Imagine leaving your phone charging in the garage or car while working nearby, with a crucial email from a top employer on the way. You can't afford to miss it.
The LittleBits Smart Home Kit provides a reliable solution. As we've previously covered in our guide on How to turn on your lights remotely with Cloudbit—which demonstrates how this kit creates fully functional smart home setups beyond aesthetics—here's how to craft an unmissable outdoor email alarm.
This setup blends the classic outdoor telephone bell from industrial sites, repair shops, or bus depots with an IFTTT recipe. At its core are the LittleBits modules: USB Power, MP3 Player, cloudBit, and Synthesizer (synth speaker). You'll also need LittleBits shoes (protective enclosures), a USB power adapter, and a large external speaker.
First, select your alert sound.
Choose a fitting MP3: a heraldic chime, guitar riff, or voice announcing "You have new mail." Search online for sound clips or boards to download options. Trim long files using an MP3 editor or Audacity. Check our 7 Audacity Tips for Better Audio Editing on a Budget for pro techniques on cuts, jobs, and crops.
Insert the microSD card into the MP3 Player bit (it ejects via push-pull). Copy the MP3 to the root directory. For best results with microSD cards, see our guide Get the most out of your MicroSD cards. Always safely eject to avoid data issues—our article Do you really need to eject your flash drive (or device) before removing it? explains why.
Lay out the USB Power bit, cloudBit, MP3 Player, and Synth Speaker on a flat surface. Connect them magnetically, plug in the USB power, and test: the MP3 should play in Once Mode.
Ensure cloudBit syncs to your Wi-Fi network (details in our LittleBits Smart Home Kit Review and Giveaway, covering these magnetized circuit-building modules).
Your setup now plays the MP3 through the synth speaker.
Visit IFTTT.com and create an account if needed. Connect the Gmail channel, then add this recipe for email alerts.
Configure for emails from your IFTTT-connected account. Master IFTTT with our Ultimate IFTTT Guide: Use the Web's Most Powerful Tool Like a Pro. Test by sending from a secondary account to confirm the MP3 triggers. Then, target the specific sender you're awaiting.
The built-in MP3 player isn't loud enough for outdoor use. Options: position the project within Wi-Fi range outside, or connect an external speaker via compatible jack—PC speakers, surround sound, or even a PA system work great. Mount larger ones on a wall or window sill.
