In this video I share an easy to use program for visualizing data received from an Arduino or any other microcontroller or FPGA. This is an update to the program I released a couple months ago. The video starts off with two demos: an STM32-based balancing robot with accelerometer/gyro/magnetometer readings, and an Arduino Uno with potentiometer/light sensor/thermistor readings. After the demos I cover how to write the Arduino sketch, then go into detail about how to use the program, and finally cover how the source code is laid out in case you want to modify it.

The data can be visualized as: line charts (time domain), line charts (frequency domain), histograms, and as simple dials/gauges. The Dial visualization also shows some basic statistics: min, max, mean, and standard deviation.

If you saw the earlier video, here's a summary of changes in this new version:
- Ported to OpenGL (so it's faster and GPU-accelerated)
- Rewrote all charts (no longer using JFreeChart)
- Can rewind/fast-forward by using your scroll wheel.
- Can zoom in and out by using your scroll wheel while holding Ctrl.
- Can change display scaling (font sizes and line thickness) by using your scroll wheel while holding Shift.
- All data is now logged to a "log.csv" file so you can perform more advanced analysis if needed.
- Individual charts can now be removed by click their "X" icon at the top-right corner.
- Axis autoscaling is smoother.
