Advanced Arduino Telemetry and Data Visualization #ArduinoMonday

upgrdman shared this video tutorial on Youtube!

In this video I show a new version of the data logging and telemetry visualization tool that I have been developing. This tool makes it easy to visualize data received from an Arduino or any other microcontroller or FPGA.

I start with a demo showing an Arduino Uno connected to a microphone amp and microphone. The mic’s waveform is digitized by the Arduino, and shown on screen in four ways: as a simple line chart, as a fourier transform (DFT), as a waveform view (basically a long exposure photo of several DFTs) and as a waterfall view.

The second demo is of an STM32-based balancing robot. I show how the new quaternion visualization works and highlight some of the other new features in this version of my TelemetryViewer tool.

Then I show how to write an Arduino sketch to send your sensor readings to the PC. We go over how to connect to the serial port, define the data structure sent to the PC, and walk through all of the possible charts that can be used to visualize the data.

Finally I walk through the Java and JOGL source code so you can see how it works and modify it to fit your needs.
