So after having some fun I decided to get this: http://www.ebay.com/itm/301148837750?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I also got this for the power supply: http://www.ebay.com/itm/251642810484?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
What I would like to do is make some basic chase effects and control all the LED's at a quick pace in order to strobe and some other things to make it go with music. In order to do so I was thinking of controlling it with an arduino receiving update code from my computer via processing or serial and then in turn updating all the LED's. I know 20m is a lot considering how many LEDs there are but what all would I need to make it work? I have the power supply but how would I make that work with the arduino and the strip of LED? If I am going about this the wrong way then let me know. I do not mind going directly from the computer to controlling the LED strips.
