Hello,I hope this is a simple question...I am a visual artist and I embed digital photo frames to play videos in my sculptures. The problem is, is that no digital photo frames that I can find play video right away on start up...you always have to press a series of buttons to get the video going.What I did in the past is just soldered onto the buttons and extended them so that you didn't have to reach into the sculpture to press the button and get the video going. But I'd like to use an Arduino to send a signal to the button to press it. So say I need to press one button, wait a few seconds and press it again, is this is simple as making a digitalOut and setting it to HIGH, delaying, set it to LOW, then setting it to HIGH and LOW again? Would it be even easier(cheaper) to just program a smaller AVR chip to do this, if I really wanted a bare bones setup? There's probably some stuff with voltage that I don't understand so anything you can help me with is much appreciated!Thanks so much for any feedback!
thanks for the help! Lefty, do you know a good schematic anywhere for wiring up that relay? I would still use a tip120 or some sort of transistor, no? does this circuit look good? http://www.flickr.com/photos/anachrocomputer/3242387876/in/photostream/ it's good to know that i can drive the relay with the arduino...having three wall worts for one video would be a little ridiculous...
