A realtime battery indicator for your project without extra components or using any analog I/Os.
Battery indicator in my battery-powered projects, but it uses so many custom characters in the LCD and sacrifice analog input for voltage indication and components and connections. So we decided to do it the smart way and push the Arduino to its limits "as we always do" and get the maximum out of it.
