Support National Instruments myDAQ as an Input Source
As @qmascarenhas requested, I have investigated the Python binding for National Instruments myDAQ and believe that it can be used as an authentic source for both sensor calibration and experiments.
@qmascarenhas Can you lend me a sensor of any type to test the myDAQ tomorrow?

yes, sure! sorry I missed this ... can you lmk what exactly you need?
For sensing, the myDAQ has analog and digital inputs. I would focus right now on the analog inputs see example1_read_AI_pins.py. You could even use the myDAQ itself ... wire the 5V pwr output to the AI channel, read and log the reading. I could also give you one of the throttles and you can wire it up to the 5V pwr output and measure the throttle output (AI channel - read and log). In fact, this could be something that @HaydenHour should do as an exercise for his work on the E&M Lab Series work for Lab 1.
Can you let @HaydenHour make a pull request to merge his previous work on the pedal first?
@ATATC @HaydenHour you will need to install the NI-DAQmx driver before you try testing. See https://github.com/ni/nidaqmx-python/blob/master/README.rst#getting-started
Btw the read and write functionalities for input and output devices are not yet implemented.

@HaydenHour for testing I would suggest using VS instead of the wrapper that @ATATC has started writing just to make sure we have a handle on how to address the myDAQ. To start, I would wire DGND to AI0- and +5V to AI0+ and then follow the example steps to read the AI0 channel. You should expect to read a float value of around 5. Please drop by rm217 tomorrow to pick up some jumper wires that you can use.
