RGB LED controller chip? Answered

Does there exist an IC, which can flash RGB LEDs? I really like auto-flash LEDs, but I would like to have several LEDs flash (and change colour) in sync. But auto-flash LEDs, have different flash rates. Is there an IC, which can flash several manual control 4-pin RGB LEDs???

im not sure about just an ic, but the system i use is an arduino and a rgb led with a built in microcontroller. The led thing is called a blinkm and costs about $15. You program the controller using the arduino, and there is a graphical user interface to design the blink pattern. the leds are reprogrammable also. I was able to make my blinkm to blink out binary code for ZEROGX... it was pretty tight.

you can find circuit with similar chip in some keychain toys + you get small leds too the chip in there is directly on the board under a splash of plastic and cannot be removed. but you can cut the board around it to have only that part (carefull to not stress the chip)
