Sending "LED OFF" will turn it off. - - Check out the latest Arduino & Temboo examples and support docs at http://www.temboo.com/arduino - - A Temboo account and application key are necessary to run all Temboo examples. - If you don't already have one, you can register for a free Temboo account at - http://www.temboo.com - - Since this sketch uses Twilio to retrieve the SMS, you'll also need a valid - Twilio account. You can create one for free at https://www.twilio.com. - - The sketch needs your Twilio Account SID and Auth Token you get when you - register with Twilio. Make sure to use the Account SID and Auth Token from - your Twilio Dashboard (not your test credentials from the Dev Tools panel). - - Normally, Twilio expects to contact a web site you provide to get a response - when an SMS message is received for your Twilio number. In this case, we - don't want to send any response (and we don't want to have to set up a web - site just to receive SMS messages.) You can use a URL that Twilio provides - for this purpose. When a message is received and sent to the Twilio "twimlets" - URL, it returns a code meaning "no response required." To set this up: - - 1. Log in to your Twilio account and go to this URL: - - https://www.twilio.com/user/account/phone-numbers/incoming - - 2. Select the Twilio number you want to receive SMS messages at. - - 3.
