analogWrite(pin, value)
Writes a PWM (Pulse Width Modulation) wave at the output of the selected pin.
Parameters
pin - The GPIO pin number.
value - PWM duty cycle. Available ranges between 0 and 255.
Returns
None
Example
Notes
- The default PWM frequency is 490 Hz
- PWM_OUTPUT uses the hardware PWM of the BCM283x SoC.
The available PWM pins are the followings:

12 | YES |
13 | YES |
18 | YES |
19 | YES |
40 | NO |
41 | NO |
