So..... I am looking to get a set of flat LED lights to go on when I want them to. I was told I may need to use a DMX driver. So here is what I want to happen. I want to make a flat set of 20 led lights in the shape of a square with the lights filling in the square. I want to get those lights to go from one corner to the other in a row so it looks like it is moving, so I need the corner light to go on and then the next one diagonal to go on as the first one goes off and so on, so it looks like it is moving from one corner to the other. I also want to make these lights go on randomly all over this square one at a time. I would like to be able to turn a switch or click a button so in position 1 it would do the line pattern and in position 2 it would do the random lights. Can I make this happen and can I do it using a battery power. Also I need to keep this simple and cheap if possible. I am not a tech person so you may need to talk to me like a 5 yr old. Thanks.
