Breathalyzer Microphone

Step 22: Testing... Testing... Is this thing on?

I found the easiest way to simply make sure that its working is to turn on the serial monitor, wet a napkin with isopropyl alcohol, place the napkin near the windscreen of the mic and to blow. This should increase the resistance on the microphone and make the numbers that you are seeing increase.

If you really want to test it, you are going to need to get some beers and a couple of friends. Monitor their alcohol intake. Vary the rate at which they are drinking. Also, take note of their height and weight to accurately calculate their intoxication level.

Or... you could just bring it to an art opening and see what happens.
