Loop antennas for ham radios use heavy duty variable capacitors for tuning. Since such capacitors need to be physically turned for adjustment, radio enthusiast Jose B.O. made his own remote rig using an Arduino Uno and CNC shield. The CNC setup allows stepper motors to rotate through a range of angles for frequency selection, and […]
It’s been a long time since we first launched our Arduino IDE inspired by the glorious Processing interface, and what started as a Java UI wrapper for build scripts has gone through countless iterations over the past fifteen years. Some may remember the transition between 1.0 and 1.5, or the application’s icon being replaced, but […]
If you want to “enhance your athletic training regimen,” or perhaps just have a bit of fun with robotically launched ping pong balls, then be sure to check out the Pingo apparatus shown in the video below. This robot moves back and forth on four DC motor-powered wheels, searching for targets with an ultrasonic rangefinder. […]
Touching your face is a subconscious behavior that we all do, and it is also an easy way to pick up illnesses like the coronavirus and flu. However, like many infectious diseases, proper hygiene can help reduce your risk. With this in mind, Nick Bild designed a simple solution in the form of a modified […]
When you step out in public, you’ll often be filmed by a number of cameras and perhaps even be analyzed by tracking software of some kind. The Watchman robot head by Graham Jessup, however, makes this incredibly obvious as it detects and recognizes facial movements, then causes a pair of eyeballs to follow you around. […]
After being given a 2009 MacBook, John Forsyth decided to use it to start a 1976 Jeep via voice control. The build uses the laptop’s Enhanced Dictation functionality to convert text into speech, and when a Python program receives the proper keywords, it sends an “H” character over serial to an Arduino Uno to activate […]
This is a guest post from Surrogate, a team of developers building games that people play in real-life over the internet. We introduced this concept last year, and have launched three games so far. Our final game of 2019 was SumoBots Battle Royale — where players from anywhere in the world can fight real robots […]
Music and synchronized lighting can be a beautiful combination, evident by panGenerator’s recent installation that was commissioned by the Meskie Granie concert tour in Poland. The interactive sculpture was comprised of 15 drums that trigger waves of light traveling toward a huge helium-filled sphere floating above the area, appearing to charge it with sound and […]
This post is from Massimiliano Pippi, Senior Software Engineer at Arduino. The Arduino IoT Cloud platform aims to make it very simple for anyone to develop and manage IoT applications and its REST API plays a key role in this search for simplicity. The IoT Cloud API at its core consists of a set of […]
If you have multiple applications open in Windows, you may want one to be louder than the other, but what if you want to adjust levels with physical sliders like an actual DJ? If that sounds interesting, check out this controller by “Aithorn.” The device uses an Arduino Nano to read signals from each slider and […]
