    Hi there,

    I am trying to build something that would implement a similar usage of an rgb LED strip and would love to join the many people that have already commented in receiving the code! Please could you send it to me ?

    Many thanks and great tutorial!

    Hi Justin, I am starting a computer engineering course at my school and would like to try building this. I have everything already except the LED strip, but that is easy to come by. Can you also if possible send me the programming (PICBasic or even in a text file) so that I can get my students to perhaps just program one sequence? This is VERY COOL!!! email:jbiro@cogeco.ca

    Hey! I was asked to do a simple pic project for school and this is great, but I have to understand and explain how the code works and I see you only posted the .hex file, could I get the original code please to razielconz.7@gmail.com? You'd help me out a lot!

    Also, do you think something similar could be done to drive an RGBA luxeon-like LED?

    can this code be put on a pic 16f627-04/p chip? it has 8 legs but im sure I could put it in the circuit if the code would work.
