Level Shifting 3.3V microcontrollers and NeoPixels
Level shifters are like little bilingual translators for your electronics!
by John Park
NeoPixels rule! But, they expect 5V logic, which can cause them to act funny when controlled by 3v3 boards, such as Feathers, M0-based Arduinos, Teensy 3, and others. Not to worry! A level shifter can translate 3v3 logic to 5V and get things talking again in no time!
Mystery Box: Crypto Countdown Case
This Cold War-era mystery box's disarm code must be toggled in before the timer reaches zero!
by John Park
Here's a Soviet themed launch-code box, complete with missile switch covered toggles, a Feather with red 14-segment display for the countdown timer, and stress-inducing piezo buzzer. Use it for an escape room, prop, or wedding proposal. Your players, or potential spouse-to-be, will need to enter the correct five-switch sequence to defuse the device before all is lost. (Note: this project is a harmless prop, not an actual bomb.)

Adalight for Circuit Playground
Revisiting a classic project with Circuit Playground
by Phillip Burgess
One of my first projects with Adafruit was Adalight, an ambient lighting effect for media PCs, similar to the Ambilight feature of mid-2000s Philips TVs. Basically, matching what's on the screen to a set of background lights to make the display pop! This pint-sized version of our earlier Adalight project brings easy ambient media lighting to laptops and small all-in-one PCs.
Raspberry Pi RGB LED Matrix Webapp
Control RGB LED panels from a Web application using Raspberry Pi.
by Roberto Marquez
The project shows how to setup a Web application to control RGB LED panels from Raspberry Pi. The Webapp uses an Adafruit RGB LED Matrix HAT and the rpi-rgb-led-matrix C++ library to drive the panels. The Web application is implemented using Java EE.

Light Paintbrush with Circuit Playground
Create beautiful, expressive light paintings using the Circuit Playground for long exposure photography.
by John Park
The NeoPixels can change color based on accelerometer tilt, making it a terrific angle-based brush. The addition of a battery pack for power and a potentiometer for adjusting brightness make this a perfect light paintbrush!
Tent Lantern
For when you don't want to go bump in the night
by Timothy Reese
When I'm camping, it's dark in the tent. I need a small lantern to gently light my tent, pack compactly, and recharge from a travel battery so I don't need to bring alkalines.
NeoAnim: Using Bitmaps to Animate NeoPixels on Circuit Playground
Use this Python script to enable artist-friendly NeoPixel animation on Circuit Playground
by John Park
Animating NeoPixels can be challenging when using purely coding methods. This technique allows you to create traditional animation-style exposure sheets to control the color, position, and timing of your NeoPixel animation on the Circuit Playground.
