This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

In the modern electronics industry, devices are becoming smaller, faster, and more sophisticated than ever before. To meet ...

The advent of microcontroller modules like the Arduino opened up ability to build and program interactive objects to a whole generation of makers. Today these modules make it simple to control ...

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 title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

Deep in the heart of your latest project lies a little silicon brain. Much like the brain inside your own bone-plated noggin, your microcontroller needs protection from the outside world from time to ...

Researchers at Georgia Tech have developed a new technique to print advanced, ink-based electrical circuitry on a desktop printer. Using about US$300 worth of off-the-shelf equipment, the researchers ...

Though it’s no huge shock to find out what’s behind Esquire’s recent E-Ink cover, it’s always fun to look at the postmortem pics. Phil over at MAKE took the magazine cover apart, and in addition to ...
