I just ordered some neo pixels that I would like to use with two projects. One is a wearable on a hat with a flora. My other project is using an Uno. Are the neo pixels compatible with the Uno? The reason I want to use the Uno is because the project utilizes a Ping(( sensor. The ping requires 5V as opposed to the 3.3 the flora offers me. Thank you for any help you can provide. Have a good evening.
