We r making a random number generator. The timer ic makes the 4029 counter 'count'. But when we remove the clock input from the 4029 ic it is still counting. Can anyone tell us a method to make the counter stop and display the last number it counted?
Can you please post the circuit you are using? If the clock signal is removed I don't see how the counter can continue to up or down count sans clock? Also:
The counter is advanced one count at
the positive-going edge of the clock if the carry in and preset
enable inputs are at logical ``0''. Advancement is inhibited
when either or both of these two inputs is at logical ``1''.
If you flat out removed the clock (as in cut the wire); it may be counting noise. I would suggest a pull down (or up) to ensure a stable signal. Or try what Ron said.
