Never be late again with the S.M.A.R.T. Alarm Clock


This DIY Internet-connected alarm clock automatically sets itself based on your calendar. 


Have you ever slept through a crucial meeting, missed a flight or showed up late to an exam due to a faulty alarm? Fear no more as the S.M.A.R.T (Setup for Meetings, Appointments, Reminders, and Tasks) Alarm Clock is here to solve all of your problems! Designed by Adafruit’s Tony DiCola and recently featured on MAKE: Magazine, the connected DIY alarm clock sought out to provide users with the ability to enjoy a more restful sleep knowing they’ve solved the nightmare of regulating their alarms.

The S.M.A.R.T. Alarm Clock uses the dual processor-based Arduino Yún. While one processor runs an embedded version of Linux and is connected to the Internet via Wi-Fi or Ethernet, the other processor utilizes the same chip as the Arduino Leonardo (ATmega32U4), thereby enabling the Yún to work with most Arduino shields and accessories.

By using the Arduino Yún, the bedside gadget can talk to complex web services with the Linux processor, and interface with hardware — an LCD touchscreen — on the second processor. The DIY device can sync with your Google Calendar, contacts and e-mail through the Temboo platform, an Arduino-friendly development tool that streamlines access to a variety of web services.

In addition to having both a Google and Temboo account and the Yún with a power adapter, the project calls for a microSD card, a TFT touchscreen Arduino shield, and a USB speaker. The TFT shield is tasked with displaying the clock interface, while the USB speaker sounds that alarm.

The advantage to a device like the S.M.A.R.T. Alarm Clock is that you no longer have to stress about making sure your alarms are correctly set for AM or PM, or are designated for certain days of the week. The clock’s web communication, facilitated by Temboo, assures that you will never miss a beat (or a meeting!) again. The homemade gadget can even pleasantly (or unpleasantly) wake you up to your own MP3 when receiving an important e-mail from a co-worker or relative.
