Emulating older computers on microcontrollers has been a staple of retrocomputing for many years now, with most 8-bit and some 16-bit machines available on Atmel, ARM, or ESP32 platforms. But ...

I built a card reader interfaced with a LCD and Microcontroller. It displays the name of the person on the LCD to confirm identity when a card is inserted. It’s a simple prototype of card identifiers ...

Integrating processors, sensors, and data exchange functionality into everyday objects, the Internet of Things (IoT) pushes computing capabilities far beyond desktops and servers, weaving computation ...

Raspberry Pi has introduced a successor to last year’s Pico, a $4 microcontroller based on the RP2040 chip the company designed itself. The new model is called the Pico W. It’s basically the same ...

Where code meets reality, embedded systems come at that intersection, demanding precision, efficiency, and careful planning.

The device is almost similar to typical electrical key-locks but with the use of only one input of microcontroller to read more keys. In the design, an analog to digital converter is to detect ...

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 ...

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 ...

The Raspberry Pi Pico 2 is an upgraded version of the original Pico microcontroller, featuring enhanced performance, increased memory, improved power efficiency, and new security features. It retains ...

When designing a system, one of the most important design decisions is choosing what voltage domain(s) to use. Some voltage domains, such as 5 V, are good for noisy and harsh operating environments ...
