Great Arduino Tutorial Download

The folks at Earthshine Electronics have produced a great Arduino tutorial. It's full of schematics, program code, and build instructions with clear diagrams. I recommend you download it at http://www.earthshineelectronics.com/files/ASKManualRev4.pdf

The Arduino Breathalyzer

Why you would want to build your own breathalyzer? Well, everyone has their own reasons I guess. For us, it's enough to know it can be done. It's not precise, but will give you comparison values ("I'm drunker than you are". "No, I'm drunker"). I don't recommend this as a reason for drinking games, but it is an interesting application of technology.

Internet NTP Time Clock

Want to know what the official time is? Setup this Arduino clock, plug it into your dsl/cable router, and always have the exact time. It uses the Internet NTP protocol to get the current date and time, and display it on a LCD. Sounds pretty simple, right?

The LCD for our HVAC Thermostat

The LCD for our HVAC Thermostat is on it's way. It's a very cool looking 16x2 with black letters on orange background. At less than $10 delivered, it's a great deal.

Connect Your Arduino to the World

With an Ethernet Shield, the Arduino can talk to other computers around it, and those around the world.

The Arduino and the LCD Display

Your Arduino has things to tell you. One of the easiest ways to let it communicate is to attach a character LCD. These LCD modules are a lot of fun, however they can be tricky to get working right. Many a hacker has spent hours trying to get one working, only to suffer through frustration and humiliation. Hacktronics is here to help. Our LCD HackPack, along with this tutorial, has everything you need to get an LCD working quickly with your Arduino. An LCD module connected to your Arduino can be a great debugging tool for your program. The LCD modules covered here are based on the very popular HD44780 controller.

Arduino Motion Detector Using Parallax Passive Infrared Motion Sensor

Looking to detect motion with your Arduino? Great for security or robotics apps. There are some neat projects including temperature sensing, exhaust gas analyzers, and more at http://www.pdqweb.net/arduino-motion-detector/

Arduino based contact-less tachometer

If you need a way to detect the speed of a rotating device, a tachometer is the way to do it. If you can't add slots and a hall sensor, a simple contactless IR sensor and reflective tape may be just the ticket. See http://www.embedds.com/building-a-contactless-tachometer/ for more info.

The Robot Pet

Back around 1980 or so, I bought a book on how to make a robot pet. It would let you know when it was hungry (low batteries), follow you around, and avoid obstacles (ultrasonics). Well, microcontrollers have come a long way, and the ability to imitate life has improved greatly. Check out this example of a modern robotic "dog":

Solar powered Arduino (and cellphone) Redux

I received a FreeLoader Pico the other day, and I put it to work charging my cellphone while on the go. It does a fantastic job of that, but I wondered what else I could use it for. Ah, a power source for my Arduino Microcontroller. It does a great job of that as well. No more looking for power connections, I just set the small solar panel with integrated Li-ION battery in the sun and charge. A bargain at $30.

DFRobotShop Rover Now Available at RobotShop.com

RobotShop Distribution Inc. Partners With DFRobot To Release the “DFRobotShop Rover”, a Versatile, Tracked, Arduino-Compatible Platform

RobotShop Distribution Inc. announces the new DFRobotShop Rover is in stock and ready to ship. The DFRobotShop Rover was a joint project between DFRobot and RobotShop to create a low cost Arduino-based and shield compatible tracked platform.

The Arduino microcontroller has been around for many years and is exponentially increasing in popularity because of its straightforward design, features, price and ease of use. RobotShop had been selling the Arduino microcontroller for many years, but had not seen a commercial mobile robot that incorporated it into its design. In 2008, RobotShop released the “RobotShop Rover”, also a tracked platform kit, which included a standard Arduino Duemilanove microcontroller. The DFRobotShop Rover continues this trend by including all the features of a standard Arduino Duemilanove with the parts essential to creating a tracked robot into a minimalist design.

The $10 Minimalist Arduino

The Arduino is already inexpensive ($20-$40), but the basics can be implemented for less than $10 if necessary:

Here is a recipe for using the atmega168 as a standalone Arduino. It uses the internal oscillator of the Arduino running at 8mhz, and is powered at 3.3 volts.
