You can find the Demo and Slides I presented from last night attached.
The power supply I used was a BK 9205, the DMM was a Fluke_8808A, and the Arduino was an ArduinoMega (its code is also included).
You should be able to implement your own instruments using the same interfaces, add (or replace) your class at the starting array, and have the code work as expected (initialize, set the output, read the voltage[s], close) when you run it.
Another item was brought up that I had forgotten to mention regarding interfaces: If you work toward SOLID principles, correct use of interfaces helps with the D (Dependency Inversion), in that your code no longer depends on a specific instrument or method of performing a function, but instead depends on the interface to that function (these are the inputs, those are the outputs, I don't care how it's implemented), and makes the core parts of your code that much more portable.
Thanks for the reminder, John! This is another important aspect of OO that should indeed have been mentioned last night!
And thank you all for coming, it was great to see everyone!
