Arduino Team — June 6th, 2026 EMI (electromagnetic interference) can be a real nuisance in sensitive circuits. That might be from one device affecting another, but it can also happen when a circuit on a PCB interferes with another circuit on the same PCB (or another PCB in the same device). Engineering to prevent that entirely is really difficult and it helps a lot to be able to see where the interference is, which is why...
Arduino Team — June 2nd, 2026 There was a time when computers were exciting and fun. Now most of them feel like commodity appliances — no more interesting than a washing machine or a toaster. Joe longed for the good ol’ days of 8-bit personal computers, so he used a trio of Arduino development boards to design his own “fantasy computer.” This is reminiscent of fantasy video games consoles, such as the PICO-8. More than anything...
Arduino Team — May 16th, 2026 A few months ago, UncleStem built a completely functional 7:1 scale Arduino UNO Rev3 development board. That was a big hit, for obvious reasons. But what can you do with an Arduino of that size? The answer is: create a matching 7:1 scale turtle robot for it to control. This is a great pairing, because turtle robots are often the first big projects that new Arduino users tackle — usually...
Arduino Team — April 20th, 2026 A single microcontroller can interface with many other components and handle several different tasks — that’s kind of the whole point. But microcontrollers do have limits and sometimes it makes sense to divvy up tasks to get a logical system architecture. That led Michael Rigsby to put a whopping 11 different Arduino boards into his trash-handling robot. This robot, called Zeno, responds to voice commands and can “see” its...
Arduino Team — April 15th, 2026 In the automotive industry, “drive-by-wire” means that a traditionally mechanical linkage, like a throttle cable, has been replaced by an electronic actuator. That can eliminate design constraints and even save money. SciFientist was able to apply those same drive-by-wire principles to this 3D-printed micro milling machine. Machine tools, including vertical mills, are usually either CNC, manual, or power-assisted. In that last scenario, there is usually a simple motor that...
Arduino Team — April 2nd, 2026 Pick and place (PnP) machines are the linchpin on which modern electronics manufacturing rests. A PnP is a special kind of robot with a vacuum end effector designed to pick up SMD (surface-mount device) components and place them on a PCB for soldering. But for hobbyists, they’re usually overkill. So, John LeClair bridged the gap with these manual PnP vacuum tweezers. This is just a PnP machine, but without...
Arduino Days is a great moment to celebrate our community – and what better way to party than with a new product… or seven! During the first day of the event, our team took turns to introduce a variety of accessories and compatible boards you can use in combination with UNO Q and many other elements in our ecosystem, to expand capabilities and make your life easier as an innovator, educator or tech enthusiast. Here’s a quick recap...
Arduino Team — December 28th, 2025 Every millennial knows the exhilarating feeling of going to the computer lab, booting up a Macintosh, and creating beautiful art in MacPaint. The nostalgia meter has broken its dial and is now spinning wildly. If you want to capture that nostalgia in a form suitable for home décor, you can build Mark Wilson’s fantastic LackPaint to display your photos like they’re in MacPaint. LackPaint is basically a digital photo...
Arduino Team — November 25th, 2025 Daric Gill used an Arduino UNO R3 to create his “The Translation Machine” sound art installation for an exhibition at the Dunn Museum. Except he didn’t do it alone, because bees helped with its construction. The Translation Machine is a motion-triggered interactive art piece that plays sounds that Gill collected during his world travels. He recorded those using binaural microphones, which approximate human ears (including the distance between them)...
