED sound reactive microphone flag. This project uses a microphone sensor to illuminate a custom 3d printed mic flag. You can design yours, or use our STLs to print and make your own!
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
