This sketch implements an example of enabling a custom web page |
||||
according to the state of an externally equipped switch. The custom |
||||
web page configures and provides a static IP to the ESP module. |
||||
This example needs to equip an external switch circuit that pulls up |
||||
with a resistor (1K to 10K ohms) and then drops it to GND via a push |
||||
switch to connect to any GPIO of the ESP module. |
||||
