After being inspired by a beautiful, if rather expensive timepiece, Ira Hart decided to make a 3D-printed clock with 24 analog faces that combine to form a single digital display. The overall device is controlled by a single Arduino Nano, which keeps track of the time using a RTC module. This unit coordinates 24 other Nanos […]
Every year, one of Arduino Day’s biggest highlights is the Community Challenge, and 2021 is no different. As you read this, we’re working feverishly behind the scenes to get this year’s challenge ready, so you can start submitting your projects for a chance to win some awesome Arduino goodies. Keep an eye out right here […]
As a child, chances are you came across a Lite-Brite at some point. The toy consisted of a light box with small plastic pegs that fit into a panel and lit up to form a picture. Drawing inspiration from that, mechatronics engineer Zach Frew thought “it would be cool to make a robot that consumes […]
Many of us spend all day staring at a computer screen, entering data, watching YouTube, writing blog articles, or any number of other tasks. According to Daniel Hingston, computer-induced eye strain can be a real problem, and to combat this, you should follow the 20/20/20 rule. That is for every 20 minutes of computer time, […]
If you want to upgrade your soldering setup without spending a lot of money, then be sure to check out Angelo Casimiro’s DIY Hakko 907 station. This low-cost device features an Arduino Nano to read the iron temperature via an LM358 op-amp, and regulates power to the handle and tip under PWM control using an […]
If you look at your car’s dashboard, there’s a good chance you’ll find an efficiency rating for how you’re driving. However, what if you instead ride a hoverboard? This functionality is certainly not stock equipment, yet Niklas Roy wanted to understand the power consumption of his transporter during different riding situations. For that reason, he […]
The phenakistoscope was invented in the 1800s as a way to view a series of moving pictures on a spinning disc. While the traditional implementation is ingenious in its own right, Nick Lim has created his own take on this venerable concept, using strobing light to break up frames instead of the slits-and-mirror arrangement of the original. His […]
By popular demand, we are pleased to announce that it’s now possible to buy the Arduino MKR IoT Carrier. Originally forming a key part of the Arduino Oplá IoT Kit, we’ve responded to our community to make the carrier available on its own, thus enabling you to benefit from having a bunch of sensors, actuators, […]
Inspired by persistence of vision (POV) projects, Sagarrabanana built a system that incrementally dispenses water as pixels on a flat surface, creating ephemeral dot matrix messages/images. This so-called “Bikelangelo” device is towed by a bicycle for ultra-mobile marking, and uses a pressurized tank for fluid storage. As he pedals, a series of seven valve open and close under […]
If you want to get better at billiards, the conventional wisdom is to practice. However, if you’re YouTuber Shane Wighton, you build a robotic cue to play the game for you. His device looks like a cross between a pool stick, a sci-fi robot, and a heavily-modified weed wacker. Instead of precisely manipulating the cue, you […]
