You might receive an error saying you need "NeoPixel_BLV.ino needs to be in a folder named NeoPixel_BLV". You have 2 options.

This will create a new folder and move the sketch into the newly created folder. Click OK than close Arudino IDE. Move the highlighted files and folder into the new folder "NeoPixel_BLV". You can now reopen the sketch and it should compile without issue.

You can also rename the sketch's parent folder to "NeoPixel_BLV". When you open the sketch you won't receive the error.
