In the middle of this is the littleBits Smart Home kit, specifically the USB power, MP3 Player, cloudBit and synth speaker modules (also known as bits). You’ll also need some shoes (for the littleBits, not your feet) and the USB power adaptor, as well as a large external speaker.

Before you get started, however, you’ll need to choose just how you would like to be alerted to your Very Important Message.

Choosing an MP3 for Your Alert

You’ll need an MP3 file for the alert, so choose something suitable. It might be a heraldic chime, guitar chord, or something else recognizable. Alternatively, you might opt for a pseudo AI solution, one that declares to all and sundry that “You’ve got mail”.

But where can you find a suitable MP3 file? A browse of the web should reveal sound clips and sound boards that you can use to download something suitable.

It’s Not Loud Enough!

No doubt you’ve noticed that the MP3 player module isn’t quite loud enough to let you hear the alert outside. You have two options here: take the littleBit project outside with you (ideal if you are in range of your wireless Internet connection) or attach a loudspeaker.

Naturally you’ll need speakers with a compatible jack, so if you don’t have anything on hand, use a standard surround sound or even PC speakers. Depending on the size, these might be dangled out of a window or even fixed to a wall. In fact, if you have a PA system that you have access to, you might even connect the littleBits smart home project into this…
