 === Description
 Writes an analog value (http://arduino.cc/en/Tutorial/PWM[PWM wave]) to a pin. Can be used to light a LED at varying brightnesses or drive a motor at various speeds. After a call to `analogWrite()`, the pin will generate a steady square wave of the specified duty cycle until the next call to `analogWrite()` (or a call to `digitalRead()` or `digitalWrite()` on the same pin). The frequency of the PWM signal on most pins is approximately 490 Hz. On the Uno and similar boards, pins 5 and 6 have a frequency of approximately 980 Hz.

+On most Arduino boards (those with the ATmega168 or ATmega328), this function works on pins 3, 5, 6, 9, 10, and 11. On the Arduino Mega, it works on pins 2 - 13 and 44 - 46. Older Arduino boards with an ATmega8 only support `analogWrite()` on pins 9, 10, and 11.
+The Arduino DUE supports `analogWrite()` on pins 2 through 13, plus pins DAC0 and DAC1. Unlike the PWM pins, DAC0 and DAC1 are Digital to Analog converters, and act as true analog outputs.
+You do not need to call `pinMode()` to set the pin as an output before calling `analogWrite()`.
+The `analogWrite` function has nothing to do with the analog pins or the `analogRead` function.

+The PWM outputs generated on pins 5 and 6 will have higher-than-expected duty cycles. This is because of interactions with the `millis()` and `delay()` functions, which share the same internal timer used to generate those PWM outputs. This will be noticed mostly on low duty-cycle settings (e.g. 0 - 10) and may result in a value of 0 not fully turning off the output on pins 5 and 6.
