The LEDmePlay is an open-source DIY gaming console powered by an Arduino Mega. Games are displayed on a 32 x 32 RGB LED matrix housed inside an IKEA picture frame, and played using any C64-compatible joystick from the ‘80s. LEDmePlay supports several games, each of which are downloadable for free online, and Makers are encouraged to develop their own as well.

Its creator Mithotronic has also built a handheld variant for on-the-go fun, LEDmePlayBoy. This device is based on the same Arduino Mega, powered by eight AA batteries, and uses an analog thumb joystick and two fire buttons for control.

Interested? You can check out the LEDmePlay’s construction manual, and find all of the games’ source codes here.

With hopes of reinventing the way food is grown, Rory Aronson has developed humanity’s first open-source CNC farming machine. The FarmBot Genesis — which will begin taking pre-orders in July — is capable of planting seeds and then watering them precisely.

Designed with the Maker community in mind, FarmBot is driven by an Arduino Mega 2560, a RAMPS 1.4 shield, NEMA 17 stepper motors, and a Raspberry Pi 3. What’s more, all of its plastic components can easily be 3D printed, while its flat connecting plates can be made with either a waterjet, plasma or laser cutter, a CNC mill, or even a hacksaw and drill press.

The three-axis machine employs linear guides in the X, Y, and Z directions, which allows for tooling such as seed injectors, watering nozzles, sensors, and weed removal equipment to be accurately positioned. Impressively, FarmBot can cultivate a variety of crops in the same area simulatenously. 

FarmBot is controlled via mobile device or laptop, while its web-based interface makes customizing your garden as simple as playing FarmVille. You can also build and schedule sequences by dragging and dropping basic operations, adjust the parameters to your liking, and save. Meanwhile, a decision support system adjusts water, fertilizer and pesticide regimens, seed spacing, timing, and other factors based on soil and weather conditions, sensor readings, location, and time of year. And of course, FarmBot can be manually operated in real-time as well.

Aronson’s vision is to make precision agriculture open and accessible to everyone. Each FarmBot Genesis can be modified and augmented to suit anyone’s unique growing style and needs. For instance, you can power your machine with renewable energy from a small off-the-grid solar panel, or install a barrel to store and use rainwater.

Swedish electric car startup Uniti has unveiled an open-source, Uno-compatible board designed for controlling three-phase motors. The “Uniti ARC” combines the familiar layout of Arduino with a number of other powerful features that will help facilitate the prototyping of electronic machinery — which includes the company’s own EV.

Aside from transportation vehicles like cars, e-bikes and e-scooters, the Uniti ARC can be used with other equipment employing three-phase motors, such as CNC mills, conveyor belts, or even 3D printers.

In terms of hardware, the Uniti ARC is powered by an ATmega64M1 at 16 MHz, and comes with a 12-bit high speed three-phase motor controller, CAN 2.0 A/B transceiver for real-time communication, 10-bit digital to analog converter, and four analog comparators. In addition, it can be easily programmed using the Arduino IDE.

The ARC inherits the versatility of the Arduino and even expands it. Therefore, the possibilities of what you can build with it are only limited by your creativity. Every electric motor can also be used as a generator! Let your imagination go wild…

It is designed to empower makers, startups, educators and anyone else, to be part of the electric vehicle revolution by making electric car prototyping more accessible for a wider public.

The Boogie Cup is an interactive project controlling the music volume according to the number of cups used in a party and allowing party-goers to follow each other on Spotify. How does it work?

The Boogie Cup Holder uses an infrared distance sensor to detect how many cups are in the stack. As guests take cups, the sensor detects a change in distance, and increases the volume at the party. The Genuino MKR1000 wifi chip connects the Boogie Cup to the Spotify API. When two guests pass by with similar playlists, their cups light up. When they cheers, a message is sent to a server that enables each user to follow each other on Spotify.

The device was created by a team of student (Sophie Chow, Priscila Ferreira, Lars Kaltenbach, Mary Mikhail) during a 4-day exploration into Physical Computing  during the Interaction Design Programme at CIID with the support of Massimo Banzi and Dario Buzzini, with the aim to encourage new behaviors with ordinary objects.

Evil geniuses usually have the help of some anonymous henchmen or other accomplices, but for the rest of us these resources are usually out of reach. [Evan], on the other hand, is on his way to a helpful army of minions that will do his bidding: he recently built a USB-powered minion that turns a regular PS/2 mouse and keyboard into a Bluetooth mouse and keyboard.

[Evan] found his minion at a McDonald’s and took out essentially everything inside of it, using the minion as a case for all of the interesting bits. First he scavenged a PS/2 port from an old motherboard. An Arduino Nano is wired to an HC-05 Bluetooth chip to translate the signals from the PS/2 peripherals into Bluetooth. The HC-05 chip is a cheaper alternative to most other Bluetooth chips at around $3 vs. $40 for more traditional ones. The programming here is worth mentioning: [Evan] wrote a non-interrupt based and non-blocking PS/2 library for the Arduino that he open sourced which is the real jewel of this project.

