How is the strip wired to your Arduino?Positive wire of the strip is connected to the Vin on the arduino, and negative to the pin 9.
Im powering arduino through the power jack with the 12V adapter.
If you didn't fry your arduino, you definitely fried the pin. If it's not smd, order a new chip. 5m of 3528 requires 12v and draws up to 5A or more depending on what color you have and how many LEDs are populated on the strip. You definitely will need a MOSFET transistor since your pins will only output 5v 40ma. If your chip is smd, or to get by until you get a new one, switch to a different pwm pin, but make sure you wire the MOSFET in before you do it. They are about $2.50 at Radio Shack.
