Use sequential and combinational digital logic circuits to design and simulate a digital locking system that produces the following:
 Output “1” if the correct sequence of three decimal-numerals is input to the circuit
 Output “0” if the wrong sequence of three decimal-numerals is input to the circuit
 Count how many wrong attempts have been tried,
 Give an alarm after three failures
can any body please help me to design this digital lock(the sequence of input is 850)??
