Adafruit CLUE component tester identifying a panoply of components

Описание: A CircuitPython program running on an Adafruit CLUE with some parts from the Kitronik Inventor's kit and two extra capacitors replicating the "octopus circuit" from the component tester found on oscilloscopes. This plots current against voltage which gives quick visual identification of the component. The program also attempts to identify it and quantify significant values from the smoothed version of the graph.

The tester is intended to demonstrate what can be done with minimal external components and an interpreted language. It currently only uses a sine wave for analysis at around 30-40Hz. It works well with resistors between 82 and 82k ohms, capacitors (with some correction) are reasonable between 22nF and 22uF and diodes work well within the 3.3V range. It struggles with inductors - they need to have a high value (maybe over 220mH) and will over-read.
