I am designing a circuit that requires a flashing LED when performing a wrong sequence. The correct sequence has 2 possibilities. The circuit has 8 switches that initialize D flip flops. The correct sequences are as follows; SW1, SW2, SW3, SW4, SW5 or SW6, SW7, SW8, SW1, SW2, SW3, SW4, SW5. The flashing LED is to be powered by a 555 timer which I already have configured. However for the life of me I cannot figure out how to get the timer to trigger off a wrong sequence. Can anyone help out with this? The requirement to complete the flasher is to use basic logic flip flops or some combination of and/or/nand/nor/xor gates.
I am using multisim for the basic design and then building the circuit with actual hardware.
