Beeping Down Counter (All 7400 Hardware)

Postby ThePyroElectro » Thu Oct 20, 2011 5:26 pm

The Beeping Down Counter

One of the most basic circuits in all of digital electronics is the up/down counter with a 7-segment LED display. While you could easily build a similar circuit using all software and a microcontroller, understanding how to build the same circuit functionality entirely in hardware will give you an edge as a design engineer.
