As a beginner
How can I make a programable arduino without connecting to PC, mobile phone.
I mean. Only control by arrows switch with configurable program inside.
like when we entering setting mode on printer.
i am looking for make auto-plant system that can enter setting and changing inside program as quick and convenience.
i want to make it can change and choosing what option to use like moisture,luminescence,heat,even lifetime cycle.
thanks you a lot.
