First Arduino project : Leds stripes with 2 loops running at a time

Projects Programming

Hi,
i'm currently trying to setup an art project i'll try to resume here :
First it's a tree, lights are hanging from the branches and the tree has to then light from the tom to the bottom. Once the song is over, it goes out bottom to top and then the first lights goes out all at once.
So :
-Put a magnetic trigger on magnetic switch
-music start

  • Some very specific lights go on (only the lights coming on the outside)
    -The led at the top of the tree (number 28 ) lights
    -All the others leds lights in a chain
    BUT
    giving that the top led is n°28 (non negociable), i have to light leds from 28 -50 and 27-0
    and i'm kinda struggling on this one, cause with my code, there not lighting at the same time...

Could you please help me figure out ?

Please remember it's my very first project and i'm not use to code (nor english is my native language but i guess you figured out)

maybe play with the LEDS in a sim..

Your LEDS simmed..

and here's some Async Led ani. to play with..

have fun.. ~q

Oh thanks for the sim ! it will save some time !
i'll try to make a gif soon !

Look at File|Examples|02.Digital|BlinkWithoutDelay to use millis() for timing instead of delay().
