Sometimes a 555 timer does not output a great square wave from 0-5 V. In this case, when using it as a clock source for a flip-flop, a bad 555 timer output can lead to missed clock pulses and seemingly strange behavior on the output. To correct this, use one or two Schmitt inverters (7414) …
In digital systems, I teach about a bunch of different hardware solutions that can be used to implement a project. I thought it would be fun (and not to mention, a learning experience for me) to come up with both a combinational logic project and a sequential logic project and implement each one using a …
The purpose of this post is to make the design process of creating printed circuit boards (PCBs) a little less scary. Please note that, as with most of the hobby stuff on my website, I am self taught. This means that I use auto-routing, don’t worry about ground planes, and the most difficult thing I …
