The PIC16F15386 family, the most powerful launching point into the 8-bit PIC microcontroller portfolio, is now available from Microchip Technology. In addition to our current Core Independent Peripherals, this family includes a high-accuracy 32 MHz internal oscillator and memory features...

The tiny Pixel 2.0 is basically an Arduino board wedded to a tiny 1.5″ 128×128 color OLED screen. This means you can stick it inside a wearable and address the screen directly from the Arduino board, an improvement on current “solder the screen to the Arduino and hope it works” world of DIY electronics. This teeny-weeny board costs $75 on Kickstarter and should ship in June...

Seiko Epson Corporation has begun shipping samples of the S7C17M11, a low-power 16-bit microcontroller with on-chip Flash memory, a crystal unit, and a highly accurate real-time clock...

A good, reliable and easy to use dc power supply is probably the most important thing for every electronics hobbyists. Since a proper electronically stabilized power supply is crucial for almost all microcontroller-related diy projects, here we are presenting a simple diy project of an easy to build and very affordable power supply for microcontrollers...

It’s been a long wait, but our latest single board computer for review is finally here! The BBC micro:bit, given free to every seventh-grade British child, has landed at Hackaday courtesy of a friend in the world of education. It’s been a year of false starts and delays for the project, but schools started receiving shipments just before the Easter holidays, pupils should begin lessons with them any time now, and you might even be able to buy one for yourself by the time this article goes to press...

Many Design Ideas have shown how to use the Charlieplexing technique to drive as many LEDs as possible with a minimum number of I/O lines. This Design Idea shows how you can drive three LEDs and scan three switches with only three I/O lines instead of six...

Leonie and her family live in a building with seven other families. Like many cats, Leonie loves to explore her surroundings, and after satisfying her curiosity, she likes to return home, where it’s warm and dry and there’s food... Usually, she just needs to wait in front of the building entrance, where somebody will open the door for her and she can get to the inside staircase. Entering her apartment, however, is more difficult...

Two new microcontroller lines from STMicroelectronics increase energy efficiency, flexibility, and feature integration at the high end of the STM32F4 Access Line for high-performance embedded designs. Qualified up to 125 °C, these latest STM32 devices target always-on sensor acquisition and general-purpose industrial applications, and present a robust and cost-effective upgrade from STM32F1 MCUs...

GainSpan Corporation announces a new Starter Kit Board utilizing the GS2200MIZ Wi-Fi mini module that is the smallest module in its class – as small as a penny – while still providing high performance, industry-leading application resources and battery life. The GS2200M Starter Kit Board is an easy to use evaluation and development platform for GS2200Mxx-based designs. It is equipped with Arduino...

The new PIC24 “GA7” family of microcontrollers is now available from Microchip Technology. As the lowest-cost 256 KB Flash memory 16-bit MCUs available today, these PIC24 devices enable extremely cost-effective designs for Internet of Things sensor nodes, portable medical devices and industrial control applications...
