Based on the ARDUINO NANO + 1N4148 circuit solution, mini oscilloscope DIY can be completed at home

In this video, I will show you how to make my own micro oscilloscope at home, it is easy to make, the code is obtained directly on GitHub, I just make a simple tutorial for everyone. What is an oscilloscope? One previously referred to as "oscilloscope", now there are many kinds, such as CRO (for cathode ray oscilloscopes) or DSO (for more modern digital storage oscilloscopes), etc., these mainly because of the increase in oscilloscope Many functions, but the change is not from its Zong, this is an electronic test instrument, which can be shown in a graphical way to display the change signal [voltage] is usually two-dimensional maps that change over time. Other signals (such as sound or vibration) can be converted to a voltage and displayed. Be As in the video above, the oscilloscope displays the change in the calibrated electrical signal, and the voltage and time are as the Y-axis and the x-axis, respectively. You can then analyze the properties of the waveform, such as amplitude, frequency, rise time, time interval, distortion, and the like. Modern digital instruments can directly calculate and display these properties. Initially, the calculation of these values ​​requires manual measurement of waveforms according to the scale built into the instrument screen. The final molded work, very mini, very cool.
