YouTuber “The Mixed Signal” has come up with a fun way to make music: spinning a gear-like ferromagnetic tonewheel next to a homemade coil pickup.  A stepper motor turns the wheel using a CNC shield under Arduino control. When set...

Trigonometry is a struggle for some students. Perhaps one of the reasons for this is that instruction can be something of a one-way street, and concepts can be hard to grasp until more technical building blocks are learned.  As seen...

We’re just days away from Maker Faire Rome — The European Edition, taking place October 18-20th at Fiera di Roma. This year’s Arduino booth, which will be located inside Pavilion 8, will be broken up into three areas: Education: We...

This post was originally published by Sandeep Mistry and Dominic Pajak on the TensorFlow blog. Arduino is on a mission to make machine learning simple enough for anyone to use. We’ve been working with the TensorFlow Lite team over the...

Software engineer Josh Robertson decided to come up with his own take on a marriage proposal, building a reverse geocache device for the job that uses not one, but two Arduino Uno boards.  The unit, which is made out of...

Normally guitar pedals take in a signal from your instrument, then some modification to an amplifier. ElectroSmash’s open source device, however, looks like a guitar pedal, connects to a guitar and amp like a guitar pedal, but actually leaves the signal unmodified....

Engineers at the University of California San Diego have come up with a way to build soft robots that are compact, portable and multifunctional without the requirement for compressed air.  Instead, they’re using a system of tubular actuators made out...

As shown in the video below, Tristan Calderbank is a very talented singer and guitar player, but what’s perhaps most interesting about his performance is the percussion section. Instead of a person (or an entire band) standing beside him, a...

We’re excited to announce the launch of the Arduino MKR WAN 1310, which offers a practical and cost-effective solution for those looking to add LoRa connectivity to their projects.  The new MKR WAN 1310 enables you to connect your sensors...

Planning to attend Maker Faire Rome later this month? We’re currently seeking volunteers to join our team during the event—staffing tables and displays, helping with demos, and providing technical assistance when necessary. If you volunteer with us for one shift,...

Vacuum fluorescent displays (VFDs) have a distinct cool blue-greenish glow, and were once used in a wide range of devices, from VCRs to microwave ovens and even car dashboards. Although extremely popular way back when, they can be more difficult...

If you fly drones for fun—or perhaps even for work—you know that piloting them can sometimes be a difficult tasks. Imagine, however, trying to control four drones simultaneously. While also “challenging,” researchers at the Skolkovo Institute of Science and Technology...

Drowning is the third leading cause of accidental death in New Zealand, and the vast majority of lifeguard rescues are due to rip currents—hard to observe unless you’re already in peril. In order to help fix this problem, Victoria University...

Joop Brokking has been experimenting with a miniature candle-powered steam engine. It’s an amazing little device, able to push a piston over and over to turn a flywheel, releasing the steam via a mechanically-controlled valve. But just how fast does...

YouTuber Oracid1 has developed a unique family of four-legged robots, dubbed “FiveBarQuads.” The quadrupeds all feature ultrasonic sensing for navigation and a body made out of LEGO components — and as seen in the first video below, his latest (and...

Non-profits can do great work, and in order to help others visualize the needs they serve and what they are doing, Jason Wolin came up with an amazing map for his organization. The massive map stretches down 14 feet of...

Richard of ARITH-MATIC had the idea to build a 4-bit computer based on 7400 series ICs (like the 74HC273, 74HC193, and 74HC125), but other responsibilities got in the way of this becoming a reality for quite some time. Finally, with...

Do you need a small weight scale? You can of course buy one, or you could instead make your own 3D-printed device with a load cell and an Arduino, as shown in the below video by MN Maker. In his...

What really happens when you open the refrigerator door? Sure, you know intuitively that cold air escapes, but just how much? And how fast does the food inside actually heat up? To find out, Ryan Bates came up with his...

As a kid you may have played Operation, but certainly never anything like this nine-foot-tall version from SPOT Technology. This device is not only impressively large, but assists doctors in their surgical pursuits with a CNC gantry setup to pull out...

Spilled wine may be a hassle to clean up, but you might also observe that it makes interesting patterns. Marketing firm KPS3 had the same kind of thinking when they designed the web-controlled “Swirl Machine” to promote the Santa Maria...

You’ve seen barcode scanners register the price for your groceries, and likely in many other applications, but did you ever consider if one could be made into an instrument? Well we now know the answer, thanks to this MIDI guitar...

Hearing live music is certainly enjoyable, but if the musician is using a drum machine, things can eventually get static. To add a bit more spontaneity into this class of robo-musician, Matt Bradshaw has created DrumKid — a handheld, battery-powered...

Remembering to refill water and coffee cups at regular intervals certainly has to be a challenge for restaurant waitstaff, but not for servers at one diner thanks to Mark Wilson’s “TetrisWaterRun” project. Wilson’s device takes the form of a miniature...

Hey Arduiners, Today we are releasing IDE 1.8.10 and you should try it because it’s awesome! With the support of our incredible community, we’ve been improving a lot of (small and not so small) things. Besides taking a look at...
