I recently purchased a "Christmas light" led string on Amazon. Its got a little remote that allows different programs of the RGB leds, however, the options are limited. I can set it up so that all the leds are alternating red and green, but it doesn't have an option for fading, twinkling or flashing that I'd like. The led string consists of two wires coming out of the controller, to the first LED, and then 3 wires to each successive led. Without tearing this thing apart, is there anyone that can tell me if it's feasible to put an Arduino on the front end of this string and set up my own code for it? Thanks in advance. . .

Can you post a picture of the LED string showing the controller and the first few LEDs? Also, a link to the Amazon site where you got it would help.

That may be a PWM controller. Not an easy project to decode and mimic its functions
OK, thanks. I read the manual, and it does do some flash functions. Not ideal, but better than nothing. Thanks to everyone for the input!
So there's no blue, right? (it's not RGB).
I'll take a GUESS and say that it probably lights-up red with positive voltage and green with negative voltage (or vice-versa) and maybe yellow with AC.
If that's true, yes it's "feasible", but supplying and controlling positive & negative voltages won't be easy if you are an electronics "beginner".
