If you ever wanted to integrate touch sensitivity into your project, this board could just do the trick. It’s a capacitive touch sensor. These sensors are used in our everyday consumer electronics like notebook trackpads, video game consoles, touchscreens…just to name a few. They work on the principle of alteration of the electrostatic field. The […]

It can be a herculean task to get kids to eat their vegetables, but they’ll happily chow down on things they aren’t supposed to. If one of those things is a button battery, serious injuries can result in the form of burns to the esophagus or tears in the digestive tract. Researchers may not have […]

Introduction EasyEDA is a free web-based electronic circuit design tool. It’s one stop design shop for your electronics projects, which offers schematic capture, spice simulation, PCB design and PCB order service. EasyEDA is designed to give electrical engineers, educators, engineering students and electronics hobbyists an Easier EDA Experience. More introduction about EasyEDA, you could check […]

The Company AMS AG has introduced the non-contact AS5601 Hall-based rotary magnetic position encoding chip. It works by sensing changes in the magnetic field components perpendicular to the surface of the chip and converts field changes into voltages to produce incremental A/B outputs and absolute position information that can be read over an I²C bus. […]

The USB Specification Evolves Other than generous helpings of coffee, what helps industry decrease time to market, drive down cost, and focus more of the design cycle on innovation? Hint: standardization. By defining protocols and operating characteristics, standards have impacted all aspects of technology: device package sizes, pin outs, data and communication interfaces, software drivers, […]

In this guide I will explain how to use a Windows 8.1 phone, Arduino Uno board, and HC-05 Bluetooth module to build a wireless oscilloscope. The phone application has the critical functions of an oscilloscope, although the bandwidth is a measly 300 Hz. Still, if you want to see squiggly lines on your phone, it […]

A multidisciplinary engineering team at the University of California, San Diego developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in […]

Bigger and Better Projects Once you have mastered the basic blinking leds, simple sensors and sweeping servos, it’s time to move on to bigger and better projects.  That usually involves combining bits and pieces of simpler sketches and trying to make them work together.  The first thing you will discover is that some of those […]

This Lazy Old Geek (L.O.G.) loves Arduinos. I have noticed that a lot of sensors, like GPS, LCDs, magnetometers are 3.3Vdc sensors. But the standard Arduinos, Uno, RBBB are 5Vdc modules. So I decided I’m going to make more of my Arduino projects with 3.3Vdc AtMega328s. Now I’ve done this before but will go through […]

Do you have a habit of leaving notes on the fridge, now take it digital and add an Arduino to it. In this instructable I’m going to show you how to do just that. All you need is an Arduino, an LCD screen and a Bluetooth module to make this and a Android mobile to […]
