Schematics

At Home Circuit

This circuit is used to flash an LED light when your mailbox has been opened and when it is closed which sends an email to you, notifying when mail has arrived

Mailbox Circuit

This is the circuit used in the mailbox connecting the proximity sensors to the particle cloud to notify when the mailbox has been opened and closed.
