One of the first projects that most people do on an Arduino is to light up or flash an LED. It seems ultra-simple because it ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

The Arduino has long been a staple of the maker community. Longer than 3D printing has been as popular as it is, in fact. So, ...

Many small microcontrollers require so little power that often they can draw what they need through their loads. This can simplify a system, reduce its cost, increase its reliability, and provide ...

[Marius Taciuc’s] latest endeavor, the B4 Thinker, offers a captivating glimpse into microcontroller architecture through a modular approach. This proof-of-concept project is meticulously documented, ...

What just happened? Raspberry Pi has just released a new module designed to simplify the development of turnkey wireless hardware solutions. While the single-board computer company has long offered ...

In its introductory blog post, the company explains that today’s Raspberry Pis are already often used alongside a smaller microcontroller: The Raspberry Pi takes care of heavyweight computation, ...

Using a PN-junction diode for temperature measurement usually depends on its 2‑mV/K temperature coefficient. Conventionally, you must amplify and digitize this voltage with an ADC before you can use ...

There are several ways to convert an AC voltage at a wall receptacle into the DC voltage required by a microcontroller. Traditionally, this has been done with a transformer and rectifier. However, in ...

In safety-critical applications, trouble-free operation is enormously important, especially for microcontrollers. By law or in companies from the automotive, health or production industry, there are ...
