WeMos D1 ESP8266: Adding Battery Voltage Measurement to Deauther 2.1.0

Hello, I am not good at programming and maybe someone has done something similar so let me ask here....

I would like to slightly rework the ESP8266 Deauther 2.1.0 <---[url=]https://github.com/spacehuhn/esp8266_deauther/releases
[/url] soft.
In the menu indeks.jpg Download (5.77 kB) instead of the item "CLOCK" I would like to do some battery measurement e.g. just the voltage alone is enough....

The circuit is powered by a 4.8V Lithium-ion battery connected under GDN - and 5V+ (accepts from 3.3V to 5V) I just miss in the software an indication of the battery level, I know there is a possibility for the arduino to show the supply voltage....

You feed a voltage through the divider to the ADC pin, use the analogRead(A0) function, convert the read value to a voltage for yourself and display it. Without a clue about Arduino and ESP8266 programming, you will not do this yourself.
