Arduino Waveform Generator

Waveform Generator using an Arduino

Waveform generators (also called function generators) are useful for testing and debugging circuits.  I often use them to test the frequency response of electronics components like op amp and sensors.  This waveform generator is powered by an Arduino.  It outputs four waveshapes: sine, triangle, pulse, and saw, each waveshape ranges in frequency from 1Hz-50kHz.  The …
