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.
Each Monday is ArduinoMonday here at Adafruit! Be sure to check out our posts, tutorials and new Arduino related products. Adafruit manufactures the Arduino right here in the United States in cooperation with arduino.cc. We have a huge selection of Arduino accessories and all the code and tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
