Arduino Gsm Shield

Some days ago we launched our new product, the Arduino Gsm Shield, together with an intro video explaining how to make the first steps into the creation of interaction with it.
Today we’re publishing another video with a second step-by-step tutorial by David:

 

 

And we want to share some more because last year at the Malmo University K3 during the second year in Interaction Design BA, David Cuartielles and Tony Olsson run a course where students had to work on a project with state of the art of technology using wireless communication as a main mode of operation.

As one of the tools, 30 students could experiment with early prototypes of the GSM shield  and they came out with different projects and ideas.  Here you can see one of the proposals that made it to the finals at a M2M contest arranged in Sweden by Tele2. (more…)

Data-logging made simple with Arduino

Wednesday, January 23rd, 2013

One of the best capabilities provided by Arduino regards its very high modularity, which helps users to quickly translate ideas into physical artifact, as practically demonstrated by Mauro, which shows on his blog how to build a simple data-logger by properly combining different shields. By using few additional components (mainly resistors and buttons) a fully-functional data logger can be easily implemented.

A cheap WiFi interface for Arduino

Thursday, December 27th, 2012

In this tutorial, Luca shows how to add WiFi connectivity to your Arduino boards without using a WiFi shield. Instead, he has combined a standard Ethernet shield with a commercial (and quite cheap) WiFi router:

I found the TL-WR702N nano router by TP-LINK that, with a cost of about 20€ on eBay, can work also as a wireless client: in this mode the router acts like a “bridge” between the device connected to its ethernet port and a Wi-fi network.

After a simple setup, where Luca configured the router as a WiFi client, the Arduino board has become accessible from the wireless network. Enjoy! :)

Arduino-controlled blinds: a tutorial

Friday, October 5th, 2012

Have you ever wanted a smart home that can automatically adjusts the blinds for you? If so, this project is for you.

In this instructable, the author describes his approach to “smart blinds”, by using an Arduino board, an ethernet shield, a motor shield and a couple of sensors.

By means of a simple web-based GUI, the user can manually open and close the blinds, or he/she can setup both temperature and brightness thresholds in order to automate the whole process. Finally, opening and closing events can also be scheduled at pre-defined times of the day, if necessary.

The complete tutorial, together with the source code of the project, can be found here.

Arduino Wifi Shield is back on the store!

Tuesday, October 2nd, 2012

We’re happy to announce the Arduino Wifi Shield being back on the Arduino Store. Since we launched it back in August we had an overwhelming request for the product that ended up in solding it out.

Welcome back, bro.

Arduino based Milling Machine

Monday, June 25th, 2012

This is a working model of an Arduino based Milling Machine created using FischerTechnik. For those of you who are unaware of FischerTechnik, it is similar to the LEGOTM Building Blocks.

milling-machine

A group of four Mechanical Engineering students at the Delft University of Technology (Netherlands) created this project as part of their Mechatronics class in their Second year of Bachelor of Sciences (B.Sc.) Program.

Laurens Valk, one of the creators, explains the essence of Arduino in the project:

“The system uses the Adafruit motor shield to run two stepper motors, and the Sparkfun EasyDriver for the third stepper motor. The Arduino runs code that listens to Matlab commands over USB. We expanded that code a little to make it possible to add the third stepper motor and some other commands. Most of the actual code was programmed in Matlab, with the Arduino as the interface between computer and motors/sensors.”

We had a little chat with Laurens. Here is the excerpt:

 

When did you first hear about Arduino, and when did you first start using it?
I’ve seen a lot of Arduino projects over the years, but this was the first time we used it in a project. Personally, I usually build robots with MINDSTORMS NXT, but this felt like a good opportunity to combine mechanical work (the printer hardware) with real electronics (Arduino).
How did you end up making a Milling Machine/ 3D Printer for your project?

We chose to come up with our own design challenge and decided not to do the standard exercise. Initially we thought about making a (2D) plotter or scanner. Then quickly we started thinking about the same things, except in 3D. One of the projects that inspired us was the LEGO Milling Machine by Arthur Sacek. Both a scanner and printer would still be doable in 3D, but the time was limited, so we settled with the printer idea.

All construction had to be done in one workweek for logistical reasons. To make sure we were able to finish in time, we prepared much of the electronics and software outside the lab. We finished just in time, but unfortunately we could do only one complete print before we had to take it apart. Not surprisingly, it was very exciting to wait for the result of the one and only complete test run. We couldn’t see the result until we used the vacuum cleaner to remove the dust.

Here is a video showing the working of this machine. [And the Vacuum Cleaner Laurens is talking about]:

This gives an Insight into the many feats that an Arduino can accomplish.

 

Quick tutorial: current sensing for DC motors

Friday, June 15th, 2012

On her blog, Dustyn Roberts presents her own experience on current sensing for controlling DC electric motors with an Arduino board and an Arduino Motor Shield. This shield, based on a L298 H-bridge, provides two current sensing pins to the user, which can be used to measure the instantaneous current absorpion by each H-bridge. After some trials, Dustyn managed to have a quite clear picture of the absorption behavior of the DC motor:

Sample code and updates can be found on Dustyn’s blog.

Mexico reporting: Don Ingeniero and his Anti-shield

Friday, February 10th, 2012

I spent the day in Mexico City buying components for my forthcoming Euroaxacan workshop in electronics and software for craftsmen. I usually get here fairly cheap wheels for my robots, nice soundspeakers for building music instruments, wire -lots of wire-, great responsive buttons and some other stuff. I try to avoid LEDs, since they are more expensive than in Europe … those and the Arduino boards I bring from home. I usually get them at Electrokit, which is very close to my studio in Malmo.

 

 

(c) 2012 D. Cuartielles, Don Ingeniero showing off his Anti-Shield

The street where to find the electronics in Mexico is called Republica del Salvador. In about 100 meters you can find more or less everything you need: motors, potentiometers, wire, USB cables, breadboards, Atmega8L … but also, since two years ago there is Electronica Estudio, our only distributor in the city. I like passing by to visit to Don Ingeniero (Mr. Engineer) or how I like to call him. We usually speak for a while about the future of the platform, I get to see his designs and we plan for forthcoming events (beware, I will be making something during the Easter week at Electronica Estudio).

This time, Don Ingeniero flashed me with one of his biggest sales. He likes to call it the anti-escudo (Spanish for: anti-shield). It is a shield with 8 relays and 3 pin connectors for servo motors. He of course realized that a lot of people just want to hack their home appliances, so his local factory is making a lot of those anti-shields. The reason behind the name? That he decided to put the board upside down. Don thought I wouldn’t like it … the fact is that I loved it, yet another reason to show ToDo’s great design on the boards. You can see it is Arduino even from the back.

Next I will leave for Oaxaca to run a workshop at the Talleres Comunitarios de Zegache until February 22nd, 2012. If you are around the area and want to hang out, just drop me a line at d.cuartielles AT arduino DOT cc, or @dcuartielles on twitter.
