FastLED Basics Episode 5 - Multiple patterns using a timer or button

In the 5th episode of FastLED basics, we look at how run multiple patterns, and change them either on a timer or by pushing a button. We will then look at crossfading between patterns to provide a more professional look. Finally we will see how and why we might use classes to separate our patterns from each other making it easier to add more patterns or edit the code in the future.

I can't rate this little series high enough. Superb set of videos, thank you so much. What I really love is that you can watch them, take screenies, copy some code, and then just play them and listen...it has sunk in that way, brilliant job Scott.

Hey, I'm an architecture student from China designing a temporary architectural/art installation for my graduation project. I just want to let you know that your tutorials are probably helping many people from different backgrounds! Thanks a lot！

[dylanmartin]

Love this series! New to arduino and by far the best tutorials I have found on YouTube thank you for your work and keep it up!

[amarissimus]

This deserves some repetition - by far the best FastLED series. By FAR. Honestly, if you watch this whole series and can't understand the library, you never will. Fantastic stuff. Thanks.

[PJ_Bottoms]

Your videos are only 14 minutes long, but following along and playing with the code i spend over 2 hours on each video....Thank you so much for making this series i love it to death and will have to go back a few times to truly understand everything you have taught here.

Good stuff mate. No timewasting and BS just facts. Love it.

[marcomanfroi]

Thank you for making those tutorials, you are helping me a lot to learn FastLED. Best tutorials online so far

Textbook YouTube video. PURE content. NO filler. Anxiously awaiting more. In the meantime, I'm going to use these models to create an ESP webserver which will drive multiple patterns with user input. This will reduce my coding time by at least 50%, as I am not a coder either ;)

[Karl_Levine]

Great job Scott. Just great.
Bonus greatness points for talking classes here and what they bring in this context.

These tutorials have helped me do exactly what I've needed to do. The button changing the patterns is great. I've been able to do my own show-reel sketch with gradients, rainbows and beatsin8 patterns.

This video would have been very useful to me a few days ago, I made a gift for my girlfriend with this concept, and i did not know how to program, i use the code of the mask you created, thanks for everything

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!

Do you have a patreon or paypal or some other way that I can support you? These tutorials are truly the best that I've ever found for FastLED.

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.

Thanks so much for this awesome series, and please keep it going

[julesmeredith]

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.

[karim]

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!

[PosTMorteM]

Thanks a lot for these tutorials, been very helpful! (enjoy those coffees). Not a fan on commenting, but the effort you've thrown into these videos is amazing and worth my effort on commenting lol. Still on chapter 5, but ideas and questions are arising as I follow through. I hope I can tackle all my coding problems and ideas with this precious info :)

[anindyamitra]

Thanks a lot for releasing this just before diwali, you saved me man!👍🏻👍🏻

[BGJano]

great video and series! Doing my first project with your tutorials! 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!
