Sipping Power With NeoPixels
LED smarter, not harder
by Phillip Burgess
For NeoPixel projects, careful planning and software design — instead of brute force — can yield impressive run times even with modest batteries.
Circuit Playground Bike Light
Blinky bikey fun!
by Carter Nelson
Use your Circuit Playground to make a custom safety light for your bicycle. Learn about colors, using NeoPixels, how to create various animations, and how to choose them using button presses.
Circuit Playground Hot Potato
Pass it fast! Don't be the last!
by Carter Nelson
Use your Circuit Playground to make a simple version of this old-fashioned game. Shake it to start a melody, then toss it from player to player. Try not to be the one holding the Hot Potato when the melody stops.

The NeoPix Arcade Kit comes with a preprogrammed Circuit Playground that includes our 1D Pong Game to immediately start exploring basic game programming concepts on the Circuit Playground. The Circuit Playground Board has a host of sensors to create a variety of handheld electronic gaming projects.
Circuit Playground Beep Beep
One beep for yes, two beeps for no.
by Carter Nelson
Inspired by Capt. Pike's famous beeping wheelchair from the original Star Trek series. We look at a simple program that creates yes/no beeps with button presses and use it to provide a basic introduction to a very important programming topic - refactoring.
Circuit Playground Simple Simon
Test your memory skills with a Circuit Playground version of the classic game.
by Carter Nelson
You are presented with an ever increasing sequence of lights (and beeps) that you must repeat. Each time you are successful, the sequence grows by one. How far can you go?
Mystery Box: The Freefall Deck
When this deck of cards is tossed in the air, it reveals a secret audible Morse code message.
by John Park
Perfect for magic tricks, escape rooms, and slightly unorthodox birthday parties -- this seemingly innocuous, sealed deck of cards contains a secret. When the puzzle is solved, the deck is thrown in the air, tossed to a friend, or dropped a short distance. Freefall is detected by the Circuit Playground embedded within, and it beeps a secret Morse code message.
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.
