To build this example project, you'll be using an internet-connected Arduino board that will send a text message. We've chosen to use:
An Arduino Uno R3
An Adafruit CC3000 WiFi Shield
A USB A - B cable
A push button
A 10k Ω resistor
A half-size breadboard
You'll also need a Temboo account and a Twilio account. To set up your Temboo account (if you don't already have one) you can create one for free here. You can create a free Twilio account here.
Finally, make sure that you have the latest version of Temboo's Arduino library installed; if you don't, you can download it here.
