Feather HELP!

My ItsyBitsy/Feather stopped working when I unplugged the USB!

A lot of our example sketches have a

while (!Serial);

line in setup(), to keep the board waiting until the USB is opened. This makes it a lot easier to debug a program

because you get to see all the USB data output. If you want to run your Feather without USB connectivity, delete or

comment out that line

Even though this FAQ is labeled for Feather, the questions apply to ItsyBitsy's as well!
