Hello, Forum.
I'm trying to work out a piece of code here:
instead, If I can make it as an input where the user can put his mobile number on a 16x2 LCD and by using 3 or 4 switch buttons as a navigation keys.
Apart from being in the wrong section of the forum , you’re a long way off here…
println() ‘outputs’ a value, while you’re obviously looking for input .
Show us your whole sketch, and how everything is connected up, then we may be able to help.
