![]() After getting the effect right, I went through and tried to optimize a bit, particularly for memory use, to try and squeeze in larger displays on the lesser Arduinos. To simulate the licking flames of fire, I added random "flares" in the fire that rise from the bottom of the display, and also radiate outward, which I think is really the thing that most improves the effect. The simulation does what I think pretty much everyone does at the most basic level: establishes "heat" near the bottom of the display and percolates it up, reducing the heat as you go. That worked famously, so after some tweaking and a couple of hours playing with it on both Arduino and a NodeMCU/ESP8266, I was satisfied (for the moment). But it was still not refreshing quite fast enough for my taste, so I moved off the Adafruit libraries to FastLED. ![]() So when things started to look like they were going to work well, I dug out a Mega 2560, which had enough RAM to manage the entire 44x11 display. The Uno's RAM topped out at about 11x12, meaning I was using less than 1/4th of the entire matrix width available. I started development with an Arduino Uno and the Adafruit NeoMatrix library, and that worked fine as long as I kept the display size down. It works on any LED matrix supported by FastLED. So I ignored all of those other implementations, and just set about failing repeatedly. There's plenty of code available to do this, but I just wanted to figure out for myself how to code a nice-looking animation.
