Matt Richardson from MAKE presents his take on the traditional CHristmas tree email notifier utilizing the Arduino and the Ethernet Shield. He says: “On a set interval, the Arduino will connect to a PHP-enabled web server which will, in turn, check for new email. The PHP web server will return the count of messages to the Arduino, which will turn on the tree when it sees that the message count in your in box has risen. Thanks to the PowerSwitch Tail, controlling the A/C electricity is a snap.”
