Alarm clocks are cheap and abundant, but they’re pretty boring. If you want to make your own, Instructables user Paranoid Legend shows you how to build one with an Arduino.

In this project, PCF85063ATL CMOS Real-time Clock (RTC) is used as the time generator. This provides year, month, day, weekday, hours, minutes, and seconds based on a 32.768 kHz quartz crystal. A ...

You'll need an Arduino, of course, and you'll also need a pair of laser pointers, a few servos and motors to make the lasers move as time passes, and of course, the IKEA BLANDA salad bowl ...

[GeraldF6] built an Arduino-based clock. That’s nothing new but thanks to a MOVI board (ok, shield), this clock has voice input and output as you can see in the video below.

Full instructions on how to create your very own Arduino music player and alarm clock have been kindly published by Dejan Nedelkovski with all the code you require.

Here is the circuit of an Arduino-based Panic Alarm! The wiring is very simple so that even a novice can construct this interesting circuit without any difficulty. Arduino is a family of ...

The alarm/target works using a piezoelectric sensor attached to the clock’s housing. When the alarm sounds, if it senses a dart hit by counting the signal pulses generated, it turns off.

Prototyping was done on an Arduino, and there's also iPod integration, an FM radio and an accompanying web interface which can also be used to program and manage everything.

[Brad] was asked by his Sister to design a motion-based alarm that would help her catch her son sneaking out of the house at night. Obviously this didn’t need to be a long-term installation s… ...
