Real-time room temperature on your Website using Arduino

This is how to push high resolution real-time data from Arduino-based temperature sensor to your web page without any server-side coding. Arduino is a great device for collecting, storing and transferring data from various sensors but there are times you need to make your data accessible from any place over the internet, like I did for room temperature in my study. That’s when this solution may come handy. ...

Web Client Repeating using Arduino

This example shows you how to make repeated HTTP requests using an Ethernet shield. This example uses DNS, by assigning the Ethernet client with a MAC address, IP address, and DNS address. It connects to http://www.arduino.cc/latest.txt. The conent of the page is viewable through your Arduino's serial window. Circuit The Ethernet shield allows you to connect a WizNet Ethernet controller to the Arduino via t ...

Internet connection indicator box with restart button

THE SETUP For an interface I thought 3 LEDs would be simple enough: Blue for everything is fine (as blue LEDs are cooler than green ones); red for something is wrong; and yellow for the modem and router are being restarted. I added a button to do the actual restarting as I wanted it to only be done deliberately. For the internals I went with: Arduino mini pro clone 5v ENC28J60 Ethernet connector (datasheet) ...

Arduino-enabled Patron Interaction Counting using arduino

Using the Arduino development board (http://arduino.cc) has become a very popular way to create hardware prototypes that bridge the divide between the physical world and the Internet. This article outlines how to use an Arduino, some off-the-shelf electronic parts, the Processing programming language, and Google Documents to create a push-button reference desk transaction tally device. The design: plugged i ...

Twitter Poem Box

This is a project that was inspired by Marc de Vinck's Kitty Twitty Cat Toy http://makezine.com/22/kittytwitty/ . It incorporates an RFID reader and the BlinkM, a programable RGB LED. The lamp tweets random colored poems when it detects one of the three RFID cards which each represent one of the primary colors of light. These colors can be mixed allowing you to make seven different colors of poems. An examp ...

Displaying Twitter feed without a PC! using Arduino

There are a lot of Twitter feed readers around the Web that use Arduino AND a PC to display twits on LCD displays or whatsoever. Then, I decide it was the time to design a solution for performing the same job WITHOUT A PC, and here's the project. In a simple equation: Arduino + Ethernet Shield + LCD Display + Twitter = automatic Twitter feed reader with LCD! The items you need are the following: - Arduino ( ...

Google Docs and the Arduino Yún

Introduction This is the second in a series of tutorials examining various uses of the Arduino Yún. In this article we’ll examine how your Arduino Yún can send data that it captures from the analogue and digital inputs and a real-time clock IC to an online Google Docs spreadsheet. Doing so gives you a neat and inexpensive method of capturing data in real-time and having the ability to analyse the data from ...

Nocturnal Emissions: My Arduino Powered Internet Enabled Dream Generator

We all need to dream more so I've created this Arduino Powered "dream generator" to help plant the seeds for some big thinking craziness.  When you approach the generator a Maxbotix ultrasonic sensor triggers lights and music that draw you in so you can stare into the blue LED enshrouded infiniteness of the box.  Press the pulsing blue button and a thermal receipt printer generates your dream which is mashe ...

Google Weather on graphical display with Arduino

In this project, I am using an Arduino board to show forecast of the weather from Google Weather service on a VGA screen. The display is obviously graphical one, with icons and some colorful text. It is one of those gadgets I wanted to have for some time now – A weather forecasting display that is there just like the wall clock. Yes I know you got nicer looking things on your angry-birds machine... I simply ...

Bluetooth plus Infrared Controlled Robotic Arm

Hi. I’m Darren a 17 year old hobbyist, and this is the first Instructable I’m posting here, so I apologize if it kinda sucks! I hope it's good enough... So how did the idea of a robotic arm come to me? Well, the first thing I remember is our chemistry teacher (!) coming to me yelling that she has a project for me. It was for science Olympiad, however, apparently it was different from all the others, "someth ...
