In this project, we will go over how to connect a microphone to an arduino so that the arduino can detect whether there is sound in the environment or not. This circuit is only capable of detecting whether there is sound in the environment or not. It won’t be able to record the words that

3/16/2011 EDIT: The Wing Kp Predicted Geomagnetic Activity Index model is now deployed and operational. Costello is now considered non-operational and will be discontinued on 23 Mar 2011. Comments and questions are welcomed at [email protected] The Wing Kp Predicted Geomagnetic Activity Index model is known to perform well for large geomagnetic storms and includes both

The platter of a hard drive spins well over sixty times a second. If a narrow slot was cut into the platter to allow LEDs to shine through, we can achieve flicker fusion and trick the eye into seeing a stable image. This phenomenon is known as persistence of vision (POV). There are many examples

In this project, we will show how to drive a single 7 segment LED display with an arduino microcontroller. A 7 Segment LED Display is an electronic device housing 8 individual LEDs. Using this device, we can display all numerals and many alphabetical characters and many more types of symbols. The 7 segment LED is really a

Water is a precious resource. Millions of people do not have access to clean drinking water, and as many as 4000 children die from water contaminated illnesses every day. Yet, we continue to be wasteful with our resources. The overarching goal of this project is to motivate more sustainable water use behavior and raise awareness

I created this Instructable for the absolute n00by robot wannabe. I have noticed a huge jump in the number of beginners getting into the hobby and the number of “how do I” questions seem to be mounting. Maybe this humble little Instructable will help one or two create their first robot. You will find basic

Every single location in the entire globe can be specified in terms of geographical coordinates. The geographical coordinate is a system which specifies any given location on the earth surface as latitude and longitude. There are devices which can read the geographical coordinates of a place with the help of the signals received from a

Have you ever felt like the mail sound on your Mac just wasn’t enough? Simple sounds and alerts just don’t cut it for you? You want something more apparent and rewarding? If so, this is the Instructable you’ve been looking for. In this Instructable, I’ll show you how to hook up your Arduino to your
Create an Applescript/Arduino Alert flag. using arduino Continue Reading
The Time Sensing Bracelet is a fabric potentiometer. You select your desired time of day by making contact in the corresponding position on your wrist – where your watch would normally be. There is no point to it but fun. Update: Using some wire wrapped around the central popper to make contact with the resistive

The Raspberry Pi is much more powerful than an Arduino but it has a few limitations of its own. Its I/O is much more limited, it can’t use common Arduino shields, and it needs a regulated 5V power supply via its USB connection. All those limitations are solved with the PiLeven. The Freetronics PiLeven is
