Arduino Smart Letterbox

Arduino Smart Letterbox

Never forget to collect the mail ever again with this useful Arduino mail notifier! Using 315MHz wireless radios, Riley Porter has created a system that lets you know whenever the mail arrives. With this system you never have to worry about soggy mail ever again, and can even keep track of the typical times that mail arrives in your letter box. The notifier uses a light sensor to detect when a letter has been received and then transmits a notification to the receiver over a 315MHz wireless signal. To get started on this project check out the following link.

The project is clearly explained and completing it would be a great way to learn more about working with radio communications.

The wireless functionality in this project is based on a 315MHz wireless connection. These types of connections are very common and have the potential to be used in many different projects.
