/* Designed to drive an array of 8 strips of 25 WS2812b RGB LEDs with different display functions
0) Off No settings / no brightness control
1) Real fire No settings - potentiometer #2 immediately defaults to brightness control
2) Color Fire Setttings = goes through the rainbow hues to select the basic flame color
3) Rainbow Fire No settings - potentiometer #2 immediately defaults to brightness control
4) Barberpole No settings - potentiometer #2 immediately defaults to brightness control
5) Rainbow barberpole Setttings = goes through the rainbow hues to select the basic color
6) Rainbow No settings - potentiometer #2 immediately defaults to brightness control
7) Vertical rainbow No settings - potentiometer #2 immediately defaults to brightness control
8) Horizonatl Rainbow No settings - potentiometer #2 immediately defaults to brightness control
9) Heartbeat No settings - potentiometer #2 immediately defaults to brightness control
10) Color heartbeat Setttings = goes through the rainbow hues to select the basic color
11) Lighthouse No settings - potentiometer #2 immediately defaults to brightness control
12) Color lighthouse Setttings = goes through the rainbow hues to select the basic color
13) Color twinkle No settings - potentiometer #2 immediately defaults to brightness control
14) Monochrome Setttings = goes through the rainbow hues to select the basic color
15) White No settings - potentiometer #2 immediately defaults to brightness control
??) Fire flies (Singke or double spinning around)
??) Starry (Twinkles)
??) Matchlight (Fire from initial match strike to dying fire)
2 potentiometers on A0 and A1 provide control over the different display functions
A0 always provide a 'Mode' control defining the general type of animation (Fire, Rainbow, Steady etc...)
A1 provides a 'Settings' control that changes how the different 'modes' behave.
A timed approach enables 2 (more could be implemented if necessary?) different controls with the same potentiometer.
When a new mode is entered, a timer is started to enable the 'Settings' potentiometer to change a functional parameter.
When the 'Settings' potentiometer is stable for at least 5 seconds, it's function changes to and stays as a global brightness control.

//
// This code is the same fire simulation as the original "Fire2012",
// but each heat cell's temperature is translated to color through a FastLED
// programmable color palette, instead of through the "HeatColor(...)" function.
//
// Four different static color palettes are provided here, plus one dynamic one.
//
// The three static ones are:
// 1. the FastLED built-in HeatColors_p -- this is the default, and it looks
// pretty much exactly like the original Fire2012.
//
// To use any of the other palettes below, just "uncomment" the corresponding code.
//
// 2. a gradient from black to red to yellow to white, which is
// visually similar to the HeatColors_p, and helps to illustrate
// what the 'heat colors' palette is actually doing,
// 3. a similar gradient, but in blue colors rather than red ones,
// i.e. from black to blue to aqua to white, which results in
// an "icy blue" fire effect,
// 4. a simplified three-step gradient, from black to red to white, just to show
// that these gradients need not have four components; two or
// three are possible, too, even if they don't look quite as nice for fire.
//
// The dynamic palette shows how you can change the basic 'hue' of the
// color palette every time through the loop, producing "rainbow fire".

//
// This basic one-dimensional 'fire' simulation works roughly as follows:
// There's a underlying array of 'heat' cells, that model the temperature
// at each point along the line. Every cycle through the simulation,
// four steps are performed:
// 1) All cells cool down a little bit, losing heat to the air
// 2) The heat from each cell drifts 'up' and diffuses a little
// 3) Sometimes randomly new 'sparks' of heat are added at the bottom
// 4) The heat from each cell is rendered as a color into the leds array
// The heat-to-color mapping uses a black-body radiation approximation.
//
// Temperature is in arbitrary units from 0 (cold black) to 255 (white hot).
//
// This simulation scales it self a bit depending on NUM_LEDS; it should look
// "OK" on anywhere from 20 to 100 LEDs without too much tweaking.
//
// I recommend running this simulation at anywhere from 30-100 frames per second,
// meaning an interframe delay of about 10-35 milliseconds.
//
// Looks best on a high-density LED setup (60+ pixels/meter).
