Arduino Shield ListArduino Shield ListArduino Shield List

Thursday, October 14th, 2010


[Arduino Shield List] published an updated list of ALL Arduino shields. From the Ethernet Shield (this links to the new one with Micro SD support, Mega compatible) to the more exotic ones.

Sick of trying to figure out which pins are used by some obscure Arduino shield? Can’t tell whether two shields will be compatible with each other?

This shield database arose out of a discussion on the Arduino Forums about the need for a comprehensive online reference for shield pin assignments. It lists as many Arduino shields as I can find along with their pin usage, making it easy for you to determine if particular shields are compatible.

Once again, a community effort makes our life easier. Bookmarked. Thanks Jonathan.

Open source Breathalyzer? There’s a shield for thatOpen source Breathalyzer? There’s a shield for thatOpen source Breathalyzer? There’s a shield for that

Friday, September 17th, 2010

I was really impressed from this instructable on a brethalizer microphone. [Caring Smith] and [GfxHax] worked on a more reliable project: a DrinkShield.

The GfxHax drink shield is an Arduino shield that converts an arduino into an Open Source Breathalyzer.  It come complete with a light bar to show the intoxiciation levels.  There is a series of 11 lights down one side of the shield that go from green to yellow and ultimately to red.  There are also player ready lights.  Why are there player ready lights?  Well, this is because the shield is not just a standard Breathalyzer but can be used as a party game.  With the GfxHax drinkShield you also get a GPL game that lets you play with your friends and keep highscores!  This software is licensed under the GPL so you can add features and will have unlimited free updates to new versions.

Mobile Home Automation Via Android

Thursday, September 16th, 2010

I created this project and my target is improve the comfort of my home. Taking a look around I noticed that home automation solution proposed by the big market player are too much expensive for me and, above all, I should create new wires connections between light, plug, etc.. and the control box.
My idea is use what we already have without spend lot of money to buy a owner solution, so I started with arduino, my android mobile phone, some relays and my home.
I have a nice home, 2 bad rooms, kitchen with living room and it was very nice tka e the control of the lights, gate and door with my mobile phone.

[Mattia] have realized home automation via internet, using:

[...] an Arduino 2009 with ethernet shield and the game is very easy, I send some http message to arduino, he moves some relays and give me back a JSON response. Not so hard, but the hard business is interfacing with the electrical wiring of home, with some patience I found what I need and I linked those wires at the relays.

A chi non è mai capitato di restare chiuso fuori casa senza le chiavi? Beh a noi spesso e ci sarebbe piaciuto aprire il nostro cancello o porta di ingresso usando il telefono cellulare che abbiamo sempre con noi, il bisogno aguzza l’ingegno…ed ecco fatto! Ci siamo guardati un attimo in giro ed abbiamo recuperato un po’ di informazioni su Arduino, la sua filosofia a “brick” ci è sembrata l’ideale per fare quello che avevamo in mente, il mio HTC Hero con Android OS ha fatto il resto.

[Mattia] ha realizzato un progetto di automazione domestica usando Arduino Duemilanove e Ethernet Shield:

[...]Bisogna far comunicare Arduino con il nostro telefono, la soluzione più pulita che mi è balzata in mente era quella di usare il protoccolo http per farsì che la comunicazione avvenga  e JSON per scambiarsi i dati agilemente.

Updated Ethernet Shield: micro-SD card slot, Mega support, and reset controller.

Wednesday, August 11th, 2010

New, updated Ethernet Shield version. Mega-compatible and with micro-SD card slot.

We’re very happy to announce an updated version of the Arduino Ethernet shield, with some nice new features. This revision incorporates a micro-SD card slot so you can store files to send over the network. It’s compatible with the Arduino Mega (using the SPI pins on the ICSP header). It adds a reset controller which should address the problems some people have had getting it to work directly on power-up. All-in-all, we think it’s a well-rounded upgrade to a useful product.

Arduino Shield PCB: step by step guide

Thursday, August 5th, 2010

[Sircastor] a.k.a. AaronEchie shared a nice link on the Arduino Forum,  a step by step guide to skecth (and possibly send to production) a PCB shield for your Aruino using CadSoft’s EAGLE program and SparkFun EAGLE library.

So you’re pretty fond of your Arduino. You make blinking lights, and beeping noises. You’ve made a robot that was pretty cool. Or maybe you didn’t. Who cares, You’re ready for the next step. You want to extend it. Although you can just plug in wires, there’s something very appealing about making a shield. Instead of a rats-nest of wires piled about and plugged into your prototyping breadboard, you can have a nice clean shield with labeled connections and a smaller footprint. So here I’m going to tell you everything you need to know to make a schematic and PCB layout, and get a beautiful shield that will plug into the top of your Arduino.

OpenMoco strikes again: the DollyShield

Friday, July 23rd, 2010

Some time ago I headed in one of the most complete DIY photo/cinema solutions for low-budget productions, the OpenMoco. It seems they spent some time in prototyping a brand new shield:

The DollyShield is an adaptation of the Arduino Motor Shield v3 that provides directional PWM control of two DC motors, at up to 1A of current each.  In addition to the motor drivers, it also provides a stereo plug with dual opto-coupled outputs for direct camera control, a 2×16 LCD, five user input buttons, and four auxilliary inputs or outputs through two stereo jacks.  It is designed to provide an inexpensive and easy-to-use interface for two-axis motion control integrated with a camera.

Introducing Centipede Shield

Wednesday, June 9th, 2010

[Macegr] arduino forum user:

Finally, we have these in production! Took a lot longer than expected, due to some other urgent projects with Tangible Interaction, and Maker Faire. Anyway they’re here and I think they look great.

The Centipede Shield adds 64 general purpose digital I/O to your Arduino. By “general purpose I/O” I mean that each pin can be individually configured as an input or an output, just like the normal digital pins on an Arduino. We’ve also cooked up a library that makes it easy to talk to the Centipede Shield; the syntax very similar to the normal Arduino digital pin commands.

An Arduino Watch you would actually want to wear

Wednesday, June 9th, 2010

Lovely watch:

Leather work, copper tubing, small easy to use package. Now that is a beautiful Arduino Watch. [Matthew Garten] has retrofitted his old Arduino Watch and given us the details that we crave.

Ultrasonic Arduino tape measure source code

Thursday, June 3rd, 2010

Nice free code. To be posted.

Here’s the source code for the Arduino + PING))) + 7-Segment Shield ultrasonic distance sensor project I build for this video. It is the progenitor of my Arduino Nerf sentry gun code, which I’ll be posting soon. Warning: my code gets the job done, but isn’t elegant.

Digital camera control using Arduino USB Host Shield

Tuesday, June 1st, 2010

nice (and deep) intro to Arduino driving Cameras via USB.

I’m starting new series of articles describing exciting field of digital camera control. In modern cameras, USB port can be used not only for transferring images to a PC, but also for sending control commands to the camera. It is often possible to send commands which “press” the shutter button, modify shutter and aperture values, some cameras are even capable of doing focus control. At the same time, new shooting techniques, such as HDR and stacked focus, require that a photographer makes several shots, slightly modifying one or several shooting parameters from shot to shot. Even age-old time lapse technique could use some automation. Since camera manufacturers are, as always slow to implement there cool features, Arduino comes to the rescue.
