Hi Scott. Great set of tutorials! Thanks. Have you done anything more with FastLED since you put these out? Any chance of getting a few more detail tutorials showing more advanced ways of using FastLED? Think lots of people would appreciate that. Would love to see some of this running on a faster & less memory constrained micro like the ESP32 or Pi Pico. Would also like to see ideas on how to use audio input and some of the FastLED patterning & class concepts to produce interesting light shows. I'm currently playing around with this using an ESP32 and I2S audio input. Thanks.

[@julesmeredith2042]

Excellent tutorial thank you. I have managed to get my head around using classes and using blends, but (there is always a but!!) cannot fathom how to combine the two. Any chance of a "Beyond the Basics" series please.

Your use of classes is very clever

[@scottstevens7569]

Once again, Very interesting and well presented. Looking into these less documented or exampled functions is a super thing and providing much needed material. Definitely have to try some of these, especially the crossfading as it reminds me of gradient changes that I hadn't considered other methods of applying. Opening my 20year old can of C is sometimes fun, but the smart tricks are long decayed; luckily the bulk of the actual coding is straightforward. Thanks!

Quick question, I'm having trouble keeping the fastLed library and the pattern files working because im having issues with the file location indexing. I have everything including the fastLed library folder in the same location as the codes i want to pattern. Any advice as to how you got it working and in all one location? I even went to file- preferences to change the folder location but still no luck!

[@ScottMarley]

If you're using the Arduino IDE, use the library manager to install FastLED library. Then you don't put it in the folder with your sketch.

This, and I dont want to come over as a sycophant... This is the best tutorial series I have ever seen for Arduino. Arduino doesn't come intuitively to me, so this is pure gold! May I ask whether future series will include - multiple strips? - adding features like -- a sunrise as alarm, ideally using an rtc -- simulating a fire --a microphone or aux input for any musical effects, ideally with an overlay on the current seting, say adding light on with music feature. Thank you very much, looking forward to the upcoming videos. Subbed!

[@ScottMarley]

That's very kind of you to say so :) multiple strips seems to be a much bigger thing than I had thought, so that might we'll come up in future videos.

Hi Scott, thank you so much for FastLED tutorials, incredibly helpful. I'm in the middle of a little project where (based on your tutorials) managed to make the LED strip work. However the project needs two buttons, one button when pressed the LEDs will need to start flashing for few seconds then stop on its own. Second button when pressed will need the LEDs to start flashing the same way like the first button press, but only stop once the button is pressed again. Is there a way to make th is happen?

[@AntonLock]

Wow...these are fantastic thankyou. How would you go about starting with one pattern then moving into a palette blend that keeps looping (but the first pattern only occurs once)??? Cheers

[@ScottMarley]

I'd probably use switch/case statements. Have the initial pattern as case 0, once this pattern is finished (using millis() or another way of keeping track) set it to case 1 to run the rest of the pattern forever.

12:40 the visuals are being called from a while loop, which checks for isRunning == true, but the statement 'isRunning' will keep returning true because its still in the while loop for executing the visuals, and it never gets the chance to even return to the main loop, much less execute void nextPattern() which contains the code for setting isRunning = false

[@ScottMarley]

And yet if you try the code, it works ;) the reason it works is due to the use of the oneButton library. Inside each pattern, we call btn.tick() which checks if the button has been pressed. It is has, nextPattern is called, setting isRunning to false. I hope that helps to explain it.

[@carmatic]

@@ScottMarley ah, yes, I have missed that important detail I have been trying to get FastLED to work on the ESP32, and I was trying to use it's built in touch capacitive pins in lieu of buttons, that's why I have overlooked all the references to buttons in your code

[@cjr5972]

I have attempted to add a fourth piece of code and encountering an odd problem. i’ve changed the three to a four in the button counter. And I have also added a simple fill solid code to set all the LEDs to a certain color. when I had this new fourth animation i can no longer cycle through all of the four options. It will lock up into the fourth and will stop me from cycling back through the other animations. Any help with this would be greatly appreciated thanks in advance.

[@Knittenware]

How could a multi-position rotary switch (not rotary encoder) be used instead of a button to change patterns?

