On saturday 15th of November we are going to be in London  for the Elefant&Castle Mini Maker Faire at the London College of Communication. We’ll have a booth with some projects made with Arduino boards and  demos to test our new Arduino Zero. You can visit our booth located in The Street area of the First Floor (check the Map).

Massimo Banzi will be around as well in the afternoon and you can come and say hi to him at the booth starting from 3pm.

The goal of this project was to create a small device, which detects movement in protected areas (e.g. tables) and allows you to speak usual phrases in your voice to the cat to control its behaviour when you are away. It’s called Cat Protector and prototyped on Arduino Uno  by Lucky Resistor, a creative guy who enjoys software development and electrical engineering:

I started with a prototype, using an Arduino Uno and a large breadboard. The first step was to realize an acceptable sound output. To realize this I added a shield with SD card adapter and wrote some optimized code to stream sound from the SD card in 22.1kHz using a 12bit DAC. The amplification to a speaker completed this part of the project where I have two solutions. Next I experimented with different motion sensors to detect the motion of the cat and finished the hardware part using a dual color LED for a simple status display.

Creating a compact device from the prototype was the next challenge, I could place the whole circuit I used on a small prototyping area and squeezed everything in a small casing. From outside, the device looks simple and tidy.

He documented everything in details on his website, especially the software part:

I read so many Arduino related articles and tutorials, but most of them stop when the prototype is running. I hope this documentation helps people to see how to structure Arduino software to make it extensible and keep it readable. This is especially necessary to write more complex logic than just to blink some LEDs. Also I hope to give some inspiration how to develop the prototype to a final device.

Servos are composed of an electric motor mechanically linked to a potentiometer and they are able to translate the width of the pulse into a position. When you command the servo  to rotate, the motor is powered until the potentiometer reaches the value corresponding to the commanded position.

Today we’d like to share with you a tutorial with the aim of showing how to make a simple light follower made of cardboard using Arduino Uno and a microservo, in this case the Analog 180° Micro Servo.

Follow the step by step lesson to build one yourself.

We are really happy to share with you that at the beginning of the week Paola Antonelli (Senior Curator Department of Architecture and Design) and Michelle Millar Fisher, (Curatorial Assistant, Department of Architecture and Design) published on the Moma blog a post announcing the acquisition of Arduino  and other DIY electronic devices in the collection of the  Museum of Modern Art of New York City, with this explanation:

As design curators, we have an instinctive response to designs we find compelling, and when that feeling survives the passing of time, we know we’re on to something worthwhile. We believe our new acquisitions will withstand that test. All promise to make a difference—not just in the utopian “design can save the world” kind of way (always good, but often a high bar for any one object), but at the very micro level. We all know what it feels like to master a skill previously thought completely outside our abilities, or to unlock new possibilities of experience and thought. It’s exhilarating, life-changing, and (healthily) addictive, the same reason people keep coming back to see MoMA’s Pollocks and Picassos—and, we hope, this new group of humble masterpieces.

That’s how they are describing Arduino:

A tiny but powerful microcontroller, the Arduino is an open-source, programmable microchip housed on a circuit board that fits in the palm of one’s hand—an apt metaphor for the control over design functions that it allows its user—and a pillar of contemporary maker culture and practice. Designed by a star-studded team, the Arduino can be programmed to drive components such as sensors, LEDs, and motors in order to build and develop all kinds of interactive objects. This new building block of design has resulted in applications as diverse as light sculptures, digital pollution detectors, and tools to help people who are unable to use such common interfaces as a computer mouse. Beyond its concrete applications, the Arduino acts as a platform for the interdisciplinary practice that lies at the heart of so much compelling contemporary work across science and the humanities.

We’ve been amazed by the great projects coming up the week before Halloween on Twitter and Gplus community and still being submitted to our blog.

Leah Libresco published an Instructables about a pair of interactive gauntlets made with Arduino Lilypad:

This Halloween, I decided to be Alina Starkov from the Grisha Trilogy by Leigh Bardugo. In the books, she’s the one and only Sun Summoner, doing magic with light and heat.

Since those powers were beyond me, I put together a set of Arduino-controlled gauntlets instead, that would light up on gesture commands and slip under my sleeves. [This set up, with a few tweaks, would probably serve you well for Iron Man, too]

Instead of using a single position value from the accelerometer to turn the LEDs on and off, I picked two different triggers, so that it would be easy to *choose* whether I wanted my hands illuminated when they were straight out in front of me (a necessity, since I plan to host a party in these!)

Full construction and code are available at this link, below you can see the project in action!

Arduino boards are able to control small motors very easily and it’s just as easy when you have to deal with controlling large motors. In the following video tutorial by NYC CNC you’ll see two examples. In the first you’ll learn how to get up and running, to start, stop, control direction and speed of a large motor with Arduino Uno. In the second example, how to use two proximity sensors as limit switches and two potentiometers to allow on-the-fly speed adjustment.

Eva Taylor works at EKT Workshop and built an animatronic rod puppet Alien as a masterwork research project for the National Institute of Dramatic Art (NIDA) in Sydney Australia. It was inspired by the “bambi burster” built for the film Alien 3, although her creature is somewhat different.

The animatronics are controlled via a Playstation 3 controller, using a servoshock module between the controller and an Arduino Uno board:

It contains and 8 way 2 stage tail mechanism and animatronic lips, jaw and tongue. The remaining parts are rod controlled. A myriad of techniques were deployed in its construction – the torso and limbs were hand-carved from Queensland Maple while the joints were custom made from recycled parts of RC cars and planes. The skeleton of the tail was custom made from acrylic and cut on a laser cutter. The head contains an underskull of fibreglass, dental acrylic teeth and silicone skin. The muscle groups are also made of deadened, encapsulated silicone.

She shared with us the video above showing the main phases of the making-of process, while the one below gives you an idea of how  the puppet looks like in a more dramatic piece:

After the Bike Tachometer we posted back in September, Nikus  shared with us a new Instructable to show you how to build remote-controlled tank using a first person view (FPV) camera and Arduino Leonardo:

At the beginning I build only RC tank without FPV camera but when I was driving it in the house I have not seen where it is. So I came up with that I will add to it the camera mounted on a 2 servos. The range is about 100m, you can also ride with it at home. With this tank you can see what your cat is doing when you’re not looking. You can see it on a video

Watch it in action and follow the tutorial:

A week ago we were in London for an introductory workshop on the Arduino Yún. The participants were mainly beginners, knew the basics about Arduino and had the chance to learn about the Bridge library, how to control the board locally through the browser and to use Temboo to connect the plant to Twitter. See the pictures on the our Flickr account.

Arduino history is tied to the city of London: the first Arduino workshops ever took place right there.

We are now planning to organise more #ArduinoTour activities in UK and we are looking for teachers and ambassadors of the Arduino community in London and also UK in general. Are you interested? Fill the form!

Next workshop in the City is scheduled on the 20th and 21st of December and it’s focused on beginners. On the 19th from 6 to 8 pm there will be a public presentation on the Arduino project and also get in touch with possible collaborators. Take a look at the program and book your participation to the workshop – (location still to be defined, more news soon).

Jason from Make Magazine published a video tutorial on how to create an amazing choreography hacking your Halloween props using Arduino Uno:
