The ArduINA226 is an Arduino-based power monitor

From blog.arduino.cc 2 years ago in Platforms Stores

Giovanni Carrera has created a capable power monitor, dubbed the ArduINA226, using an Arduino Nano and an INA226 IC. This chip measures the current and voltage, and calculates power, which is then read by the Arduino board and sent to an LCD display. The unit also features a micro SD...

Building the worst digital camera ever

From blog.arduino.cc 2 days ago in Platforms Stores

Digital cameras work by letting light through a lens onto a sensor composed of photosites, each with a photodiode that outputs a signal relative to the brightness of the light. Modern digital camera sensors have millions of photosites, each of...

Real Robot One is a high-performance robotic arm that you can build yourself

From blog.arduino.cc 2 days ago in Platforms Stores

Robotic arms are versatile machines and are great for learning about principles of robotics or even doing useful work for hobbyists. That work might be picking and placing components on PCBs, packing boxes, or anything else you can imagine. But...

Reading analog gauges with the Nicla Vision

From blog.arduino.cc 5 days ago in Platforms Stores

Analog instruments are everywhere and used to measure pressure, temperature, power levels, and much more. Due to the advent of digital sensors, many of these became quickly obsolete, leaving the remaining ones to require either conversions to a digital format...

This snake robot is large enough to ride upon

From blog.arduino.cc 5 days ago in Platforms Stores

If a robot is rideable, is it still a robot or is it a vehicle? We would argue that if it rolls on standard automobile-style wheels or even tank tracks, it is a vehicle. But James Bruton’s eight-wheeled robot snake...

A wearable, waterproof, wireless human-machine interface

From blog.arduino.cc 1 week ago in Platforms Stores

“Human-machine interface” (HMI) is a general term that describes any physical input or output hardware that people can use to interface with systems (like computers) and vice versa. That very broad definition usually applies to computer input devices like keyboards...

Affordable CAT scan machine built with an Arduino

From blog.arduino.cc 1 week ago in Platforms Stores

A CT (computed tomography), or CAT (computed axial tomography), scan is a type of medical imaging technique in which multiple X-ray “slices” come together to form a pseudo-3D model. CT scanners are the kinds of medical equipment that are so...

Building a DIY laser modem

From blog.arduino.cc 1 week ago in Platforms Stores

All digital communication ultimately comes down to transmitting ones and zeroes, but there are many ways to achieve that. One can encode that binary data as modulation in a radio signal or simply pulse electricity through a wire. But one...

This high-precision AC meter handles inductive loads

From blog.arduino.cc 2 weeks ago in Platforms Stores

AC (alternating current) meters are useful tools for measuring power draw. One might use an AC meter to monitor the power consumption of their devices and appliances with the goal of lowering their energy bill. Makers in particular can benefit...

Over-engineered robotic scalp scratcher knows all the moves

From blog.arduino.cc 2 weeks ago in Platforms Stores

Those cheap wire-arm head massagers are great at giving your scalp a nice, relaxing rub. But they’re handheld implements that force the user to either manipulate the massager themselves or talk a partner into performing the task. David McDaid decided...

LEGO-firing turret targets tender tootsies

From blog.arduino.cc 2 weeks ago in Platforms Stores

Stepping on LEGO bricks is a meme for a reason: it really @#$%&! hurts. LEGO brick design is ingenious, but the engineers did not consider the ramifications of their minimalist construction system. We’ve seen people do crazy things for Internet...
