Introduction
The ESP module can control things with it's build-in GPIO output pins. We can turn these on or off or we can set these pins to a special Pulse modulated value (PWM output). And it's also possible to send short pulses (single puls) to one of these pins to control specific devices that are switched with a single short high or low signal.
Hardware
It's best to connect a LED to the GPIO to test your setup. You could dim this LED with the PWM mode commands.

ESP Easy
We do not have to select a task to control basic GPIO output.
