Stack Cloud Shield on your Arduino, connect it to Twine, and get email, texting, calling, and more in a jiffy. With Cloud Shield, you can add the ability to trigger any Twine output from your Arduino sketch with three lines of code, so you can focus on your idea and not debugging networking code. It has two capacitive pads for easy input with your fingers or conductive objects, and an LED to let you know when it's been triggered.
Includes an Arduino library and a 10' cable to connect the shield to your Twine. (Twine and Arduino not included.)
