Hey guys, haven’t posted in a while (my last project never got finished). But I need your help again!
Basically, I’m building a large ‘light panel’. Here’s a crappy diagram:
The red area is the lit area.
The first problem I have is identifying what LEDs I have. I am taking these from 4 headtorches i had laying around.
They are powered by 3x AA batteries. Here are some photos:
My main question is, what do I need to do to turn this bundle of LEDs (i’m going to remove them from that lame PCB and wire them to wire and spread them out.
I imagine there is some magic way you guys can tell me what power these LEDs use, what resistors i’m going to need etc.
I want to be able to individually control the brightness of any of the LEDs, so i’m guessing i’ll need PWM Multiplexing? (What ever the hell that is).
So what chips am I going to need, and how am I going to hook them up?
(I realize I ask a lot, and I will be googling to try answer some of my questions, figured I’d ask though :))
