I'm supposed do this project that indicates the direction of a tape, forward or rewind. four LEDSs are used to indicate according to an input x where x=0 means the tape is forwarded(right to left), x=1 means the tape is rewinded(left to right).
there is suppsed to be delay between the four LEDs, about 0.1 seconds, to show the direction, for example, if the tape was forwarded, the first LED lights, then after 0.1 seconds the second one lights, then the third and the fourth.
how can I create delay??
I'm supposed to use only D latches , edge triggers and NAND gates.
