Arduino color picker reveals real world color RGB values

Off the shelf RGB colour pickers allowing you to extract and objects RGB values can range from a few hundred dollars to thousands depending on your needs. If you would prefer to build your very own portable RGB colour picker allowing you to extract colours in RGB valves from real like objects you may be interested in a new project published to the official Arduino blog this week. “If you want a red piece of ...

ARDUINO PEDOMETER COUNTS YOUR STEPS

There’s a trend in corporate America that has employees wear a step counter — technically a pedometer — and compete in teams to see who can get the most number of steps. We wonder how many people attach the device to an electric drill and win the competition easily. However if you want to do your own measurements, [Ashish Choudhary] has plans for making a pedometer with an Arduino. The device isn’t tiny, bu ...

Revolutionizing Electric Field Measuring Techniques

Nowadays, electrical fields are being used not only in electrical engineering, but also for industrial, weather forecasting, safety, and medical applications. As a result, the need for a precise electric field strength measurement device has become increasingly high, and many investigations have devoted their resources to creating such device. TU Wien has developed a small electric field sensor that is much ...

Lie Detector and Biofeedback Arduino Based

This tutorial will explain how to build a machine for biofeedback. But first a bit of theory. What is biofeedback? [Font: Wikipedia | https://en.wikipedia.org/wiki/Biofeedback] Biofeedback is the process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at ...

XMOS VocalFusion- Background Noise Not a Problem Anymore

XMOS is one of the many companies that has ventured in voice recognition technology. They created the VocalFusion XVF3500 device, the first voice processor to have true stereo-AEC support in a far-field linear microphone array solution. Voice recognition is a relatively new technology for consumers which we came to know with Siri, google home, Alexa etc. However, this technology has been developed since 195 ...

MicroZed is a Powerful and Low-Cost ARM + FPGA Linux Development Board

MicroZed is a low-cost development board from Avnet, the makers of the $475 ZedBoard and the entry level MiniZed development boards. Its unique design allows it to be used as both a stand-alone evaluation board for basic SoC experimentation or combined with a carrier card as an embeddable system-on-module (SOM). The MicroZed processing system is based on the Xilinx Zynq®-7000 All Programmable SoC. The Zynq® ...

Transistors- The 70-year-old invention that changed the world

Its been 70 years since the fundamental building block of electronics was created, and it has been getting smaller, and better since then. The invention that won the Nobel prize for John Bardeen, Walter Brattain, and William Shockley in 1956 revolutionized electronics and made it into the IEEE milestone list. Before 1947 computers used vacuum tubes, which could be several inches long, consumed massive amoun ...

ACCESSIBILITY APPS GET HELP FROM BLUETOOTH BUTTONS

Ever hear of Microsoft Soundscape? We hadn’t, either. But apparently it and similar apps like Blindsquare provide people with vision problems context about their surroundings. The app is made to run in the background of the user’s mobile device and respond to media controls, but if you are navigating around with a cane, getting to media controls on a phone or even a headset might not be very convenient. ...

Butterfly IQ – Ultrasound Anywhere, Anytime

Ultrasound, also known as sonography, is a medical procedure which uses sound waves to get images from inside the body. It is used to help guide biopsies, diagnose causes of pain, examine a baby in pregnant women, diagnose heart conditions etc. High- frequency sound waves are transmitted to the body using a small transducer (probe), then the probe collects the sounds that bounce back, and a computer uses th ...

Arduino Sunflower – an Electronic Sundancer

Maker is always sensitive to the new and funny things. One day, I watched a video, in which the sunflower moves along with the sun. I had a sudden insight then. Why can't I make a electronic device inmitating this biomechanism. In the following days, I began to carry out my solar tracker project. I selected the crowtail as the microcontroller board, and picked up the componets and accessories in our warehou ...
