Unlike the standard ESP32 microcontroller, the CAM variant includes a camera module and a microSD card slot built into it.

Simple Sound Processor presented here is an ultra-simple circuit module suitable for almost all basic electronics and microcontroller projects. For example, this module can be used as a front-end in ...

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 ...

Recently, I wanted to build a Sleepy-LED Eye as an add-on indicator for a small personal project. My idea is a near-replica of the iconic breathing pattern used for the “sleep” indicator in Apple ...

We’ve got a thing for projects that have no real practical value but instead seek to answer a simple yet fundamental question: I wonder if I can do that? This dead-bug style 555 blinky light is one of ...

This hack shows how to make a dumb terminal out of a keyboard, LCD screen, and an 8-bit microcontroller. From time to time, a portable dumb terminal can be handy for when you have to rescue a headless ...

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, ...

Data security is very important in data transmission. There are many methods to make the data to be secure. One of the methods is by using cryptography algorithm to encrypt the data. Using the ...
