Program the Circuit Playground Express with MakeCode right in your browser to give you an exciting 10-9-8... countdown clock that plays music and festive lights! Blow on it for zany party horn sounds!

The Circuit Playground Express has a built in infrared (IR) sensor, and it's very simple to decode the signals using CircuitPython, thanks to the Adafruit Infrared library. We'll program the CPX to read IR blasts from the mini remote control and use these commands to change the bright, beautiful NeoPixels. Plus, we'll defuse the light and dress it up with an inexpensive hobby store ornament and festive puff balls!

Feeling the bite of the cold and wind outside? Why not slither indoors and snuggle up with your very own cuddly Python? What? A snake?! Yessssssss, this AdaBox is Python powered.

CircuitPython code reads the Circuit Playground Express's accelerometer to interpret "dial' rotations as you enter your combination! A servo motor unlatches and unlocks the safe when you've entered the correct combination.

This Circuit Playground Express-based, CircuitPython-driven stepped beat generator is an instant classic! Based on the famous Roland 909 beat box, you can use fruit as capacitive touch inputs to program and play sick beats, using sampled audio files.

Use CircuitPython to program your own snow globe that responds to shaking and plays a holiday music and lights show!

You can cut the cord on the CX-40 joystick and enjoy wireless gaming with this classic controller! Using an nRF52 Feather as a BLE input device, you can play games on any iOS device that uses the iCade standard. Or, code it to work with many other systems!

A phone pad button matrix combines with an RGB character display to build a general purpose UI box with lights, sounds, and knobs! Use it for puzzles, data entry, encryption, machine control, games, and more!

An arcade joystick and buttons solder on to the Arduboy's test pads to bring cabinet-sized gameplay to the tiny, open source game machine! These methods can be used for assistive technology as well.

Peltier cooler + Trinket M0 + CircuitPython = refreshing drinks! This project uses a thermoelectric cooling assembly to turn electricity into coldness!! That chill is transferred to your beverage of choice via thermal conductivity, and then transported safely to your drinking glass with a peristaltic pump. Ahhhh.

By embedding a Circuit Playground Express in a UFO made from a kit, or 3D printing, or even craft supplies, you can create an interactive model fit for filming cheesy 1950s sci-fi scenes!

An IR distance sensor, Trinket M0, NeoPixel strip, and AudioFX sound board plugged into powered speakers combine to make a booby trapped candy bowl. The CircuitPython program measures the distance of objects in front of the IR sensor, and changes the LED colors to match. Then, when you get too close, it screams bloody murder!!

These LED rings add a nice touch to the tick-toc clockwork of your costume goggles. Perfect for Halloween and cosplay.

You can frame an LCD panel and mount it vertically to create a spooky, digital portrait, that seems to have an afterlife of it's own, as the eyes subtly move or the expression changes. This digital picture frame is easy to set up, and fun to use to haunt your friends and unsuspecting guests.

You can wire arcade buttons to the Gemma M0 which can be programmed in CircuitPython as a USB HID device (emulating keyboard strokes) to control any iCade compatible game on iOS! Plus, you can build your own stylish, rugged mini table using slotted aluminum extrusions and hardware! And, no soldering is required, just plug and play!
