Turn on PC, server, computer automatically using arduino without the need of pressing the power switch (such as in ATX power supply). Once the power source is connected, arduino will immediately press the switch.

Arduino based Coffee Machine Alarm

Keeps disks awake by maintaining a wake file on any number of disks.

This Arduino project is designed to utilize a DS3231 RTC module and Liquid Crystal I2C to display the time and temperature. A push button is required to manually turn on and off the LCD. There are two programmable alarms (nap time and night time) that are used to turn on the LCD for 30 minutes.
