LCD Display without button shield

by sballerinaa on Tue Nov 23, 2021 1:32 pm

Hello,
I am working on a project I want to make an interface using LCD display 16 X 2

I wanted to add three buttons to it:
button 1: left
button 2:right
button 3: select

I want it to move the cursor left and right when it be displaying a question and allowing with the buttons to select options.
Example:
lcd.setCursor(0,0)
lcd.print("Do you want help");
lcd.setCursor(16,2)
lcd.print( "yes" , "no");

from here I want to be able to ALLOW the visual to know that it will be selecting yes or no

With a 16x2 character display, your options are somewhat limited.

One option would be to position the cursor at the selection. e.g. Yes No

Another option would be to indicate the selection with something like asterisks e.g. *Yes* No
