I was wondering if it is possible to connect 8 individual RGB led's much like the adafruit strip. I saw the Pumpkin Pi project and would like to build one. I don't have any yellow or red LED's, but have a small stockpile of the RGB's.
I know for arduino I would use 270ohm resistors to RGB cathodes and control each brightness by a scale of
Is there a way to do this on the Raspberry Pi?
So I've been looking into this a little more. I took your guys idea of using the
TLC5940 LED Driver.
So now I'm asking for some help again. I figured 1 long question that eventually solves this is better then a bunch scattered throughout stackexchange. Now comes the wiring part. I'm using an arduino wiring tutorial as a start since I'm in way over my head. I'm also referring to the data sheet. According to the diagram pin
27 or VPRG confuses me. The Arduino diagram has it grounded so I am grounding. . . How do I connect this correctly to the pi? I'm also guessing I need resistors too...
I'm sorry if this sounds really stupid, but I am a true beginner at this stuff. You have to learn to crawl before you can walk.
What do I need to do to correct this wiring diagram (fritzing)?
The wiring fzz file can be downloaded from google here.
Update 2 - after comment
Taking into account some of the answers and comments this would be the wiring diagram then?
330ohm to anode. 2k ohm to pin
20. How does the inputs get from the pi to chip?
