Signetics released the venerable NE555 timer in 1971. It has been used in thousands of designs and has been the subject of at least that many articles (see “The 555: Best IC Ever Or Obsolete ...

As computer systems become more and more ubiquitous in everyday items, the workings of those items will require some sort of digital controlling. Controllers that once handled large mechanical systems ...

Microcontrollers are taking on a variety of new and much more complex computing tasks, evolving from standalone chips to more highly integrated devices that can rival complex microprocessors.

The first program anyone writes for a microcontroller is the blinking LED which involves toggling a general-purpose input/output (GPIO) on and off. Consequently, the same GPIO can be used to read ...

A solid knowledge of logic gates is at the basis of programming and electronics. This is required in any project. Truth tables are a great way to visualize the results of various combinations of ...

Meet the Raspberry Pi Pico 2 W, a tiny board designed around a microcontroller that lets you build hardware projects at scale. Raspberry Pi is once again using the RP2350, its own well-documented ...

We’ve spent a fair amount of space talking about adding A/D converters with higher speeds and more precision. There are applications that merit higher capability. But most makers already have a “free” ...

My Lab Bench has been piling up with stuff to check out, and I needed to clear some space for new stuff. The latest crop includes an economical, compact logic analyzer, a new version of my favorite ...
