Please help me for source code and circuit about calculator with six button using arduino uno
If i want to select 0-9 and aritmatic operation just input 6 button to do it
Thank you

 

Is this homework?

 

No, this is project

 

Forget about source code for now.
If you have 6 buttons, what are the functions of each of the six buttons?

 

function of button is numeric and aritmatic. for examples when input number 2 so just one press button twice and next

 

0-9 is 10 buttons. What are the other -4 of them? 10-4 = 6 buttons, right?

How do you plan on doing a calculator with only 6 buttons when some of them are arithmetic? You wouldn't even have enough buttons for the numbers even if you use octal numbering system. You would need to do you arithmetic functions by entering the number in binary.

No one can help you if you cannot properly define your requirements.
