Hello togehter, This is my first post so be patient with me. First of all I wanted to say this is just to know if it is possible or feasable to do with an Arduino and what components I would need for it. And if you want you can give me some tips on the Code too. So lets get to the meat of it: Li…

OK, sorry, I did forget you exact problem. Another glance, off to the beach just now, but You call strip.show every time you loop, but you only change the strip during the 1000 ms service cycle. And not every time even then. So… please try changing the logic so it only strip.show()s on the same r…

Depending on your skill level, it’s either easy, or a learning curve. Before you start, figure out how you’re going to power the LEDs… Using a canned library, declare and initialise an array of all the LEDs you’re going to use (3x8 bits per WS pixel) The a background function will ‘pump’ the LED …

[image] pikdizzl: Is this possible? Yes. [image] pikdizzl: could you kind of hint me in the right direction You need two concepts. First is the state change detection , you can find an example in the IDE under file-> examples -> 02.Basics The next concept is also under the same menu…

Wow thanks for the fast feedback! If I would guess the state change direction is the one i'm missing atm. Controlling the strip itself with a button is not really a problem. At this point I can press the button. The LED turns on and then after 20 seconds turns off again. If I press the button agai…

No i didnt, because its a mess :slight_smile: but here you go In this case the LED goes red and not turn off, but that doesnt matter i guess. #include <Adafruit_NeoPixel.h> #define PIN 6 Adafruit_NeoPixel strip = Adafruit_NeoPixel(20 , PIN, NEO_GRB + NEO_KHZ800); int i; unsigned long ontime; u…

You will need to keep track of the time that each LED. You could use millis(), the number of milliseconds since reset or power on. Or you could use a different length of time more convenient as a unit. Below I suggest using minutes. But you need to keep all those times, and check them to see if th…

Thanks will try this tomorrow. Seems really helpful!

[image] pikdizzl: How can I now know which LED to turn off 40 min later. I would use a timer library like TimeObj.h . It would be a lot cleaner than using millis() in our code. You would set up a timer for each LED, and start the timer when the LED is turned on. When the timer expires, turn t…

Libraries have their place. I do not think it is worth the time in this case. I put my ideas into the OP’s code, and made a few adjustments. There is one call to millis() at the top of the loop. Everything else is just code, idiomatic code from examples like “blink without delay” &c. I believe t…

hey thank you alot! I made it work :slight_smile: . One question I have is,how can I substract 1 minute from every timer in my array. I dont seem to be able to make a for loop work. and if I want to handle 100 LED's at once its annoing to copy every line. #include <Adafruit_NeoPixel.h> #define P…
