So can anibody help me please ?
thanks a lot
I have a strip of ws2812b's that I can easily drive from my uno, but I can't for the life of me get the nodemcu 1.0 board to run them; at first I thought maybe 3.3v wasn't enough, so I got a logic level converter... still no dice... I can power the uno from the nodemcu and run the leds from there no problem, but as soon as I try to drive the controllers from the nodemcu, nothing happens... it seems like it should be dead simple, but connecting the data pin does nothing... at all... using example code, code I've gotten from github, anywhere... I've even tried the "define"s that denisjoshua above... any help would be appreciated... I'm going crazy
I was assuming I'd need 10. I can't find a 5V power pack but these looked good: https://cpc.farnell.com/pro-power/pp002110/battery-box-3x-aa-waterproof-wired/dp/BT06561
Are there any issues using long DC power extensions, e.g. https://www.amazon.co.uk/Smedz-DC-Power-Female-Extension-Black/dp/B07FNLBBXB/
These are the sort of 5V power packs people use for wearable/mobile projects that have lots of LEDs. Portable Charger Anker Powercore Elite 20000, 20000mAh Power Bank with 3-Port 6A Output, Dual Input and 4A Fast Recharging https://www.amazon.com/dp/B01LQ7MQG6/ref=cm_sw_r_cp_apa_i_m9-FDb5J0WV81
I have one of those Anker battery packs but it seems like it's 6V out, not 5V.
Specifically this one.
It has two USB outputs. I wonder if it would be enough amps to power the 500 LEDs. I guess if I attach female DC sockets I could just try it out.
Does anyone know of a good simulator for FastLED? I don't want to carry my LEDs around with me when I'm coding. I've found a couple but one is just for Linux and the other I don't really understand. I was hoping for something where I could change the pin and it would output to a set of simulated graphics on my Mac.
Sup yall, quick question, not sure if it warrants a reddit post, but are there 12V power supplies anyone recommends? I got JOYLIT 12V 30A PS off Amazon and it has sucked. Could barely rise above 11V brand new and now after a month, it can't hit 10V. The voltage adjust knob does nothing so I'm returning it and looking for suggestions
This is for my project with 7,128 WS2815 LEDs, but right now I just need 1 to test with my model that has 979
Hi all, I have a simple question that I can't find the solution.
I am trying to replace the delay() for something else, but it does not work:
Instead of:
fastled.show()
delay(DELAY_MS)
I try:
if time_now > last_time + DELAY_MS
{fastled.show(); last_time = time_now}
So both codes are executing fastled.show() at the same time, but the later do not show the palettes correct.
Any idea why this is happening?
Hey folks, has anyone worked with marcmerlin's matrix libraries? I'm trying to get these nice Aurora effects working on some WS2812b sticks
If you ask on the Reddit group www.reddit.com/r/FastLED you can also ping marc as u/marcmerlin in your post.

I was thinking something like fill_solid( leds[0,1,2,5,31,32,35].... Would that work?
fill_solid( leds, NUM_LEDS, CRGB(255,0,0) ); // color red
fill_solid( leds, NUM_LEDS, CHSV(0,255,255) ); // color red
fill_solid( leds, NUM_LEDS, CRGB(0xFF0000) ); // color red
fill_solid( leds, NUM_LEDS, CHSV(0,255,255) ); // color red
fill_solid( leds, NUM_LEDS, CRGB(0xFF0000) ); // color red
also, does FastLED support displays like these? https://aliexpress.com/item/32931309452.html
@spookyvision I'm not really familiar with how the different processors are setup to work with FastLED, but here's a tiny bit of a starting point for you. https://github.com/FastLED/FastLED/tree/master/platforms It's possible you might get a bit more help by asking on the FastLED reddit group but I don't think too many are very familiar with this depth of the FastLED library.
@spookyvision Have a look here for more insight into the process of adding support for your M4f. FastLED/FastLED#308
mostly pin mappings then, good
I notice color values like 0,1,1 flicker visibly
