So it's Halloween time and I need a costume so today I printed off a replica arc reactor in plans of making it interactive. I want to write an android app that allows me to pulse all 10 leds at the same time (normally i would think a series connection through the pwm output) but I also want the ability to create a chase sequence and be able to toggle 14 leds individually. I would think a couple shift registers would be the solution to that...I wonder how most easily allow any of the above functions. Any ideas?
