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.

Schmitt trigger for cleaning up noisy or slow-rising digital signals

  A Schmitt trigger is a circuit that converts an analog input signal into a digital output signal with hysteresis. It's characterised b...
