I was looking for a way to handle wireless communications between two Arduino boards. Other options like Xbee or Bluetooth were going to cost $50 to over $100. Then I found a cheap RF transmitter and receiver at Sparkfun. The total cost is only $9!
The format of this book is very different from the regular O'Reilly books. It is written by a geek for geeks. So it doesn't start with a smooth introduction about the basics. DIY Projects, Inspiration, How-tos, Hacks, Mods & More @ Makezine.com - Tweak Technology to Your Will
Overview In this tutorial, you'll learn how to control a DC motor's direction using an H-bridge. To reverse a DC motor, you need to be able to reverse the direction of the current in the motor. The easiest way to do this is using an H-bridge circuit.
Arduino Tutorial: An Introductory Guide Update! Don’t miss our famous article:Ã‚ Top 40 Arduino Projects of the Web. Previously we introduced you to the Arduino and itÃ¢â‚¬â„¢s awe-inspiring incredibleness. Now weÃ¢â‚¬â„¢ll take you on an in depth plunge with enough resources and projects to keep you occupied for the next decade.Ã‚ The best place to get started would definitely be their comprehensive website.
In this tutorial I’ll describe how you can connect the optical sensor inside a cheap mouse to your Arduino and have it read out the x- and y-movements. This will enable your Arduino to handle mouse input, detect surface movements, measure surface speed, etc. Materials This is what you need: Martijn Thé – iPhone & iPad Development & Interaction Design » Interfacing an optical mouse sensor to your Arduino

In this tutorial, you'll learn how to control a high-current DC load such as a DC motor or an incandescent light from a microcontroller. (:toc Table of Contents:) Parts You will need the following parts for this tutorial. Tutorials / Using a transistor to control high current loads with an Arduino
Warning!!! This project deals with AC electricity which is dangerous if you don’t know how to treat it safely. You must treat electricity with caution. There are many books and websites about electrical safety procedures and if you’re not sure how to be safe you should read that information.
Often when working on microcontroller projects you need a background function to run at regular intervals. This is often done by setting up a hardware timer to generate an interrupt. The interrupt triggers an Interrupt Service Routine (ISR) to handle the periodic interrupt. Arduino Interrupts | uC Hobby
Arduino Tutorial Learn Electronics using Arduino! ladyada.net So, I get two or three emails a day, all basically asking the same thing: "Where can I learn about electronics?"
Note for Arduino 1.0 An updated version with 1.0 support is available on github. Installation instructions are at the bottom of that page. Let me know if you encounter any problems. Do you want to control your Arduino with an IR remote?
... an evolving index of practical subjects for the Arduino and Freeduino microcontrollers, as found in the Arduino site, Playground wiki, forum and that big WWW thing. Everything you read here will work on Arduino, the many versions of Freeduino, the Barebones and RBBB, the Boarduino, the iDuino and MAXserial, the eauDuino, the Jeenode, the many Arduino-compatible boards listed below, and of course the new-kids-on-the-block, the Sanguino, the Freeduino EPIC and the Arduino MEGA. Because of the different hardware layouts of these boards, slight modifications will occasionally be required between physical platforms. Last update: July 7th, 2010. Serving over 19,000 unique Arduino/Freeduino junkies a month without charge or adverse side effects since August 2007! To suggest a link, email us!
Spooky Projects is a set of four 3-hour classes in October 2006 hosted by Machine Project and taught by Tod E. Kurt. It is an introduction to microcontroller programming and interfacing with the real world using the Arduino physical computing platform. In the class, participants are shown and experiment with the Arduino’s capabilities and learn the basics of common microcontroller interfacing, such as: digital output to control lights and LEDs, digital input to read switches and buttons, analog output to control motor position or LED brightness, and analog input to read sensor inputs. From these tools all sorts of interesting projects can be created. In the class, a few simple project sketches are covered using the provided parts kit, under the theme of spooky animatronics for Halloween.

Meditation strikes a special chord with me as a maker because it is said to foster creativity, intuition, imagination, and fantasy. I can't think of traits better suited to making. I've tried meditation in the past, but it didn't seem to stick. When I saw that NeuroSky's Mindwave headsets had dropped to $100, I couldn't resist trying meditation again, this time with feedback. These headsets measure electrical signals from your brain and determine two main metrics: attention and meditation. Make: Online | Arduino
This is the start page for our series of over fifty Arduino tutorials. Each tutorial from chapter zero to thirteen will cover a variety of topics and lessons, then from chapter fourteen each chapter will cover a particular topic. If you are looking to learn about the world of Arduino – this is a great place for beginners to start, or for more experienced users to brush up on their knowledge.
