hi all
I want design a Voting system using logic circuit to count the number of who vots positively and display using 7-segment desplay and check of number who siad yes?
Thank for all

Latch inputs and feed to shift register. Clock shift register and count number of outputs. display number. Can design the circuit for a fee.

Can tell you don't work for Diebold. The first thing you need to do is make a back door so you can alter the results. Worry about the non-critical items like pretending to count votes later :lol:

ops:
I need a circuit only from switchs,full adders,4-bit full adder,BCD for 7-segment and two 7-segment display.!!?

now, I have problem!!?
One 7-segment display can't show number of 10,11,12..etc
how to design Tow 7-segment ?

This design is unnecessarily complicated. Are you required to use full adders?

ops: :?
yes, required to use full adders,BCD decoder,comparators and Tow 7-segment display !!

comparators because Vots equal or more than or less!!
Tow 7-segment because show 2 numbers
