Welcome to IoT Central: The online community celebrating practitioners at the intersection of traditional embedded systems and the Internet of Things.

 

As small as a postage stamp, the Seeeduino XIAO boasts a 32-bit Arm Cortex-M0+ processor running at 48 MHz with 256 KB of flash memory and 32 KB of SRAM.

A couple of months ago, I penned a column, The Worm Turns, in which I revealed that — although I’d been bravely fighting my urges — my will had crumbled and I had decided to create a display comprising a 12 x 12 = 144 array of ping pong balls, each illuminated with a tricolor WS2818 LED (a.k.a. a…

It’s been a long time since I performed Karnaugh map minimizations by hand. As a result, on my first pass, I missed a couple of obvious optimizations.

I’m sorry about the title of this blog, but I’m feeling a little wackadoodle at the moment. I think the problem is that I’m giddy with excitement at the thought of the forthcoming Thanksgiving holiday. …

The "internet of things" will provide cyber criminals with new ways to exploit faults in personal security systems.

As the number of online devices surges and superfast 5G connections roll out, record numbers of companies are offering handsome rewards to ethical hackers who successfully attack their cybersecurity systems.

The fast-expanding field of internet-connected devices, known as the "nternet of things" (IoT) which includes smart…

Arduino Mega footprint; three 32-bit cores all running at 200 MHz; 4 Mbytes of Flash and 500 Kbytes of RAM; works with the Arduino IDE; what’s not to love?

I tend to have a lot of hobby projects on the go at any particular time. Occasionally, I even manage to finish one. More rarely, one actually works.…

The COVID phenomenon has upended businesses in several verticals, and among the most impacted is the foodservice industry, characterized by high-touch, labor-intensive and, mostly indoor operations. However, this industry has taken the initiative to adopt modern technology to fight its way out of the crisis.

Case in point - a major US foodservice company with nearly $10B in revenue and over 1000 stores nationwide recently made the decision to partner with Ayla Networks as part of its…

by Ulsan National Institute of Science and Technology

A tiny microsupercapacitor (MSC) that is as small as the width of a person's fingerprint and can be integrated directly with an electronic chip has been developed. This has attracted major attention as a novel technology to lead the era of Internet of Things (IoT) since it can be driven…

In order to form proper networks to share data, the Internet of Things (IoT) needs reliable communications and connectivity. Because of popular demand, there’s a wide range of connectivity technologies that operators, as well as developers, can opt for.

IoT Connectivity Groups

The IoT connectivity technologies are currently divided into two groups. The first one is cellular-based, and the second one is unlicensed LPWAN. The first group is based around a…

Arm DevSummit 2020 debuted this week (October 6 – 8) as an online virtual conference focused on engineers and providing them with insights into the Arm ecosystem. The summit lasted three days over which Arm painted an interesting technology story about the current and future state of computing and where developers fit within that story. I’ve been attending Arm Techcon for more than half a decade now (which has become Arm DevSummit) and as I perused content, there were several take-a-ways I…
