On April 1st, Arduino Day was celebrated by more than 499 communities in 79 different countries, with official events held in Turin, Malmo and San Jose.

In Turin (photos can be found here), Massimo Banzi and Federico Musto unveiled the latest developments of the Arduino platform, including products like the MKRFOX1200, NFC Shield, LoRA Gateway Shield, LoRA Node Shield, as well as the Casetta and Libretto Kits. Moreover, they also highlighted new improvements to Arduino Create, particularly its expansion to Chromebook users, and recent advancements of Arduino’s educational project, CTC.  

Weren’t able to tune in to our live stream? Watch the video below to catch all of the day’s talks by various members of the Arduino team.

Most importantly, we would like to express a heartfelt thanks to our extremely passionate and awesome community. It was YOU who made Arduino Day a huge and successful celebration we will never forget.

Now on Kickstarter, ArduECU is an IP69K-rated waterproof, rugged and impact-resistant electronic control unit (ECU) that enables your Arduino projects to withstand the elements and other harsh environments.

ArduECU is compatible with all 12V to 24V systems, and can be used in a wide range of applications such as vehicle diagnostics and control, stationary machines, remote monitoring, industrial automation, and agriculture to name just a few.

Based on an ATmega328, the ECU can be programmed with the Arduino IDE and also supports CoDeSys, meaning you can now configure your ArduECU with ladder logic, functional block, structured text, instruction list, or sequential function charts.

ArduECU comes in three models–one for basic projects, one for CAN bus vehicle and machine control applications, and another which converts an existing Arduino Uno into a weatherproof, custom-tailored ECU with an on-board prototyping area for your own creations and circuits. Each of these units will have expansion headers to leverage IoT and wireless capabilities, including Wi-Fi, Bluetooth, cellular and GPS, or to house future expansion shields with additional functionality at a later time.

Jonathan Odom, a full-time designer at Instructables who goes by the name “JON-A-TRON,” decided to make a clock illustrating time’s linearity.  What he came up with was a beautifully crafted (robotically manufactured at the Pier 9 workshop, that is) clock that uses two rack and pinion assemblies to move a line of numbers for hours on top of another line signifying minutes.

The minute “hand” is divided up into five-minute intervals, which seems to him to feel less neurotic than being precise down to the exact minute. Magnifying glasses are used to magnify an hour and minute number, reminding onlookers to focus on the present.

The clock is actuated using an Arduino Uno with a motor driver, controlling a stepper motor for each “hand.” It’s an incredible build, and nicely illustrated. Whether or not you have access to the tools needed to recreate this exact clock, perhaps this concept will inspire something similar!

Be sure to check out Odom’s clock Instructables write-up here and see a demo of it below!

As Arduino Day quickly approaches, we are blown away by the tremendous support of the Arduino community with more than 480 events from all around the world.

Arduino Day Turin will feature talks by Massimo Banzi, Federico Musto, and other Arduino members, which will be streamed live on the Arduino Facebook, Twitter and YouTube channels. The streaming will begin at 3pm CET. A final program of presentations will be posted as soon as possible at this link. Starting at 11am CET at Toolbox Turin, the agenda will include: two workshops for children in collaboration with Fablab for Kids (registration here and here), a basic and an advanced workshop for adults in coordination with the Casa Jasmina crew (registration here and here), as well as a young Maker activity corner supported by Codemotion Kids. Everything will be free of charge.

Arduino Day Malmö festivities (full program here) will consist of an Arduino project showcase, a panel of discussions with David Cuartielles and local Makers, in addition to a pair of free activities for kids (registration is not necessary). Starting at 5pm, there will also be a live streaming of the talks from Arduino Day Turin.

Last but not least, the Arduino team will be hosting a third official event in San Jose, CA (register here). The program will kick off with a demonstration of Arduino projects, followed by a live video exchange with Arduino Day Toronto. This is a great opportunity for Arduino enthusiasts in America to socialize with one another, exhibit their latest creations, and even learn more about Arduino in the classroom. Everyone is welcome to attend!

