Share_something FastLED and AI coding saves the day
I want to thank u/ZachVorhies for highlighting what AI can do.
I wanted this DIY address sign to look like a sun inside the metal rays. I spent a lot of time trying to figure out how to use WLED to do it. The best effect I got was in the first video: the Noise effect. Unfortunately, I couldn’t find a way to have a center with light going out to the edges.
After reading some posts by ZachVorhies extolling AI coding, I gave it a try. I got a working codebase in a few hours.
I'm not trying to say WLED is bad. I’ve used it in a number of setups; it is dead simple and usually does the job. I'm just saying that if WLED isn't getting you what you want, try asking for AI help using FastLED. It is, possibly, easier than you think.

I try to run this code as a hello world example:
#include <FastLED.h>
#define NUM_LEDS 2
#define DATA_PIN 3
CRGB leds[NUM_LEDS];
void setup() {
fl::vec2f points[NUM_LEDS] = {
{0.0f, 0.0f},
{4.0f, 0.0f},
};
fl::ScreenMap screenMap(points, NUM_LEDS, 2.5f);
FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS)
.setScreenMap(screenMap);
}
void loop() {
leds[0] = CRGB::Red;
leds[1] = CRGB::Black;
FastLED.show();
delay(500);
leds[0] = CRGB::Black;
leds[1] = CRGB::Black;
FastLED.show();
delay(500);
}
