Hi, i'm a student and i heve to make a 4 bits adder/subtractor with a 74LS83 IC i already made this but my problem is that i have to show the result in 2 7 segment display, and i'm having trouble with this because one display, when the result it's greater than 9, i can't make them to do the rigth counting like 10,11,... i'm using a 74ls83, 74ls248, and some basic gates. i've the scheme that i made in circuit maker, if anyone like to take a look, i apreciate.
Just one more question to wire the display i have to use a resistor in the vcc or in data in?
thanks in advance,
