I was wondering about those same issues.It shows no voltage pin to the 7 segment display, nor does the logic have current limiting resistors. I question the working part.
Is the decimal point being turned on by I3 only?When I test this layout everything works fine except the decimal. The decimal has to work by itself but when I turn it on, other parts turn on also
No, it's supposed to be turned on if the input is not a valid BCD number.Is the decimal point being turned on by I3 only?
At the end but during the building stage make a more useful one which will make your life easier.The truth table listed there is all they gave me to reference off of. In the end my table must mimic that.
