 For the Circuit Python Parsec today, I wanted to show you how you can play a wave file on the Circuit Playground Express or the Circuit Playground Blue Fruit inside of the Circuit Playground Library, which gives us these really high-level commands that are very consistent and easy to use. So in this case you can see I've got a library and importing. That's the Adafruit Circuit Playground Library importing it as CP. And then the first thing I do is I play a wave file with this simple command cp.playfile and then the name of a wave file that's sitting on the flash storage of the device. So that's what happens when this starts up and I'll demonstrate that in a second. Then in the main loop of the program I am checking for button presses and a switch to be thrown. So you can see here if CP button A that's the button on the left gets pressed then depending on the state of the little toggle switch we play either this one file BP box wave or this other one triode drama wave. And the B button always just plays this desk up dot wave. So what I'm going to do is I'm going to restart the board. I'm just going to press reset and you can hear it do a little sort of Game Boy startup sound. And now I'm going to press the A button. I got a little file there called BP box. Now I'm going to switch the switch to the right and when I press the same button I'm playing this other wave file triode drama. And then the B button here always plays that one little bleepy file. And that is how you can play wave files right on the Circuit Playground Express or Circuit Playground Blue Fruit inside of Circuit Python using the Circuit Playground Libraries play file command. And that is your Circuit Python Parsec.
