Mailbox Assistant connects to a Arduino (or similar) device located inside of your mailbox and reports a status of the contents. Waiting on an important letter? Arriving home for the day? Or do you have a P.O. Box? Ask the mailbox assistant to check your mailbox, to avoid unneeded trips to your mailbox. The Mailbox assistant uses your email address from your Amazon account to subscribe to the device's messages.
