Turn off this Arduino alarm clock by flipping it over

This DIY alarm clock even senses a user’s presence and saves power when they’re not around.

When it comes to Makers and their alarm clocks, we’ve seen some pretty nifty ideas in recent months. Added to that growing list is the latest project from Devdhar Patel with his clever take on the age-old timepiece.


Chronobot is a wireless analog clock that consists of a TFT screen, an RTC module for keeping time, a 3.3V battery and an Arduino Pro Mini (ATmega328) as its brains, all housed inside a custom 3D-printed case. An embedded sensor allows the device to sense its own orientation, providing users with the ability to turn the alarm on and off by merely flipping it. Impressively, the gadget even detects presence and powers down when no one is around.


“The alarm setting can be changed from the code. The colors can also be changed from the code, only they have to be in 16-bit format,” Patel reveals.
