Hey guys!! I have a project I am working on that I am making for my nephew. I am hoping to make a wall mounted sign that has backlighting LEDs. I realize that I don’t have any clue where to start for knowing the right now power for these amounts of LEDs. Is there a affordable, safe and adjustable supply for power (either in a case or just as the chip)for this kind of thing? (bonus points if you can point me towards one that has a second knob for my sis/nephew to use to dim the LEDs!) I want to be able to sell things with these in them.
This is the project for reference! (I think I blew the LEDs when I plugged it in )
