A simple AVR microcontroller based circuit that can detect when you touch a metal probe connected to one of the mcu inputs. A simple AVR microcontroller based circuit that can detect when you touch a ...

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 ...

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 ...

Speech synthesis has been around since roughly the middle of the 20th century. Once upon a time, it took remarkably advanced ...

We created a comprehensive ESP32 CAM Telegram bot tutorial that can capture images and record custom-duration AVI videos, which can be stored locally and sent to Telegram for viewing. As you might ...

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 ...

How do you tell how much load is on a CPU? On a desktop or laptop, the OS usually has some kind of gadget to display the basics. On a microcontroller, though, you’ll have to roll your own CPU load ...

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 ...

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 ...
