The problem I'm facing right now is that I could not display the Battery Voltages on my OLED. I'm trying to make changes in my code but I couldn't ...
Actually I 'm working on to show the battery voltages wirelessly from the transmitter to the receiver. But first I want to show it using wire as in the circuit diagram.
I'm stuck on my coding and don't know how to display voltages using a string and substring. If this will happen then it would be more precise and easy for me to show the voltages wirelessly as well.
