PWM input?

And have you installed the Arduino bootloader?

Swap just the ATmega chip.  If your circuit works, you hooked up your perf board correctly.  If it doesn't, you didn't.

There's nothing extra on the analog input pins of the arduino boards.

You probably need to show a picture or schematic. If everything except analog inpuys works on the perf board check particularly that pin and avcc.

PWM pins have to be outputs to generate PWM!  Have you done a full continuity check?

Then you wired it up wrong.

Many people believe many things for which there is no proof. Here there is proof to say what you believed is not true.

What is your definition of 'everything'?
