If you enjoy model rocketry, you may wonder just what the thrust curve of the motors you’re using looks like. In order to answer that question, YouTuber ElementalMaker decided to construct his own test stand using an Arduino Uno coupled to...

Sensors like the TCS34725 from Adafruit can detect a single color. It stands to reason then, that if you were to aim this sensor at a multitude of points and record the resulting data, you could have a one-pixel camera....

Drones come in many shapes and sizes, but for the most part their motor pods are fixed during flight. Inspired by the way birds can fold their wings, researchers from the University of Zurich and EPFL have come up with...

All of us have daily tasks we need to perform, but what if you often forget whether you’ve done something, or simply need to give your child a little extra motivation? One great way would be Simon Prickett’s Arduino Task...

Six-legged robots are nothing new, but if you’d like inspiration for your own, it would be hard to beat this 22 servo-driven, 3D-printed hexapod from Dejan at How To Mechatronics.  The ant-inspired device features three metal geared servos per leg,...

LED strips reacting to sound is nothing new; however, Paul Shulman’s setup does things a bit differently. Instead of responding to the tune’s overall volume, one musical frequency is analyzed and averaged; if the intensity changes sufficiently on that particular...

What do you do when you need to attach 400-500 screws for an upcoming project? If you’re “Progress Thailand” you simply create one yourself using a 9g micro servo modded for continuous rotation, an Arduino Nano, and some 3D printing! The...

Bigger isn’t always better, as illustrated nicely by this device from YouTuber “Volos Projects.” It’s not only physically quite small, squeezing an Arduino into a 40x25x25mm aluminum enclosure, but uses an interface consisting of a single button (plus a power...

In the build shown below, Evan McMahon dares to ask the question, “Have you ever been disappointed by a mood ring?” While that might seem a bit random, the answer is a likely “yes” if you’ve ever worn one with...

As first reported by the Des Moines Register, this year 14-year-old Josiah Davenport decided to animate 3,500 Christmas lights on his family’s home with the help of an Arduino Mega. The lighting pattern is synchronized with the Trans-Siberian Orchestra’s “Wizards...

It’s that time of year again, when many the world over chop down a tree, then insert it into some sort of water dish to keep it green for a month or longer. This normally works out well, but means...

You may have come across the term “PID control,” and while this proportional-integral-derivative control method does a great job of smoothing out oscillations, where does one get started?  One solution would be Mr Innovative’s demo device, showcased in the video...

While we don’t normally think of typing on a computer as a dangerous job, the U.S. Department of Labor reports that workers spend 25,000 hours away from work due to repetitive strain injuries, such as using a computer. Part of this...

Aseen here, Bit by Jonghong Park at the University of the Arts Bremen is a beautiful visualization of how everything is linked together using the Markov chain principle. This installation uses an Arduino Mega for control, rotating arms that hold a pair of...

Of course Styrofoam floats on water, but have you ever seen it float in midair? That’s exactly what Julius Kramer’s 3D-printed acoustic levitator does, using an array of 72 40kHz ultrasonic transducers to form standing waves of low and high...

Omni wheels are devices that look like wheels with extra rollers positioned along their circumference. This allows robots to move forwards and backwards, as well as slide and spin depending on how the wheels are powered. Maker Jeremy S. Cook...

Chris Lovett used a cheap remote plug to control his Christmas lights; however, when the fob’s A53G 12V battery died, he decided to go a different direction. Rather that just replace the battery, he hooked up an Arduino Leonardo for...

Weather reports on the news, your computer, or smartphone are very good—something that people 100 years ago could only dream of—but what if you want to know the exact weather in a fixed location from anywhere in the world? One...

While once an essential communication tool, rotary phones in the wild are quite a rarity today. Still, they do hold a certain charm, and hacker Kristiaan N. decided to turn one of these units into a clever home automation interface....

A needle and thread is extremely useful if you need to fasten a few pieces of fabric or sew on a button, and a sewing machine takes things up several notches in speed an accuracy. This venerable machine, however, can...

3D printers get most of the attention in maker-fabrication news, but other computerized tools, like laser cutters and CNC routers, can also be extremely useful. In fact, Nikodem Bartnik decided to create his own Dremel-based machine constructed out of 3D-printed...

In order to inspire the next generation of scientists and engineers, Michael Graham (AKA EngineerDog) has come up with a robot that automatically draws on coffee mugs with a marker—and potentially much more.  In its nominal configuration, the Mug-O-Matic is...

While the world seems to be focusing on self-driving cars, maker Sieuwe Elferink has instead turned his attention to creating a semi-autonomous kids’ four-wheeler. As of now, the modified device can steer itself within a set of lines, and stop...

Halloween has become something of a hacker holiday, giving creative people the world over a chance to show off their spooky animatronic inventions outside without neighborhood scrutiny. This year, Instructables user “gocivici” created a display inspired by the doll in...

We are very happy to announce the Arduino PRO Gateway for LoRa! Combined with Arduino MKR WAN 1300 IoT nodes, it makes an ideal solution for a wide range of applications, like smart agriculture, smart cities and building automation – and...
