The best FastLed Tutorial EVER! Continue please!

Scott THANK YOU for these. I've been watching them all today without physically practicing, but I'll be going through them all again hands-on. You're doing an incredible job of introducing new basics and then adding relatively simple but extremely practical complications on top. Exactly what I was looking for.

Thank you so much Scott. This is a great and comprehensive fastled tutorial I have ever seen.

Thanks for this series, its perfectly paced and great references. Please continue producing them, i and im sure all that are watching are learning so much.

This video is awesome! I've been using FastLED for YEARS and I've always been apprehensive for the dive into palettes.. but you've done a fantastic job of explaining it! Thank you!

Another great addition to your Playlist. Ill be referencing your videos for a long time to come. Thanks for the time stamps too. That will definitely help in the future viewings!

Excellent across the board; communication skills, video quality, organization, level of detail and explanation, technical accuracy all come together nicely here. Hope you keep making videos.

Thanx for all your efforts Scott. Can't wait to watch your next tutorial for FastLED :)

Just decided to apply leds and fastled to my project and this video is amazing, thank you for explaining every bit and how it works, now i can do what i had in mind, you showed the way!

Most amazing effects on the LEDs. I am a 56 years (young) beginner in the world of Arduino and individually programmable LEDs. Your videos are like learning A, B, C, D.... covering the most basics and fundamentals... Thank you so much. Great help for people like me..

Thanks Scott. This video "FastLED Basics Episode 3 - Palettes" is fantastic. Palettes are obviously the key to making LEDs dance and your instructions make the abstract concept very understandable. The entire "FastLED Basics" series is must watch TV for anyone that wants to understand how to program LEDs. Thanks again.

Super useful, all the tricks and code sources are really appreciated. Thank you

Thank you so much! These helped me out so much in my projects. This is the most helpful series i've ever found, you deserve all the thanks in the world (:

@ScottMarley

2 жыл бұрын

Say we have red, yellow, green, blue in a palette. I think Noblend should display a block of red LEDs, a block of green LEDs etc. Linearblend will gradually blend between the colours, so red blends into yellow, into green etc. However, when I've played with this, it doesn't seem to work. Not sure if I have the wrong idea though!

@@ScottMarley Thanks for your reply. Makes sense. LINEARBLEND confused me, because if the 1st and last color in the palette are not the same, calling up index 240-255, the color starts to blend back to the 0 index position. I did not expect that. Anyway, thanks again for the great videos. I'm learning a lot!

With 300 LEDs in my array the fill_palette fills all with a solid color, is there something else that needs to be done when using more lights? Your videos are amazing!!!!!

Yes, absolutely! You could do something like: CRGBPalette16 myPalette; myPalette[0] = CRGB(255,255,0); ... myPalette[15] = CRGB(169,234,89); Or whatever :) you could go through from 0-15 in a for loop changing each RGB value slowly if you wanted to, use predefined colours or use HSV (although you'd have to convert to RGB I think before you add them to the palette).

Love this video! Is it possible to use paletteknife with a toggle switch? I have been trying to integrate it in another sketch that uses colorpalettes, but it just won't work.

@ScottMarley

Paletteknife just gives you a way of downloading predefined palettes. Once you have your palette defined, you can use it like any other palette. It is of course possible to switch between a palette using a toggle switch. In pseudo-code: if(digitalRead(toggle_pin)) { fill_palette(blah blah)}; else {fill_palette(blah, blah)}. Which part isn't working?

I am really curious about how these leds work . Like with just voltage input how can we controll leds connected in series separately. Please let me know

Couldn't get code at 5:01 to work, had to change your parentheses () framing the palette to curly brackets { } or whatever these things are called. Then had to change "myPal" to "purplePalette" down in the fill_palette line. With these two changes the code worked fine. Very beautiful, in fact!

So im using the palette code but with 300 leds and once it gets to around 45 or more it starts to flicker or kind of stutter any soultion for this? Thanks

So when doing the color palette at the beginning, I set the NUM_LEDS to 20, but it seems to go past that point and statically illuminate the LED's in the gradient, but they don't move. Expected behavior?

QUESTION 2: If I'm undersatnding fadeToBlackBy, it's automatically fading ALL lit pixels to black at once at that time, but the loop goes back and reruns the EVERN_N_MILLISECOND and a new LED is lit with a random palette color. Thus going back to the fade function and it will attempt to fade that pixel to black. I was confused because the function you specify the "leds" and the "NUM_LEDS," and I was expecting some kind of loop function to specify the specific led that just got lit from the above EVERN_N statement.

How would you use a 16 color palette to change the entire strip from one color to another, instead of scrolling across the strip?

@ScottMarley

3 жыл бұрын

It depends on exacatly the effect you are going for. If you wanted it to smoothly change the whole strip from one color to another through the palette, create your palette as usual (let's call is myPal) outside your loop. Also outside your loop: uint8_t index = 0; Then: loop { EVERY_N_MILLISECONDS(30){ index++ } fill_solid(leds, NUM_LEDS, colorFromPalette(myPal, index)); FastLED.show(); } Or something like that. It very much depends on what you're going for. Make sure the last color in your palette is the same as the first color so when index jumps from 255 back to 0 the color doesn't jump also.

Can you help - wanting to use a button to move between palettes, where should the commands go?

That sounds like it might be a voltage issue on the LEDs (or crappy LEDs!). Check with a multimeter at various points along the strip that your LEDs are all getting around 5V. If not, you might have a power issue.
