#073 QuadNOR

Demonstrates simple cascading NOR gate logic with the 74LS02 and an Arduino

Here’s the quick demo of the circuit in action:

Notes

See the NOR7402 project readme for more detail on the 74LS02. This is a simple extension of the NOR7402 circuit that cascades 2 NOR gate into 1, with the resulting logic table:
