For years, the open-source philosophy of Arduino has been the inspiration to robots, drones, medical and space research, interactive art, musical instruments, 3D printers, and so much more. Now, Arduino is on a mission to radically simplify the way you build smart devices. Introducing ESLOV, a revolutionary plug-and-play IoT invention kit.

ESLOV consists of intelligent modules that join together to create projects in minutes with no prior hardware or programming knowledge necessary. Just connect the modules using cables or mounting them on the back of our WiFi and motion hub. When done, plug the hub into your PC.

ESLOV’s visual code editor automatically recognizes each module, displaying them on your screen. Draw the connections between the modules on the editor, and watch your project come to life. From there, publish your device to the Arduino Cloud and interact with it remotely from anywhere (including your phone). The Arduino Cloud’s user-friendly interface simplifies complex interactions with sliders, buttons, value fields, and more.

The ESLOV modules and hub can also be programmed with the wildly popular Arduino Editor — you can use either the online editor or the desktop-based IDE. With the provided libraries, you can customize the behavior of the existing modules, enhance the hub’s functionalities, as well as modify the protocols of both the hub and the modules.

With a total of 25 modules — buttons, LEDs, air quality sensors, microphones, servos, and several others — the possibilities are endless. Sample applications include everything from a monitor that lets you know if your baby is safe, to a washing machine notifier that tells you when your laundry is finished, to a thermostat that you can adjust while out of the house.

In line with the core values of the Arduino community, ESLOV’s hardware and software are open-source, enabling you to produce your own modules. Additionally, Arduino will welcome third-party modules from partners and other certified programs.

To accelerate its development in the open-source spirit, ESLOV — which began as part of a three-year EU-funded PELARS project — is now live on Kickstarter and needs your support.

The toolkit is offered in a variety of sizes, depending on the number of modules. Prices range from ~$55 USD to ~$499 USD, with multipacks and other opportunities available as well. Delivery is expected to get underway in June 2017.

In terms of hardware, the main hub is currently equipped with a Microchip SAM D21 ARM Cortex-M0+ MCU at 48MHz and built-in WiFi (just like the MKR1000). Each of the modules are small (2.5 x 2.5cm), low-power (3.3V), single-purpose boards featuring the same processor found at the heart of the Arduino/Genuino UNO: Microchip’s ATmega328P.

The modules can be reprogrammed via I2C bus or with an external programmer. ESLOV’s hardware includes firmware from our factory, dedicated to the specific function of each module.

The ESLOV connector has five pins (one more than standard I2C) for automatically configuring the module and handling the sleeping states to boost battery life. Tests can be performed on your computer via USB. The modules’ firmware and the hub’s software can be updated both using the USB cable and over-the-air (OTA).

Those heading to World Maker Faire in New York on October 1st-2nd can learn more about the kit inside the Microchip booth in Zone 3, as well as during Massimo Banzi’s “State of Arduino” presentation on Saturday at 1:30pm in the New York Hall of Science Auditorium.

[Aleksejs Mirnijs] needed a tool to accurately measure the power consumption of his Raspberry Pi and Arduino projects, which is an important parameter for dimensioning adequate power supplies and battery packs. Since most SBC projects require a USB hub anyway, he designed a smart, WiFi-enabled 4-port USB hub that is also a power meter – his entry for this year’s Hackaday Prize.

[Aleksejs’s] design is based on the FE1.1s 4-port USB 2.0 hub controller, with two additional ports for charging. Each port features an LT6106 current sensor and a power MOSFET to individually switch devices on and off as required. An Atmega32L monitors the bus voltage and current draw, switches the ports and talks to an ESP8266 module for WiFi connectivity. The supercharged hub also features a display, which lets you read the measured current and power consumption at a glance.

Unlike most cheap hubs out there, [Aleksejs’s] hub has a properly designed power path. If an external power supply is present, an onboard buck converter actively regulates the bus voltage while a power path controller safely disconnects the host’s power line. Although the first prototype is are already up and running, this project is still under heavy development. We’re curious to see the announced updates, which include a 2.2″ touchscreen and a 3D-printable enclosure.

Bluetooth Low-Energy (BLE) is a great bluetooth solution for your electronics product even if energy use isn't a factor.

In this video, our friends at PubNub are going to create a smart home network that builds upon their previous Johnny Five tutorial. They again hack an Arduino Uno using JavaScript, but this time to create the simplest smart bulb. Because by “smart bulb,” we really just mean an LED.

The tutorial was developed by Tomomi Imura from PubNub and also uses Johnny-Five. No, not the robot from the movie Short Circuit. It is an open-source JavaScript robotics framework that lets you program an Arduino with Node.js. The bulb itself is remotely controlled via a web portal.

To establish the realtime communication between the Arduino and a web browser, the PubNub Data Stream Network (DSN) is used. PubNub provides global infrastructure and allows you to build and scale real-time apps and IoT devices quite easily.

The remote controller (web app) is written in JavaScript. This is a simple user interface that includes only one button. While a completed code sample is available on CodePen, this tutorial employs a simplified version so that it’s easier to follow along.

Interested in the world of hardware hacking, but feeling left out because you just don’t have the time to learn another language? Or maybe you aren’t comfortable using Sketch to program? Have no fear, you can easily use JavaScript to program boards like Arduino and Genuino. Yes, just JavaScript!

In this series of video, PubNub’s Tomomi Imura shows you how to start hacking an Arduino with Node.js using Johnny-Five, a JavaScript Robotics Framework.

Part one of this tutorial covers:

1. Setting up a board.
2. Building the Hello World of hardware, a LED blink.
3. Writing your Johnny-Five code to make it blink programmatically.

Enjoy the tutorial!

If necessity is the mother of invention, then inconvenience is its frustrating co-conspirator. Faced with a finicky dryer that would shut down mid-cycle with a barely audible beep if its load was uneven (leaving a soggy mass of laundry), [the0ry] decided to add the dryer to the Internet of Things so it could send them an email whenever it shut itself down.

After opening a thinger.io account, adding the soon-to-be device, and setting up the email notification process, [the0ry] combined the ESP8266 Development Board, a photosensitive resistor, and a 5V power supply on a mini breadboard. All that was left was to mount it on the dryer and direct the LDR (light-dependent resistor) to the machine’s door lock LED to trigger an email when it turned off — indicating the cycle had finished or terminated prematurely. A little tape ensured the LDR would only be tripped by the desired light source.

If you’re an apartment-dweller have WiFi in the wash area it would be awesome to see a battery-powered version you take with you. But in general this is a great hardware blueprint as many device have status LEDs that can be monitored in a similar way. If you want to keep the server in-house (literally in this case) check out the Minimal MQTT series [Elliot Williams] recently finished up. It uses a Raspberry Pi as the center server and an ESP8266 is one of the limitless examples of hardware that plays nicely with the protocol.

We love seeing hacks like this because not only does it conserve water and energy by reducing instances of rewashing, but it’s also a clever way to extend the life of an appliance and potentially save hundreds of dollars in replacing it. Add this to the bevvy of hacks that add convenience to one’s home — some of which produce delicious results.

During a recent workshop, Swedish innovation studio Topp set out to create a platform for rapid prototyping with design and data. The team decided to take an existing product and retrofit it with IoT capabilities. For this, they selected an IKEA Spöka night light and hacked it with an Arduino MKR1000. The connected lamp is capable of reacting to its surrounding environment through sound, motion, and light, while an accompanying app is used to monitor and control intensity.

Traditionally data and physical interactions have been difficult to work with, often requiring the availability of early hardware or by constructing mockup data. However, to achieve quick iterations and a higher fidelity experiences for projects involving data, sensors, cloud, and other things typically unavailable to designers early on in projects, we’ve developed a tool called Noodl to help support a better way of working. We’re using Noodl as a foundational tool when we hack our night light.

A key function for this hack is to have the lamp and the phone connected to an IoT cloud broker. Bluetooth or other non-routable communications would not work with remote presence, so by using Wi-Fi and a public broker we could build a prototype that also works with multiple clients in a true IoT fashion.

The end result was a platform that makes use of cloud and data, which could be employed for a wide range of intelligent home devices ranging from a baby monitor to a morning alarm to a smart dimmer. You can read all about the project — along with instructions, code and components — on Topp’s page here.