[@ScottMarley]

Wire the switch common to ground, and each contact to a digital pin on the Arduino. Declare each pin as INPUT_PULLUP. In your loop, something like if(digitalRead(pin1) == LOW) { runPattern1(); } if(digitalRead(pin2) == LOW) { runPattern2(); } and so on.

[@atdiscos9800]

Hi Scott, Great video!, i have just started playing all things Arduino and pixel LED, i'm an electronic engineer and have good experience of pixel LED'S, so what i have a couple of questions you may be able to help with, i want to combine the multiple patterns section but to be able to pick this from a single DMX channel received by the Arduino via an RS485 receiver IC. I have seen some videos on how DMX can be received to make digital pins go high when channels are active which is great. But what i would really like is a way to assign this received data level to a pattern. i.e. 0-10% pattern 1, 10-20% to pattern 2, 20-30% pattern 3 and so on do you have any idea if i could run the dmx receive code at the same time to make this possible on one Arduino? this would then allow me to pick the pre-stored pattern in the Arduino from my lighting desk without the lighting desk having to run loads of channels to create the same effect, and if possible i would still like to have the facility to also have a button to change the running pattern as well ( i.e. Arduino goes into stand alone mode when no DMX signal is detected) anyway i'm going to work trying out more of your examples for fun and practice. Many thanks for all your help.

I was thinking of doing something like this but with a knob switch so when it turns on it goes to whatever pattern the switch is set too so if there is a favorite it will turn on to that vs having to hit the button a few times

[@ScottMarley]

Good idea! I guess you would wire each contact on the switch to a digital input on the micro, check which one is active and run that? Or alternatively, wire each contact through a different value resistor to an single analog input and read the voltage to determine which pattern to show. Lots of options!

[@ScottMarley]

Isn't the nano every the same size as the nano? Just buy a nano clone (they're like £3 on eBay!) and go with that. You won't be able to make the every work with FastLED until the developers add support, it's a non-trivial task.

[@chaseallen4352]

That’s true, I already have all these PCBs made with the pinouts matching the every’s and like 6 every’s though. Do you know anything about Adafruit NeoPixel in stead of fast led? That’s what I was using but I don’t know much about the interrupt features like how you have shown with fast led, that’s what was really drawing me into the fast led, especially with changing patterns with a button

[@ScottMarley]

@@chaseallen4352 Interupts have nothing to do with FastLED, and will work with whichever LED library you choose. The neopixel library is very simple compared to FastLED, but much more limited (no wave / blur / noise / timing functions / palettes / blending etc). There are however additional libraries you can use on top of the neopixel library to fill some of the gaps. I'm not an expert in the adafruit stuff though. It totally depends on what your trying to achieve. The every has exactly the same pinout as the nano, so if you did have to fall back to using a nano, you could still use the same PCBs.

These tutorials are incredible! Can you do a tutorial on how to use a sound sensor in conjunction with LEDs? I would love to see how to program LEDs to react to music.

[@ScottMarley]

I don't have a tutorial as such, but it you watch part 1 kzbin.info/www/bejne/oJnchqSua86hras and part 2 kzbin.info/www/bejne/hJnGaoCshK1jfdU this should give you an idea. Or if you want to go more complicated, see my vu meter matrix kzbin.info/www/bejne/g5jLY4qYobRolcU which is more of a tutorial. Or screw all that and just install Andrew Tuline's sound reactive WLED fork github.com/atuline/WLED

Thank you for those great tutorials

[@dvohwinkel]

IMHO and only my humble opinion.. The classes part felt a little out of place.. but it probably is good to get people thinking about it and the benefits it can bring. Love the series and look forward to seeing more. Please don't take my comment as negative. I really like your use of diagrams and real breadboards..

[@ScottMarley]

Don't worry, I know what you mean. The classes stuff is more complex than anything else in this series, so I think that's why it doesn't feel like it fits. I was wondering if I should include it or not, and I decided to do so mainly in case people find code like this online and wonder what on earth it's doing.

[@jacktsonis]

@@ScottMarley I am super glad you included classes. Done well enough to be useful as I go through it a few times playing with my own code while trying to work this out (relative newbie). Big functionality extension!

