Hi,
I'm designing a circuit to check 13 switches (a panel of machine)
I want to make a circuit that can keep the history of pressed switch
show by 13 led lights.This is to make sure I check them all.
When check again I can press reset all light turns off.
I found that 74HC74 D-flip flop would be suit, but I have to use many 74HC74.
Is there a better method by using only few ICs.
Thank you.
