In Chapter 10, Publishing to Web Services, we created text messages using a technology called Twilio. In that instance, we used Twilio to send text messages when an intruder was detected. In Chapter 11, Creating a Doorbell Button Using Bluetooth, we created a Bluetooth doorbell using the Blue Dot app on an Android phone or tablet. The doorbell sounded a buzzer and gave a little light show on an RGB LED.
For this project, we will combine Twilio with the Bluetooth doorbell, and have a text message sent when someone pushes the Blue Dot doorbell (refer to Chapter 10, Publishing to Web Services, and Chapter 11, Creating a Doorbell Button Using Bluetooth, to familiarize yourself with these technologies).
