Create a Wireless Alarm Clock With Arduino
Alarm clocks are cheap and plentiful, but rather boring. If you want to create your own, Instructables user Paranoid Legend will show you how to create one with Arduino.
The alarm clock is made using an Arduino Mini and a TFT screen. You can turn the alarm on and off by flipping the watch, it charges via the micro USB port and even detects your presence and saves energy when you are not around. You can find a tutorial on how to create this for yourself on Instructables.
