Basic WIFI joystick using ESP32

This is a very basic WIFI joystick using stock rezistive joysticks based on an ESP32 expansion board . It works in my project with an ESP32 driving the MeArm type Robot replacing the Arduino nano. For power an standard 9V battery pack 6 AA is recommended but I noticed that the 5mm round connector has I think a curent limitation , so the "client" won't broadcast unless one of the usb ports of my expansion board is feed thru an adapter.
