I have built this circuit, and I am unsure which pins on IC4, a 4013 D type flip flop, should be grounded.
Unused pins are 8, 9, 10, 11, 12 and 13. Should I ground 8, 9, 10 and 11?
I don't know if just the unused data input pin should be grounded, or the unused clock and asynchronous input pins as well.
Thanks.
