# Counters

It's already been a year since I first learned the concept of counters.

This is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock signal. See Counters.

In the schematic shown, a 74190 U/D Decade Counter IC is used to generate pulses from 0000 to 1001 (to be converted as 0 to 9) with the clock of frequency 1Hz then a 7447 Decoder IC is used to drive the seven segment (Common Anode) display.
