04-FastLED with Arduino Tutorial Introduction - How to Code for RGB LED Strips (WS2812B)

Source code below! Arduino FastLED Tutorial introduces FastLED and provides connection info and programming steps to get a WS2812B rainbow up and running in one episode.

All coding is shown live in Visual Studio Code, and results are displayed instantly on the ChipCam! Carl the cameraman assists.

IP65 Silicon Waterproof version of 5V BTF Light Strip.

Infinity Mirror that we will modify to build our own:

DC Power Connectors to simplify hookups:

That swanky stainless steel USB meter I use:

And a nice non-stainless version at 1/3 the price:

Came for the Microsoft history, stayed for the awesome projects powered by MSFT option FU money. Dude. You're living the dream. Thanks for sharing.

Dave, I would mention that Mark Kriegsman (kriegsman) joined the FastLED project in 2013 and that the library is still actively maintained by Mark and a great group of people. I am really liking this series of videos, great job.

I was just reading your book earlier today and coincidentally googled how to wire a WS2812B LED strip and found your video! Very cool.

[IngoMich]

Man you are badass! Took me a week to find out i can "puzzle" the GBR / RGB stuff. Also the rainbow method is an awesome trick. Your channel is way underrated, keep up the good work!

[riggsron]

It was so simple I had to watch it a couple of times, and I was convinced I was missing something. Great video!

[ralphgibson]

Thanks for a great video, and seeing the microphone is no problem. Thanks also for the great code display, that's so nice and easy to see. Cheers, Ralph 🙂

[Marc_Miller]

The audio in your video is great. I see no problem keeping the mic right there, it's quite unobtrusive.
And the bokeh is great too. :P Really good video and great info Dave. I think Dan would agree.

Excellent!!!! I found using GPIO 23 for LED DATA on my DOIT ESP32 DEVKIT V1 gave low output during reset and avoids full brightness on power-up. I was trying GPIO3 but it comes up as a driver and is high for about 250ms until the pin gets setup, long enough to confuse all the WS2812Bs and set the controls for the heart of the sun.

Hi Dave
Newbi here .
Very helpful and love your banter.
Well worth a subscription.

[paulsharpe]

Hi there the mic is fine in the corner and you don't need headphones I've seen a few of your other videos and I have subscribed keep up the good work

[matt_b...]

Crap. A friend of a friend went down on that dive boat with Dan. Second time I've heard a reference to that tragedy in the past 7 days.

Hey anyway, I'm really enjoying your channel.

Hey - just as a note - if you are like me, and you bought the Heltec (HiLetgo) ESP32 LoRa instead... :)
You will need to set the OLED_RESET (Pin16) to High and add the following code to the void setup() to get results on your OLED display...

pinMode(16, OUTPUT);
digitalWrite(16, LOW); // set GPIO16 low to reset OLED
delay(50);
digitalWrite(16, HIGH); // while OLED is running, must set GPIO16 to high

Hi Dave. I am at the start of my learning to program LEDs, and this is a nice
introduction. Thank you.

[Validole]

Use FastLed inbuilt power limiting. Works and is nice: you tell it your power or current limit, it globally dims the strip to meet it (if you light too many)

[khatlelid]

I'm following along at home.... Christmas presents will be very bright this year. ;-)

[nicholaszammit]

Might I suggest managing your videos in playlists so that one can view this whole series easily? Thanks for the videos!

[kmonty]

You do a great job. Looking to implement this into a Burningman LED bike set up and a staff that also works.

[matthewhall]

I had a Neopixel strip laying around from an old AdaBox and was able to get my project up and running quickly with this guide. Thanks Dave!

You're the man" #1 fun stuff to do"

What is that hexagonal lamp flashing patterns in the background? Have a video on it? Can be seen at 10:50
