for my next project i am looking at creating a multi light display/show. it will consist of 18 (more later) different light sets that play through different sequences. my problem is i dont know how to write a sketch that will allow me to do this. since i am very new to arduino, i only know how to do the digitalwrite then delay type of thing but that would take forever even on short patterns with 18+ outputs. i would use the mega so would have no issues with the number of outputs avalible. im just looking for a quicker way to create the program that will let me do this. is there any programing shortcuts or ways to have it run through a list of numbers that corispond to the bianary value of the ouput or even better a piece of software that would allow you creat the sequences in a visual way?
oh and one more thing, this is going to need to be a standalone unit, it will need to be able to run it all on its own
