Build A Network Caller ID LED Screen

Caller ID works wonders when you’re trying to dodge telemarketers, but you need to have the phone nearby. B Tod Cox decided to solve that problem with an LED screen you can set up in any room of the house.

The LED screen shows the caller ID of the current or last call, show’s complete or partial text messages, and can be set to show information about calls on your home phone, iPhone, or Android phone. The setup uses an Arduino, an NCIDdisplay LED Matrix Shield, an NCIDdisplay, and many other components, but Cox’s guide explains everything you need and how to put it together.
