Great how-to for a Trinket RGB LED with a natural fire animation from Tim Bartlett!
I’ve been wanting to create a small light with realistic fire animation, so hot off the workbench in time for mid-winter: a flickering LED candle.
Its brain is a programmable microcontroller, running a smart RGB LED via a single data pin, housed in the lid of a jar. I used Adafruit’s Trinket — a tiny, inexpensive board available in 3.3V or 5V flavors….
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.
