Drive a webpage in real-time using Arduino, SensorMonkey and Processing.js Remote visualization of real-time sensor data. This tutorial describes in detail how to use the free SensorMonkey service to push real-time sensor data from an Arduino to a webpage for visualization using Processing.js. No server-side coding or Ethernet shield is required. A standard, run of the mill Arduino will work perfectly. You'll also need a sensor to sample some values.
Beginners Guide Beginners Guide to Electronics by Martin T. Pickering Bubble Machine Making your own bubble machine is a really easy and fun project. It can be made from almost anything, glued and screwed together with an end result which will keep kids (and adults!) amused for hours. Maker Education Initiative Arduino Tutorial - Lesson 5 We've done a lot so far, blinking lights, printing messages...all of that stuff is output: signals coming from the Arduino. The next step is to start playing with input, with the Arduino responding to outside events. In this lesson we will begin with the most basic kind of input, a push-button switch!
PIR Motion Sensor PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. Blog Archive » The greatest electronics book ever written? Getting Started in Electronics , by Forrest M. Mims, III. is a spectacular introduction to the world of electronics. Ovidiu Predescu's Weblog: Arduino Tiny Web Server - part 3 Update (September 3rd, 2011): The code is on Github: A zip file of the latest version of Arduino TinyWebServer can be found here What is it? Arduino TinyWebServer is a library implementation of a small web server running on an Arduino Duemilanove or Uno using the new Ethernet Shield released at the end of September 2010.
Getting Data From The Web – Arduino + Ethernet Yesterday we covered how you would go about controlling pins of your arduino over the internet using the Arduino Ethernet Shield set up as a server. Today we are going to take a look at using the shield as a client to get information off of a web page, and report back. I used this method a few months ago when I made the Nixie Twitter follower counter dubbed Twixie. The ethernet shield can be used to access any non-password protected site with ease, but getting the information back to you is the hard part. For Twixie I created a special php page that queried the twitter API and displayed only the twitter count. This made it so I didn’t have to tell the arduino what to look for, or scour endless lines of HTML looking for a single number.
Arduino Tutorials - Ethernet+SD Whatsit? We just got the latest version of the Arduino Ethernet shield with a MicroSD card slot and I promised Bill Greiman I'd try out the latest version of his SdFatLib library so I decided to code up a simple Webified file browser. Its a quicky project and demonstrates what you can do, but it isn't 100% perfect so you should be ready to modify it if you'd like to do other stuff, 'K? Arduino 1-Wire Address Finder This tutorial has been updated to use version 1.0+ of the Arduino software, and compatible libraries. Please download the latest version of the Arduino software here: 1-Wire devices, such as the DS18B20 digital temperature sensor, are great to use with Arduino boards because you can connect many of them to a single IO pin. The freely available software libraries and example code make using 1-wire devices simple. There is only one problem we have seen with the examples on the web. If you have more than one device connected to a single pin, say an indoor temperature sensor, as well as an outdoor temperature sensor, how does your Arduino know which is which?
BB313: A Breadboarding Platform for the ATTiny2313/4313 February 28, 2012 AT 12:51 pm A little over a year ago, I started playing around with the newly available AVR ATTiny4313. It’s a neat little chip, and you can have a lot of fun with it. However, I soon got tired of wiring up programming headers, power supplies and all the other stuff you need to get up and running. I also grew wary of all this support circuitry taking up significant breadboard real estate. Open Source SRAM Memory Board I have designed a very simple PCB module that allows access to 512KBytes of Static RAM. It is compatible with any microcontroller with at least 13 free digital IO pins and the ability to run from a 3.3v or 5v supply. The module is breadboard compatible via a 15-pin 0.1" male header connector. The design is open source (licenced under Creative Commons) and the design files (schematic, gerbers, bill of materials and drillfiles etc) will be made available on this page soon.
Bread Head « Blondihacks A breadboard programming header for AVR microcontrollers I’ve been working with AVRs quite a bit lately, and I wanted a quick way to program them on a breadboard. Something that would be durable, and easy to stick into an existing circuit for rapid iteration of code. This is what I came up with. I call it the Bread Head. This is designed for 8-pin AVR microcontrollers.
