There’s a lot of magic that can happen in a Mason jar. Just think of children or your own childhood memories of collecting fireflies and other insects and putting them in a jar. The display of fire in a jar can be just as magical for both adults and children. This tutorial shows how to use an Adafruit Feather running an Arduino sketch and an Adafruit 8×8 NeoPixel NeoMatrix to simulate fire. Put all of this in a jar and you’ll have something magical to cherish.
The illusion of fire is created using an Adafruit Feather, an Adafruit 8×8 NeoPixel NeoMatrix, and a wide-mouth Mason jar. The inner diameter of a wide-mouth Mason jar is slightly larger than the Adafruit NeoPixel NeoMatrix, allowing the board to just fit inside the jar (Note: the NeoMatrix is too large to fit in a regular-size Mason jar).
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
