Negative pulses advance the counter. A Reset is high.

Included the 4017 triggering on rising or falling pulses and

a 4017 counting four

Conut the times a nerf gun fires and make it so it only fires three times... I'm a 4 year old with knowledge of circuitry don't judge me T_T

he he he It's probably over kill cus I only need it to count to three but I guess my question was really what pins do what. I understand what a binary counter does I just can't figure out what to connect to witch pin...

I get that 12 of them are out puts but what do the other four do?

It is a counter that counts up to 12 binary places.

Printers use them to tell where the print head is.

CNC lathes use them to tell where the tool post is and so on.

See the logic and output timing.

Use it to divide by 2 raised to the 12th power or less.

Yeah, I just extract the part number and get the data from the horse's mouth.

Saint Patric never visited your land.

I remember at a highway rest stop there was a warning sign about leaving the tarmac because several people expired from injected venom.
