This device by Dejan Nedelkovski of How To Mechatronics implements both an ultrasonic sensor for range measurement and an accelerometer for measuring angles. While you’ve likely seen these implemented separately in other projects, combining them saves space, and allows the Arduino Nano onboard to use the two readings together to calculate a square area automatically.
If you have young kids, you’ve probably realized that they don’t exactly like to sleep in. While their energy levels are enviable, if their clock-reading skills haven’t yet caught up, this device by maker “JonathonT” looks like a great and simple solution.
Graduate students Ben Wiener and Philip Zucker have been working on a classic controls problem for quite some time called an “inverted pendulum.” This type of device balances a stick on an axis, and in this implementation, a motor pulls the axis assembly that the pendulum—a paint stirrer—is sitting on to keep it stable.
We’re excited to kick off Maker Faire Bay Area by expanding our IoT lineup with two new boards: the MKR Vidor 4000 and the Uno WiFi Rev 2.
If you need a way to restrict access to power tools to only authorized users, Casey Horton’s magnetic card reader setup, shown in the video below, looks like a great solution.
The first of the boards is the MKR WiFi 1010, which offers low power consumption and has been designed not only to speed up and simplify the prototyping of WiFi-based IoT applications, but also to be embedded in production IoT applications that require WiFi connectivity.
We’re excited to announce the Arduino Engineering Kit, the first product released as a result of our new partnership with MathWorks, to reinforce the importance of Arduino at the university level in the fields of engineering, Internet of Things, and robotics.
About a month ago we started livecasting from Arduino’s YouTube channel. This is something I had been willing to do for quite some time, but I never figured out the way to make room in my agenda to fit the planning required to make it happen.
Digital music—which gives us access to a virtually unlimited amount of media at our fingertips—is an amazing innovation. On the other hand, if you get nostalgic for something a bit more tangible, this “Victrola for the 21st century” may just fill that gap.
As seen here, although you might consider your oscilloscope and other test equipment to be pretty neat, you most likely don’t have anything nearly as cool as the scanning electron microscope that was dragged out of a shed at Benjamin Blundell’s local hackerspace.
Graffiti with spray paint is generally impolite and illegal, but as hacker “Reven” shows in his write-up, you can get a very similar effect with long exposure photography and carefully-timed LEDs.
Wile we know on some level that prices adjust to market conditions, with Amazon now owning Whole Foods, one could perhaps see a day when this happens electronically and instantaneously.
If you ever find yourself needing someone to talk to and can’t find a confidant—or perhaps even a pet—then the Eve chatbot by Debashish Buragohain will happily fill in.
This little robot uses Google Voice Recognition on an Android phone to listen to what you say and convert it to text, then pipes it over to the Arduino-based robot via Bluetooth.
