littleBits Projects: SMS Doorbell + Answering Machine

This is part of an on-going series of posts about littleBits projects. littleBits is available in the Adafruit store – Base Kit,Deluxe KitSynth KitSpace Kit, Arduino ModuleArduino Starter BundleSequencer Module, and Cloud Starter Bundle. This project was made using the new Smart Home Kit.

Receive a text notification when someone rings your doorbell. Respond by playing back a recording to let them know you are on your way. Elevator music anyone?! 

Whether you are in the backyard gardening, over at the neighbor’s house, or listening to music at full blast, you will always know when someone is at your door. Install this littleBits doorbell outside your home, and never miss a ring.

How it works:

When pressed, the button module on the Doorbell Answering Machine sends a signal through the cloudBit to IFTTT, which is set (via the SMS channel) to send you a text message [i.e. Knock knock! Someone is at the door]. IFTTT (If This Then That) is a service that lets you connect to different web apps through simple conditional statements. With a second IFTTT recipe, you can respond to the text message [i.e. #onmyway]. This will trigger the cloudBit in the Doorbell Answering Machine and activate a sound clip on the MP3 player to play out on synth speaker.

The cloudBit gives you the power to design and build your own internet connected devices, enabling you to design products/projects that are specific and relevant to you. For more project ideas check out our Projects Page.
