HI all
I am given an assignment by my lecture. We are using 74LS93, 74LS00 and 74LS32 ICs to build a 60 seconds stopwatch. . I have some problem building MOD-60 counter from 00 - 59 in multisim. I have connect the these two ICs to two 7 segment LED common Anode.
I do not know how to add in stop/start and reset buttons also. The reset button switch will clear or reset the mod-60 counter to 00 when activated. ie, 00 until it is started again through the use of the start/stop switch.
when the mod-60 value is running , activating the start/stop switch will stop the counter at its current count value, ie, 40, which indicates a time lapse of 40 seconds from the start. Reactivating this same switch will cause the mod-60 counter to resume from this previously stopped value.
We are given other F/F IC like 74LS74 and 74LS112
Pls help me!!
thx
