if i were using a simple 5mm RGB led with supply of 4V would I still need that IC?
For a 5 mm LED, no driver need. You can use the output from the Arduino

Rreceivers who are indicating they do not need any circuit, only one resistor for LEDs, because the outputs are 12 V.

The ULN2003A is a driver for manage the power RGB led, in the example is a 5W led.
The irremote library support this prortocols :NEC, SONY, RC5, RC6, DISH, SHARP, PANASONIC, JVC, SANYO and MITSUBISHI.
The IR receiver normally are 36 to 38KHz, depend of remote control, but are not critical.

See this project: http://arduino-cool.blogspot.com.es/2012/09/arduino-rgb-led-managed-by-remote.html
I used the IRRemote library and a cheap remote control .

Hello

I just published a project that fits quite what you mention.
Try this: http://arduino-guay.blogspot.com.es/2012/10/reproductor-mp3-con-arduino-i.html



Hope this helps.
