Since my last Adafruit Learning System update, we published quite a few new guides. Learn how to create a Macro Pad with giant switches, create a Nunchuck controlled laser cat toy, make a Trinkey true random number generator, and more!
Favorite New Guide
This week my favorite new guide shows you how to make a Nunchuck controlled laser cat toy
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:
- PyLeap Tone Piano for Circuit Playground Bluefruit
- PyLeap MP3 Playback for Circuit Playground Bluefruit
- PyLeap WAV Playback for Circuit Playground Bluefruit
- PyLeap Button Controlled NeoPixels for Circuit Playground Bluefruit
- PyLeap NeoPixel Light Meter for Circuit Playground Bluefruit
- PyLeap Touch NeoPixel Rainbow for Circuit Playground Bluefruit
- PyLeap NeoPixel Sound Meter for Circuit Playground Bluefruit
ALS Deep Cut
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.
Build a sound reactive LED microphone flag
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!
