What is an operational amplifier? The operational amplifier (also called opamp) is a solid-state analog electronic component capable, as its name suggests, of amplifying an electrical signal. It is defined as operational because it is able to perform some mathematical operations in a totally analogical way on electrical signals. The generally possible operations are addition, […]
Creating the project using PlatformIO Today we want to see how to create a new project for the NodeMCU ESP8266 board using the PlatformIO IDE and how to add external libraries to the project. Please note that the operating system I use is a Linux distribution (specifically Fedora 36). So the folder structure in the

Introduction What is a digital potentiometer? We’ve all used a classic potentiometer at least once in our lives: it’s the classic volume knob on our radio! We may not even notice it when instead we are dealing with a digital potentiometer. When on the radio, to vary the volume of the music, we don’t use

What is the thermo-hygrometer used for? A thermo-hygrometer is a device that measures ambient temperature and humidity. These two parameters are measured by a special sensor at regular time intervals. They can then simply be viewed on a display or stored on an SD card (in order to have a history) or even sent to

Introduction In this tutorial we will see how to make an ultrasonic distance meter. Ultrasounds are acoustic waves having a frequency higher than that audible by humans. The medium crossed by the ultrasounds conditions its propagation speed. They are slower in gaseous media and faster in solid media. In air the speed of propagation is

Introduction In this tutorial we will see how to solder a 16-pin connector on a 1602A LCD display. You can see all the projects featured in this blog using this display by going to the link https://www.techrm.com/tag/1602a/.
Introduction This is a simple guide that will teach you how to take the first steps with the BTE13-010 module, a cheap Arduino mini clone. We will go through the 4 basic steps necessary to get it working immediately and without problems: * Not strictly necessary but very useful if you are planning to use