We cannot wait to celebrate with our community this Saturday! Until then, continue sharing your plans and inviting your friends to join Arduino Day via social media using the hashtag #ArduinoD17.

Using an Arduino, wildlife observer and hiking hacker Andrew Quitmeyer modified a spherical camera to take pictures when motion is detected.

If you’d like to photograph wildlife without actually being there to scare the animals off (or because you would eventually get bored), a great solution is a camera trap. These devices can trigger a camera when animals move nearby, hopefully capturing interesting images. Generally, you need to point your camera in the right direction, but Quitmeyer got around this by using a 360 camera instead to eliminate this placement bias.

In order to control the device, he rigged up his own system with PIR motion sensors and an Arduino Uno to prompt the camera as well as power it on and off. The hack looks effective, though voiding an expensive camera’s warranty like this will certainly scare a few Makers off!

You can see more about how this project was pulled off on Instructables, and find the Arduino code used on GitHub.

Pete “Raster” Prodoehl shows how to test microswitches with an Arduino Uno.

As referenced in his write-up, Prodoehl needed a way to test microswitches that he’d be using for an exhibit. After all, when something is on display, the last thing you want is to have to replace components. Inspired by how Consumer Reports tests things, he decided to build his own setup with a counter and 3D-printed “pusher.”

What he found was that when you’re testing the life span of a component made to work over and over, your testing components have to also be robust enough to handle the very gradual abuse. It’s an interesting exercise, and something that engineers in manufacturing have to deal with constantly. Getting something to work once or even a times is neat, but getting it to function thousands of times for a test or otherwise takes a different way of thinking!

You can see more about this project on Prodoehl’s page here, and check out the video compilation below for a quick overview.

If you want a light-up dance floor for your next wedding or other special event, you can rent one; however, that can be quite expensive. On the other hand, you and your hacker friends can always build one. How hard can that be?

Turns out, very hard. While it may be simple to get one translucent panel to illuminate with LEDs, this 17-square-foot interactive dance floor used 64 panels with four lighting cells in each, for a total of 256 lighting arrays and 7,680 RGBs arranged as 2,560 addressable pixels.

Even with some advanced tools like a pick-and-place machine for PCB manufacturing, as well as a laser cutter, it still took volunteers many hours over the course of 11 months to get it working. LED control is accomplished via a Teensy 3.1, while 256 pressure switches under the surface are read by an Arduino Mega.

You can see more details of the impressive project in the video below (including a round of multi-player Dance Dance Revolution) and a few more technical details in AvBrand’s write-up here.

Tadej Strah, a freshman at Gimnazija Vic in Slovenia, made a motorized gimbal using only $60 worth of parts.

After joining a photo and film club at his university, Strah was inspired by a member with cerebral palsy to build an inexpensive gimbal to keep a small camera level. His project uses an MPU-6050 sensor to detect motion, and an Arduino Mega to process this data and control the device’s two servos. The setup includes a handle from an angle grinder, while the servos are mounted on bent pieces of metal, helping keep the cost down.

Strah believes that with a few upgrades, such as a smaller battery, Bluetooth connectivity, and a 3D-printed frame, it should be able to provide many of the features of those available for $500 or more. Hopefully we’ll see this design become even better in the future!

Until then, you can follow along with Strah’s progress, and perhaps another iteration of his gimbal, on his YouTube channel.

Silencing a smartphone at night isn’t difficult, but if you have a landline, Arduino can help!

Before computer hacking/modding became accessible, the next best thing was to creatively explore the phone system via custom electronics. Though this pursuit, known as “phone phreaking,” has largely gone away, some people still have landlines. As “MolecularD” shows in this Instructables writeup, with a few components you can creatively trick your phone into not ringing on your end, while appearing to the caller to simply ring and ring as if no one is home.

In order to make it much more useful, MolecularD hooked up an Arduino Mega with a real-time clock module to turn the device on and off depending on the time of day. Now calls from phone solicitors, or “IRS agents” at 4 in the morning can be eliminated automatically. As noted, this may or may not be legal where you live, so attempt it at your own risk!
