Diodes can be used for implementing simple logic gates such as AND or OR combinations. For the AND gate, all inputs must be tied to high, 5V for the output logic high. For OR gate, the output is high if any input(s) are high.

Simple Logic Gates using Diodes
Diodes can be used for implementing simple logic gates such as AND or OR combinations. For the AND gate, all inputs must be tied to high, 5V for the output logic high. For OR gate, the output is high if any input(s) are high.
