Looking for cheapest, simplest way to randomly light multiple led's? Prefer not to use arduino or similar. Maybe 555? Answered
I am working on a project to sell which will have multiple led's lit at different times. I guess it would be like those old pictures or posters they would sell that had led's in places where the lights might be in a cityscape (windows of skyscrapers etc.), or the taillights or headlights of a car, or the street lights lining a city block. Since I am wanting to sell these items, I obviously need the cheapest, most efficient way of doing this in order to make a profit. Using an arduino is not how I want to go. I do have some electronic knowledge, however, could use any ideas/ suggestions. Also need ideas on smallest brightest led's available. The led's that are in led strips really seem to be what I would like to use, but don't know if these can be purchased and used individually. Thanks.
