DIY electronics is entering a golden age with the help of powerful, cheap, programmable devices like the Arduino micro controller and Raspberry Pi mini computer. But the DIY potential of these new ...

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

With your breadboard connected to the Arduino and the power supply plugged into an outlet, plug the Arduino back into the computer with the USB cable. Next, run the Processing code we compiled ...

The goal of this module is to teach students about the properties of sound and computing distance with an ultrasonic sensor. The program can also be used to measure the relative distance. This module ...

[IngGaro]’s latest project uses the full range of features available in this versatile microcontroller and has turned an Arduino Mega into a fully-functional home alarm system.

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.
