RGB 10w led chip sound reactive.

Hi everyone. I am planning to make sound reactive RGB light with arduino. But I dont know where I need to start, and what parts I need use. Probably I need some Mosfet's, Sound Sensor.

Please, could anyone help me ?

If the LED is 10W then you need a constant current drivers for each of the three LEDs.

Next you need something like this http://tronixstuff.com/2013/01/31/tutorial-arduino-and-the-msgeq7-spectrum-analyzer/

So, if I get constant current driver. What should I do next ? I need use transistor to control that led ?

There is no need for a transistor if you get a constant current driver. Get the type you can apply PWM dimming to and simply connect that to the PWM outputs of the Arduino.

Do you know what 10W RGB LED you are going to use, those are not cheap.

Oh, thanks for info.

I order led chip on ebay,
