How to make a mini Oscilloscope at home using Arduino Nano

Make your own mini oscilloscope at home. Easy to do !

In this video, I will show you how to make your own mini oscilloscope at home. It’s simple and easy to make. For the purpose of making this project, I had depended on the third party source code, which link is given below. If you have any question or suggestion, please feel free to comment in my youtube video and please don’t forget to like and subscribe to my YouTube channel.

What is oscilloscope?

An ‘oscilloscope’, previously called an ‘oscillograph’, and informally known as a scope or o-scope,CRO (for cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a type of electronic test instrument that graphically displays varying signal [voltages], usually as a two-dimensional plot of one or more signals as a function of time. Other signals (such as sound or vibration) can be converted to voltages and displayed.

Oscilloscopes display the change of an electrical signal over time, with voltage and time as the Y- and X-axes, respectively, on a calibrated scale. The waveform can then be analyzed for properties such as amplitude, frequency, rise time, time interval, distortion, and others. Modern digital instruments may calculate and display these properties directly. Originally, calculation of these values required manually measuring the waveform against the scales built into the screen of the instrument.

Schematics for the project

Note: Make sure all the connections in your circuit are exactly the same as in schematics.
