I'm trying to build a circuit that will convert decimal numbers into binary with a keypad.
It is no problem as long as the number is a single-digit, but it gets confusing when the user clicked 2 buttons or more.
for example when the user clicked digit number 1 and then 2, the circuit has to multiply the first digit by 10, and then add the 2.
I have circuits that can add binary numbers and multiply them (and I prefer not having any IC's in this part of circuit).
anyone has a suggestion or can reference me to a useful article i can read about it?
Thanks.
