Hi Everyone ...
I am first year engineering student. I am given the project:
Key pad door lock has five buttons on the outside and one button on the inside. The outside buttonsare numbered 1 5. When the code 3-1-5 is pressed the lock opens after the last correct digit (gives an opening pulse to the lock mechanism). When the inside button is pressed the lock opens immediately.
Design key pad door lock according to the specification above . Make sure that no other combination opens the lock and pressing more than one key simultaneously does not open the lock.
Since i am very new to this sujbect, I have done the simple combinational Circuit design using Logisim of K-map.
I have problem in making the circuit sequential. I have no idea how to store 3-1-5 input consecutively and only this sequence of number opens the locked door. I am confused where and how do i need to use flip-flops and different states.
I will be grateful if anyone help me .................. I have attached my simple combinational circuit Diagram ...
