Examine simple waveforms with the Arduino-powered notscilloscope

Next in our line of interesting Arduino-based test equipment projects is the "notscilloscope" by Augusto Campos. This is a neat way to display the amplitude of a signal over time - just as you could with an oscilloscope, however at a slower speed. However this is still a neat way to not only practice your Arduino skills but also understand the basics of how an oscilloscope works.

The notscilloscope can measure waveforms that fall between zero and near the operating voltage of the Arduino or compatible board being used, with the user being able to adjust the centre of the display and also the default amplitude - and an "auto" button can quickly optimised the display of currently-measured data. Check out the following video for a neat demonstration:

For more information and the Arduino sketch, visit Augusto's github page. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.

If you're looking for a neat and colourful display to use with your Arduino or Raspberry Pi - consider our 128x128 pixel OLED Module. With a diagonal size of 1.5" and 16,384 colours to select from, so almost anything is possible. Furthermore there's a microSD card socket, and removable tabs on each side which can hold LEDs and buttons:

And using the module is made simple - we have tutorials and drivers for both the Arduino and Raspberry Pi platforms - great for experimenters or those who use both systems. Furthermore, check out the forum where members are already creating modified drivers to rapidly increase the display speed. For more information including our Quickstart guides - and of course to order - visit the OLED Module product page.
