Hello everyone, I have to make an interface using an Arduino Uno and a LCD screen. I use push buttons to select sub-menus, a SD card to display a list of products from a file and a RTC (DS 1302) to give time and date. The push buttons are connected to pins 2 to 7; LCD screen is connected to pins …

Can't manage to sort a file and display time & date on a LCD screen.
