A little fire for your heart! But there’s no actual flame here, no heat…instead, LEDs and a microcontroller make a virtual flame that dances like the real thing. (In fact it’s playing a tiny video loop of a real candle.)
We planned this animated flame simply as a piece of high-tech jewelry, but other uses are possible…a fire or lantern effect on cosplay props, a safer alternative to having candles on the table or as part of a holiday display, or a unique night light for finding your way to the bathroom at night.
It’s a simple circuit that can be built either as a pendant or as a tabletop piece. Fair warning though: the pendant variant is tricky…it’s a very tight space requiring ace soldering skills and some unconventional methods. As a tabletop piece, perhaps in a glass votive, or maybe you have a cosplay prop in mind, it’s much more forgiving.

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.
