Teaching students about logic gates is often done in two parts, once on the whiteboard for the theory, and again on the breadboard for the practice. [shurik179] wasn’t a fan of the abstractio… ...

Fixed resistors may be used in place of P1 if desired. Figure 2 shows a breadboard of the top circuit shown in Figure 1. Figure 2 A breadboard of the top circuit in Figure 1, which implements YES, AND ...

It’s an excellent way to get started in digital logic or understanding gates, and much simpler than dealing with 74-series chips on a breadboard like many of us might have done, but those logic ...
