Adafruit Learning System Weekly Update: Wireless LEDs Edition #AdafruitLearningSystem

This week on the Adafruit Learning System, we published six new guides! Learn how to make a mini LED matrix audio visualizer, learn how to use the ANO directional navigation and scroll wheel rotary encoder, and get started with the new Adafruit IO WipperSnapper system with two fun new guides.

Favorite New Guide

This week my favorite new guide shows you how to make an IoT door alarm without writing any code!

Always running around and forgetting whether or not you shut your door? Connect your Adafruit Huzzah32 board to the internet so you can always know if you left the door open!

In this project, you’ll wire up a reed switch door sensor to a Huzzah32 and then learn how to use Adafruit IO WipperSnapper capability to make a door alarm without any code! WipperSnapper is a really easy way to set up your device to interface with loads of sensors and devices and send it to Adafruit IO. From there, your possibilities are basically endless.

Getting Started with Wireless LEDs


John Park has created a super fun guide to show us how to use these amazing new wireless LEDs from Adafruit to upgrade your tabletop models.

Tiny LED lights that are both wireless and battery-less are wonderful accessories for scale models, LEGO-compatible brick builds, and table-top gaming. This guide shows how you can add these delightful LEDs and their inductive charging coils to your designs.

You’ll also learn how to build a shelf base and back stand to conceal the induction coil.

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 2014.

Shoot powerful LED lights, from your chest!

Build a chest-mounted cosplay project with a 3D printed UniBeam! In this project, we’ll show you how to use 3D printing and electronics to build the infamous repulsion weapon from ironman. This project was built in collaboration with James Bruton from XRobots.

This 3d printed build was made to go inside of James’ Hulkbuster project. The Hulkbuster is a massive Iron Man-inspired suit James is building with 3D printed parts and various other materials. Watch James’ video and checkout his YouTube channel for more details on his Hulkbuster project.

Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world.
