In this chapter, we looked at data collection at the gadget level. We used an Arduino board to build a data collection gadget. We looked at how we can build a simple display using LEDs. We also discussed providing simple input by debouncing a push button. We used Python programs to help us design some of these circuits.
We also used the analog input pins to gather data from an infrared distance sensor. To be sure that we've got reliable, usable data, we wrote a calibration process. We collected that raw data and analyzed it in Python. Because of the sophisticated statistics module, we were able to evaluate the quality of the results.
We used Python to build a linear model that maps the raw measurements to accurate distance measurements. We can use these Python analytical modules for ongoing calibration and fine-tuning the way this device works.
We also used Python to examine the parameters for an EWMA algorithm. We can use Python to explore the weighting factor. It's very easy to process...
