Free eBook for LabVIEW Community Edition
LabVIEW Community Edition was released on 04/28/2020.
https://www.ni.com/en-us/shop/labview/select-edition/labview-community-edition.html
The LabVIEW Community edition is free for non-commercial use. For those who use LabVIEW for the first time, the Japan LabVIEW User Group provides a free e-book written by volunteers.
The title of the e-book is "Enjoy Programming with LabVIEW Community Edition". You can learn how to use LabVIEW while running multiple example programs. And enjoy programming.
Currently, we are translating the Japanese version into English, and we are updating the part where the translation is finished and releasing it as an alpha version.
"Enjoy Programming with LabVIEW Community Edition" can be downloaded from the homepage of the Japan LabVIEW User Group.

In Chapter 6 of "Let's Enjoy Programming" with LabVIEW Community Edition, we will build an experimental circuit using easily available electronic components to measure the VI characteristics of LEDs.
An example of regression analysis is shown to organize and understand the experimental data.
In Chapter 4, we introduced an application that allows you to view a spectrogram using a homepage or YouTube as a sound source. Experience LabVIEW data recording and powerful frequency analysis.
In Chapter 4, We configured it so that the state machine could create your own application.

It's fun to see the sound!
LINX is useful when using Arduino like IO in LabVIEW, but sometimes it seems that serial communication is a bottleneck. LabVIEW + LINX cannot be used when it is difficult to make the function for the sensor you want to use by yourself.
In Chapter 7, we will use the sensor used in the "pulse oximeter" called the MAX30102. It is said that the "pulse oximeter" is attracting attention as an effective tool for early detection of pneumonia in people infected with the new coronavirus. The VI to create only measures the heart rate, but it seems that the data of saturation of percutaneous oxygen can be easily obtained.
A little modification of the example program in the MAX30102 Arduino library to output data from the Arduino at 10msec intervals via serial communication.
The LabVIEW program is very simple because it only receives data via serial communication, and you can apply any sensor that can be used with Arduino.
