How Decade Counters Work
In this video, Karen teaches how decade counters work. They are integrated circuits that use logic gates, flip flops, and a clock signal to cascade a high output signal across ten outputs. Decade counters typically may count in one of three binary methods, decade, BCD, or bi-quinary. They can be used to control 7-segment displays, an array of LEDs, and more. Follow along as Karen explains all of these concepts and the internal workings of decade counters.

thats the best explanation of all these pins I ever heard, these different counting methods of decade counters always confused me!
I stuck to the HEF4017 and CD4017 for just that reason, now I can dabble…
Another great episode.
I once used counters to set up a programable pulse generator with frequency and pulse width.
We used this circuit to allow a computer to cycle through a large array of frequencies…
