project for running lots of LED's with least power consumption (LED Driver)

Other Hardware LEDs and Multiplexing
1

hello guys
it's been a long time since my last post but i'd like to ask you about this project of mine
i want to make an LED driver using arduino
it's for driving alot (3-10) of led strips (length over 5m each) which originally runs on 12v
i want to drive those strips using bluetooth and use a good refresh so i cant see thim blink
and i want to use dimming and flickering as well
it's almost a new year eve present :slight_smile:
i will use this project lots of times
should i build it universal from the start ? (to take as many led strips from the start)
or should i change the code a bit for each project (such as one is 3 stips and one is 7 strips)
how hard is it to control this from a mobile app (bluetooth)
any ready projects i can take ideas from ?
i will use mosfets to run LED's
it's making a big billboard sign using led strips only and i want to make it look cool

i'm not so good with multiplexing
thanks for any help
merry christmas :slight_smile:

Nice project! What platform are you using in the mobile phone?

  1. It is mainly your choice. Either way has its pros and cons
  2. You would have to use a bluetooth module for the arduino side of things. And the programming difficulty would depend on the platform.
    3)Here is a nice one using android and MIT's app inventor
