The best air pressure sensor for making a DIY EWI is currently out of stock, like, everywhere. Sigh! So it's a good thing I already have one. The MPX5010GP is the device in question. Connected to the Arduino, I can use it as a mouthpiece for my electronic wind instrument.

My latest YouTube video documents connecting and coding the pressure sensor to turn it into a really fancy whistle. With buttons working and breath working, two of the three Bs are now taken care of. The third B? Why that's building the EWI! But that'll have to wait until the next video.
