Gotcha, that's what I was looking for, thanks. I haven't gotten the LEDs yet, but the diodes that Chagrin linked pull 30 mA, so I'll probably be dealing with something similar. I looked at the TLC5916 chip, and can't find any mention of how/where to use a resistor for output current, but I'd prefer to do it that way for simplicity. Any insights on how that works?

Fair enough. I have practically no experience with this, so sorry if I'm coming off a bit noob-ish. Is it possible to just split off of the 5VDC power supply that is running the Arduino, and feed the input of the shift registers with that?

So, will the 3v provided on the board be enough? Or is it subject to the same limitations as the outputs?

Cool. Checking those out now. Would the voltage input for the shift register need to come from a different power supply, or would I be able to use the 3v from the Arduino?

So, the shift register actually looks like a really nice way for me to accomplish what I want to do. Basically all lights are on, then they go out in a chase sequence. So, each of my shift register outputs would have a transistor that feeds power to the candles from a separate power source?

So, one of you said resistor, I understand how that works. The other said transistor, which I don't understand. Could you elaborate please? Thanks a lot guys.

I'd like to try using the mega to power about 50 of these types of LED candles: http://www.amazon.com/Lilys-HomeTM-Everlasting-Tealights-Battery-Operated/dp/B00466VDJQ/ref=sr_1_2?ie=UTF8&qid=1358521666&sr=8-2&keywords=led+flicker+candles  So that I'm able to control the power to each one independently. If I just pull the battery and run an output to the power contacts of the candle, will the Mega be able to supply enough power to run these? And be able to power all 50 simultaneously? If not, can anyone point me in the right direction for pulling this off? Thanks
9  Forum 2005-2010 (read only) / Interfacing / Arduino as video player or controller? on: February 27, 2010, 11:40:39 pm
I have no idea whether what I want to can be accomplished with an arduino, or if I need to look for other solutions. Basically I'd like to load video clips onto an sd card or other storage media, and use the arduino to send these clips to an lcd display, skip through the clips, and if possible do some glitchy effects.
  Alternatively, would it be possible to use an external video source and run it through the arduino and use the arduino to do some glitchy effects on the video (frame stutters, rgb seperations, etc.)?
  I haven't gotten my arduino yet, but this project is something I'm going to work on regardless of whether the arduino can do it or not. Any help or references are appreciated. Thanks!
