Mass production and led's and arduinos? Answered
I'm interested in making something that will have several led's that I would like to flash randomly and some flashing slowly, some fast, etc.. Some with the "fade in/ fade out" kinda deal (sorry, don't know the terminology). Anyway, I'm in the process of learning all about the arduino and I'm just beginning. What I would like to know is, say I figure out how to make these led's do what I need them to and I make up one "unit" and I put it all together etc.; will I have to buy and use an arduino for every single one of these? That would get very expensive. It's kinda like those pictures I've been seeing lately for Halloween/ fall/ Christmas that have led's flashing at different times, and some come on slowly, and then fade out slowly etc.. Or anything really maybe like those little rubber balls that have flashing led's in them. How do they accomplish this? Do each of those pictures have an arduino in them or is it a matter of "programming" some kind of cheaper "chip" and using it in each project? Like I said before, I don't know the terminololgy. Just looking for most economical way of accomplishing this on several different projects. Thanks so much for any help from anyone!!
