How can I correctly measure battery voltage using the A0 pin on Arduino?
Hello. @aymen ammari is tapping the voltage for two batteries => 1.5 x 2 =3 volts.
I’m confused why is a divider needed? Please correct me if im wrong, @Afuevu
Also @aymen ammari you can tap the entire 1.5 x 5 =7.5 volts directly by using voltage divider like @Afuevu suggested. You can use any voltage divider calculator online for this purpose.
