Makers, developers and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published to the official Arduino blog, featuring Karl Kristian Torp’s palm-sized Tiny V/A. The Arduino Nano based project takes input from the power supply via a female barrel jack connector. This supplies […]

Useless machines are generally built as a fun pastime, as they do nothing of value by their very definition. The most popular type generally involves a self-cancelling switch. However, there’s plenty of other useless machines to build, and we think [Jeffery’s] build is particularly creative. The build consists of an XY gantry that moves a standard

Despite great progress over the past century, more than a billion people still don’t have access to clean drinking water today. Much of the water on Earth’s surface is polluted, but it’s not always easy to tell a dirty stream from a clean one. Professional kit for water analysis can be expensive, which is why

The official Arduino team has today announced the availability of a new learning resource for those looking to learn more about creating projects using Arduino via the new cloud.arduino.cc website. If you’re teaching electronics or Arduino-based learning you’ll be pleased to know there are lots of projects and instructions on how to get your smart projects connected

Video games are great and all, but sometimes you just want the thrill of manipulating actual objects in addition to watching action on a screen. This must have been the reason why Nintendo’s Duck Hunt became so popular despite the simplicity of its gameplay. Prolific hacker [mircemk] similarly made a computer-plus-physical game called “Laser Shooter“,

We’re all pretty well-acquainted with the obstacle avoiding robot. These little inventions use a proximity sensor to detect an object in front of the robot, then circumvent the object accordingly. Brown Dog Gadgets’ little robot really caught our eye, mostly because it’s kind of cute. This little robot combines a few LEGO pieces, Arduino, and Brown Dog
MAYBE ONE OF THE MOST ADORABLE OBSTACLE AVOIDING ROBOTS YOU’VE SEEN Continue Reading
Seeed has launched a $24.50 “Grove AI HAT” with 6x Grove interfaces and Arduino IDE support for accelerating edge AI workloads on the Raspberry Pi. The HAT features a Sipeed MAix M1 module running a Kendryte K210 RISC-V neural processing chip. Neural acceleration chips seem to be everywhere these days — built into SoCs such
Latest Grove add-on for the Pi includes RISC-V NPU for edge AI duty Continue Reading
Coding wise all good but ive been searching and reading everywhere but still could not find how the HX711 converts voltage coming from the load cell into weight? is there a formula that converts voltage to weight ? if so whatt is this mathematical formula that the HX711 is using?I tried to see if maybe the arduino does the

Electromagnetic interference problems can be a real headache to debug. If you need to prove what causes your WiFi to slow down or your digital TV signal to drop, then the ability to measure electromagnetic fields (EMF) can be a big help. Professional equipment is often very expensive, but building an EMF detector yourself is

Motorcyclist Adnan Khan has decided to use a little Arduino programming and microcontroller hardware to create helmet signalling lights that are linked to the indicators on his motorbike providing other road users with plenty of notification on what is next manoeuvre will be. Watch the demonstration video below to learn more about the project which
