DIY AC Waveform Function Generator Kit -- The Learning Circuit 92

DIY AC Waveform Function Generator Kit

The Learning Circuit | element14 presents |  Project Videos

 

 

After just learning about alternating current, Karen solders and assembles a function generator kit in order to generate various waveforms. Once complete, Karen connects the function generator to her oscilloscope to see the various square, sine, and triangle waves. Check out the video to see what happens when Karen also connects a speaker and a string of LEDs!

  • Good episode.

     

    I once tested a laser scanner that actually used a mirror glued to a speaker to scan the laser beam at low frequencies. I do not remember the waveform they used, but it could add some interesting capability for your waveform generator to see how each waveform type changes how the mirror on the speaker would change the way the laser spot was moved.