Once all the wiring and programming is done [Evan] can turn essentially any old keyboard and mouse into something that’ll work on any modern device. He also put an NFC tag into the minion’s head so that all he has to do to connect the keyboard and mouse is to swipe his tablet or phone past the minion.

If you’re looking for an interesting case for your next project, this McDonald’s Minion toy seems to be pretty popular. PS/2 keyboards are apparently still everywhere, too, despite their obsolescence due to USB. But there are lots of other ways to get more use out of those, too.

Create

We are finally ready to release create.arduino.cc, the Arduino platform that will provide the community with a more modern and flexible tool to write code, a more integrated way of accessing content and learning while doing.

While we are still busy refining the web-based Editor (IDE) based on the feedback of the current beta-testing program, we are really excited to launch Arduino Project Hub, our tutorial platform powered by hackster.ioWe cannot wait to see all the projects made with Arduino and Genuino boards that you will submit! Comment on the tutorials you are curious about, and ‘Respect’ the ones you like the most. We will feature the best projects on the Arduino Blog!

AD_ProjectHub1

AD_ProjectHub3

Within create.arduino.cc you will be also able to access a new website focused on Internet of Things. Arduino IoT collects inspiring tutorials, and provides guidance for anyone who wants to get started tinkering with the Internet of Things. Most importantly it presents the “Arduino IoT Manifesto”, an important statement that will guide the development of our IoT products and tools in the coming years, and that we hope will be adopted by a larger network of people and industries. We propose these three principles for the future of this burgeoning industry: Open, Sustainable and Fair!

The post Hold This Smart Business Card to See Your Heart Beat appeared first on Make: DIY Projects and Ideas for Makers.

Hernando Barragán is the grandfather of Arduino of whom you’ve never heard. And after years now of being basically silent on the issue of attribution, he’s decided to get some of his grudges off his chest and clear the air around Wiring and Arduino. It’s a long read, and at times a little bitter, but if you’ve been following the development of the Arduino vs Arduino debacle, it’s an important piece in the puzzle.

Wiring, in case you don’t know, is where digitalWrite() and company come from. Maybe even more importantly, Wiring basically incubated the idea of building a microcontroller-based hardware controller platform that was simple enough to program that it could be used by artists. Indeed, it was intended to be the physical counterpart to Processing, a visual programming language for art. We’ve always wondered about the relationship between Wiring and Arduino, and it’s good to hear the Wiring side of the story. (We actually interviewed Barragán earlier this year, and he asked that we hold off until he published his side of things on the web.)

The short version is that Arduino was basically a fork of the Wiring software, re-branded and running on a physical platform that borrowed a lot from the Wiring boards. Whether or not this is legal or even moral is not an issue — Wiring was developed fully open-source, both software and hardware, so it was Massimo Banzi’s to copy as much as anyone else’s. But given that Arduino started off as essentially a re-branded Wiring (with code ported to a trivially different microcontroller), you’d be forgiven for thinking that somewhat more acknowledgement than “derives from Wiring” was appropriate.

See what we mean?

The story of Arduino, from Barragán’s perspective, is actually a classic tragedy: student comes up with a really big idea, and one of his professors takes credit for it and runs with it.

This story begins in 2003 as Barragán was a Masters student at the Interaction Design Institute Ivrea (IDII) in Italy. He was advised and heavily influenced by Casey Reas, one of the two authors of Processing.

Programma2003At the same time, Massimo Banzi is teaching a class in essentially microcontrollers-for-designers at Ivrea using a PIC-based board called the Programma2003 and a curious language that you’ve never heard of, “JAL: Just Another Language“. At the time, there was no GCC support for the PIC, so the choices for open-source development were few. Worse, most of the design students are using Macs, and JAL only compiles on Windows. It wasn’t user friendly.

Barragán’s thesis is a must-read if you want to know where Arduino comes from. The summary is everything you know now: it’d be revolutionary if one could make a hardware / software platform that were easy enough that artists and non-microcontroller-nerds could get into. This is exactly the revolution that was underway in the computer graphics front, powered by Processing. Make it open source and freely available, and you’ll take over the world. So he turned to the Atmel AVR chips, which had the GCC open-source toolchain behind it.

From Wiring to Arduino

WiringBoard-AssembledSo by 2004, Barragán had a few prototypes of Wiring boards out, and he and his fellow students were using them informally for projects. The GUI will look ridiculously familiar if you’ve used Processing or Arduino. Since the students were already familiar with Processing, it made a lot of sense to just clone it — with Casey Reas’ blessing of course. Barragán wrote a little program that maybe you’ve heard of: Blink.

