PWM control

It is also possible to output an PWM signal on the GPIO pins.

To set a certain PWM level:

http://<ESP IP address>/control?cmd=PWM,<pin>,<level>

This feature can be used to dim lights, control (DC)-fan speeds, etc.

Be aware that the direct GPIO has currently an "heartbeat" issue where flickers can occur
