to prevent always blank flashing the pico
GPIO(19) is used to detect, if the system will break
instead of running the MQTT script.
Just use a jumper cable to connect GND and GPIO(19)
or use a switch on these two pins.
* on exit you'll see led 5 times flashing
* on entering the python script led will flash 1 time