Now Barragán needed a faculty advisor at Ivrea, and his interests clearly aligned best with Massimo Banzi. So with his thesis work well underway and Reas’ backing, Barragán took on Banzi as his advisor. With Banzi and three other faculty members, the Wiring platform got its first real test-run, the “Strangely Familiar” workshop and show (PDF). It was a stunning success — in the space of only four weeks students actually made stuff.

Barragán graduated in 2004 and moved back to Colombia. The success of “Strangely Familiar” lead Massimo Banzi to drop Programma2003 like a hot potato and teach his physical design classes using Wiring.

ArduinoPrototype1Work began on the Arduino project, according to Banzi, because he wanted a board that was cheaper to make than the Wiring board. So he replaced the ATmega128 microcontroller for a cheaper, smaller version, and chopped off everything that wasn’t “essential” from the Wiring board, like the power LED. This became the “Wiring Lite” board — and eventually the first Arduino prototype.

Giving Arduino its Due

It is not the case that Arduino doesn’t acknowledge Wiring at all. They do. There are a few sentences in the first paragraph of the Credits section of the website, as mentioned above. That and $4.50 will buy you a Grande, Quad, Nonfat, One-Pump, No-Whip, Mocha, but how much more can one ask for?

The Arduino project has been marketed with extreme savvy, something that cannot be said of Wiring. Banzi hooked up with influential people in the US, eventually friend-of-a-friending himself into contact with Dale Dougherty, who invented not just “Web 2.0” but also the “Maker Movement” and Make Magazine. Arduino and Make was a match made in heaven, and the rest is history.

But as mentioned at the top of the article, this is a classic tale of woe. Banzi had better connections and more marketing drive and skill. He pushed the exact same project — rebranded — a lot harder, better, and further than Barragán did, or probably could. Arduino is a household name simply for that reason. If Massimo Banzi hadn’t been behind the wheel, it’s unlikely that you’d be complaining about how many Wiring-based projects we feature.

And, being open-source software and hardware, Barragán gave away the shop. He probably (naïvely) expected to get more credit from his former advisor, or even get invited along on the ride. He asks why Arduino forked Wiring instead of continuing to work with him, and the answer is absolutely clear — Arduino was taking it for their own. And they could. It’s not nice, but that’s business.

Still, we feel Barragán’s pain. So we’re glad, after a decade of silence, that Barragán is speaking out on behalf of himself and Wiring, because it sets the record straight and because his project really was “Arduino” before there was an Arduino.

Create

A few months have passed from the launch of the internal betatesting of Arduino Create. We are finally ready to open up the number of people who can use and experiment with this online platform. Today each betatester currently in the program has received 5 invites to get other Arduino tinkerers on board, we have also added about 100 people who tried the platform during Maker Faires and other events, or expressed interest online.

Most importantly we have a public waiting list for anyone who wants to try Arduino Create before hand and give us feedback.
You can SIGN UP herethe first 100 people will receive an invite right away, we will add the other subscribers as the betatesting unfolds.

What’s new?

The Arduino Create Editor has most of the Arduino Desktop IDE features, it is a fully functional Editor, and you can start developing your projects on it right away. We are really close on having everything delivered in HTTPS, we are working hard to add the Library Manager and support for all the Certified and AtHeart boards. Next in our roadmap is including a Sharing feature and a Chrome OS plugin.
As already said in the past, we are always going to provide our community with a offline solution, so don’t worry :)

When you use Arduino Create for the first time you will be prompted to install a plugin (agent). While your Sketchbook and the apps are hosted in the Cloud, the plugin will locally check the USB ports on your computer. The plugin detects if any board has been connected, if you are uploading a sketch, or you are using the Serial Monitor. The Arduino Create agent is open-source, and available for Mac, Windows and Linux! If you find it interesting you can contribute to it or fork it to use it in your projects.

We are currently working on a brand-new tutorial platform, Arduino Create Projects, in collaboration with Hackster.io. We are planning to release it at the beginning of 2016. Arduino users will finally have a place where they can share their own projects and include step by step guides, schematics and layout references, pictures, videos, the code they wrote, and useful links and comments. We can’t wait to share it with you all so stay tuned!

Today we are very proud to release Arduino IDE 1.6.6 and updated cores for all supported platforms (AVR 1.6.9, SAM 1.6.5, SAMD 1.6.2)

This update brings an impressive 723 closed issues and 147 pull requests merged.

Most intriguing features are:

  • Long-awaited new arduino-builder: this is a pure command-line tool which takes care of mangling the code, resolving library dependencies and setting up the compilation units. It can also be used as a standalone program in a continuous-integration environment
  • Pluggable USB core: your Arduino can finally act as a lot of different USB devices without any need to change the core, thanks to the new modular architecture. Libraries based on the new subsystem are already being developed!
  • Serial plotter: you can now plot your data in realtime, as easy as writing Serial.println(analogRead(A0)) inside your loop
