Reference Material Needs Update

I don't know how this newbie bug made it through - I swear I tested this code:

Anyway - on the "for" reference page.

void loop()
{
int x = 1;
for (int i = 0; i > -1; i = i + x){
analogWrite(PWMpin, i);
if (i = 255) x = -1; // switch direction at peak
delay(10);
}
}

Change the biggest newbie mistake of

if (i = 255) x = -1; // switch direction at peak

to if (i == 255) x = -1; // switch direction at peak

Maybe it's proof no one reads the docs anyway

Fixed.