@@ScottMarley The videos are AMAZING but I didn't quit understand this video (I'm relatively new to Arduino programing) would love some help :P

[@leonarda1973]

I was wondering how to create a routine of different patterns with different periods of time, something like EVERY_N_SECONDS( 5 and 7 and 10). Maybe creating an array like timer[]= {5, 7, 10} and including it into EVERY_N_SECONDS(timer[]). Any tip would be appreciated!!!

[@ScottMarley]

Look at the EVERY_N_SECONDS function here, the one with timingObj as a parameter. That might get you started github.com/marmilicious/FastLED_examples/blob/master/every_n_timer_variable.ino

[@jondanks2000]

Fantastic vid, many thanks.

[@AjdinHaYa]

Really nice tutorial thank you very much

[@jonatanseifert]

Is there a page where all Fast Led commands are listed?

[@ScottMarley]

You can find everything here fastled.io/docs/3.1/modules.html It's not great documentation, but if you know the name of the function you want, you can use the search box. Start by having a look through each section until youget an idea. There are hundreds of functions!

[@limit-less831]

Scott you are a star !!! Thanks to you I have mange to built nice lamp for my little girl, i have make combination with plenty of patterns in separate .h file. I am struggling with one thing thought maybe you could help me or direct me, I am changing patterns with button and let say on case 30 I want all the patters to change after some time. Any chance you could help me with h file ? can i do case inside a case ? or maybe there is simpler method ? thanks a million in advance.

[@anshuljamesofficial6853]

Can anyone help me with the code and want to run twinklefox and pride2015 in a single sketch one after another.

[@baili8654]

Very thanks!

[@leonarda1973]

Cool tutorial!!! Well done!!!

[@coffinsnail6930]

These are so awesome can you make one about alerts on twitch triggering patterns for the lights This way my subs have one pattern and my follows have a diffrent one.

[@arvidbauters]

Brilliant stuff!!!

[@matthiash.454]

But now I think it's great what you can do everything like that

[@ScottMarley]

Thank you for all your comments!

[@rompipelotas]

thank's a lot !!! very very good tutorial !!! Biggest..............

[@ScottMarley]

You're welcome!

[@farlangriffiths9826]

Like the content scott good stuff

[@ScottMarley]

Thank you. Next one will be on its way hopefully within a week. We'll see how work goes.

[@dannysprogis8446]

Brilliant!

[@MOVIMIENTOARTYCO]

Hello! Amazing tutorials, (i love the mask), I'm trying to do a pattern-changing routine at different times( not every 5 seconds). any ideas? thanks. And I love the mask and the irregular matrix!!!!!!

[@ScottMarley]

It depends on exactly what you want to do. It's hard to go through all the code in a comment! You can't use EVERY_N_MILLISECONDS for a variable time, but you can use the normal if(millis() > previousTime + interval) { do stuff }. Of you can be more specific about what you're after I can write up some code or something for you

[@MOVIMIENTOARTYCO]

@@ScottMarley Hi! I want to make a routine for my juggling clubs (just a 30 leds strip), full static colors and gradients and some patterns with movemet, like fire and rainbow, etc. if(millis() > previousTime + interval) { do stuff }, can work! i´ll try, thanks!!!

[@naomimariah8879]

scott U LEGEND

[@ScottMarley]

Thank you, that's very kind! Go make some awesome stuff :)

[@javasyndicate713]

Sir, more focus on coding text when explaining, hard to see small text on my phone :) Nice explained, anw, Thank You

[@ScottMarley]

Thanks for your comment. It's always a compromise between showing enough of the code at once, and enough detail. All the code is available on GitHub if you want to see it more clearly.

[@andakar121]

I'm so happy and grateful to have found your tutorials! I think creating classes for patterns will help me a lot. I didn't follow however, how you go from Fire2012.ino to creating it into Fire2012.h If you can point me to the part of this or other tutorial that shows that I'd be grateful. I've watched all episodes up through 5 a couple of times. Each time I watch them my understanding goes deeper. And how do you get separate tabs in the IDE for each of the included files? Thanks again for all this great info!
