Logical guessing game circuit

This circuit is the logic guessing game circuit use the digital ICs as base of projects. They are used for playing, with 2 players, the first will set logic, and second guessing logic.

The code in this circuit is 4 switches.

If a player can guess the code exactly as planned, will have the alarm sound and LED light up.

The player is a winner, but unpredictable if no sound comes out, and all LEDs will go out, those who Set code is a winner.

How it works
In the circuit, there are 8 switches include of 2 set,
first S1, S3, S5 and S7 to setting code,
and second S2, S4, S6, S8 are used to selects code.

Then this logic from the switch will through IC1/1 and IC1/2.
The output of IC1/2 is “1” and drive LED lights up, because both input logic same the code is selected.
If we can choose code same 4 set, will have logic “0” at output of IC3/4, to the sound generator circuit.
They include IC4/1 IC4/2, R1, C1 and drive to a loud speaker.

The parts you need
IC1: CD4049, CMOS Hex Inverting Buffer/Converter
IC2: CD4070, CMOS Quad Exclusive-OR Gate
IC3: CD4011, Quad 2-Input NOR Buffered B Series Gate
IC4: CD4001, Quad 2-Input NOR(NAND) Buffered B Series Gate
LED1-LED4: LED color as you want.
SW1-SW8: SPDT- Single-pole, Double-throw
0.25W Resistors
R1, R3: 470 ohms
R2: 100K
C1: 0.01uF 50V Ceramic capacitors
Speaker 8 ohms.

How to builds

The circuit we can assemble on the universal PCB and install in the versatile Box neatly. The box should have a long look, and Should concealed switches are used to select the code, To protect, the other one can see.
