I saw the first photo on the tutorial “Input Data on HTML Form ESP32 Wb Server using Arduino IDE” and got very excited!
The photo shows what looks like a mobile phone screen (with 38% charge!) and input boxes for string, integer and float – and this is exactly what I want to do.
I want to input variables (strings and numeric) and commands onto my phone and send them to the ESP32.
However, the later examples seem to show a screenshot from an ordinary computer which suggests that the input is coming from a normal keyboard.
Do you have a way of inputting numbers and/or letters on a mobile?
 
Thank you.
