4-bit Breadboard Calculator
In this video I demonstrate how my 4-bit Breadboard Calculator can be used. It is a 4-bit adder/subtracter/multiplier that in slow mode shows all multiples in the multiplication process. I had great joy designing and building it myself. (And I am more proud of the calculator than the quality of this presentation, but hopefully you will get a good idea of the project.)
If you are interested in more details how it works, you can se my outlines of the project, documented while building (comprehensive but not pedagogical) – maybe it can give you some inspiration to build something of your own: https://drive.google.com/file/d/1ZUet...
God bless!
