i m using a arduino uno r3 .
the problem with my board is that no matter what output i send on the pin - 11 , it is giving a const output , somewhere between high and low . i tested it by connecting an LED to it . all the other pwm pins are working fine but not pin =11.
Is this a hardware problem or something is wrong with the comand .
please help me

thanks

How are you sending output on pin 11? What shields, if any, are attached?
