3D printing is a cutting-edge technology that enables the creation of three-dimensional objects through a layer-by-layer process. This method of printing starts from a digital model file and uses bondable materials such as metal or plastic powders...

Measure the quality of the air around us using a laser technology sensor that can quantify the concentration of the infamous micro-dust. Air pollution, and in particular the presence, quantification and concentration of so-called ‘fine dust’, is...

We pick up the fascinating Nixie tubes through displays based on packages of laser-engraved plexiglass plates, illuminated by Neopixel LEDs. For those born in the era of solid-state displays, be they LED, 7-segment, dot-matrix, or even liquid...

  Let’s learn about an interesting educational platform that allows you to make and study a real multitude of electronic circuits and their applications. Among the techniques to approach students and very young people, the one of...

  Imagine having all your devices connected via one smart voice assistant giving you the ability to turn things on or off as you wish. Well, you can do exactly that. Read on to see how you...

Water softeners work using a process called ion exchange in which calcium and magnesium ions from hard water are exchanged with sodium chloride (salt) via a special resin. The water goes into a pressure vessel where it...

  I wanted to please a friend, an environmentally conscious friend who is concerned about mould spores in the air (from damp), additionally he is an occasional smoker and lives on a fairly popular city road, so...

Hello everyone, This is a simple yet great and super easy project. In this project, we are using one ultrasonic sensor to track one object in one dimension, and finding it’s distance. Through this project, we can...

  This project consists of an interface window where we can control up to 8 dimmable lamps and create any effect with them without having to reprogram the Arduino. This can be useful, for example, to create...

Phone app to monitor and control vitals of fish in a home aquarium via ESP32. As you saw in the YouTube video, a mobile app connected to the internet has access to monitor and control the aquarium....

  The idea of this project has been on my mind for a while. The question of what if we can use our environment as a technology canvas motivates me to start experiment with this project. Luckily...

  Hello, all! This time, I will teach you how to write programs in the Arduino Web Editor. More info

  We develop and test applications with the Pro midi 1284P board.   Recently we have introduced and described a new prototyping board called PRO midi 1284, based on an ATmega 1284P microcontroller; after this presentation, made...

  It is halfway between an Arduino Mini (in size) and an Arduino Mega in terms of computational capacity, available memory and integrated peripherals. Since the creation of the Arduino project and the subsequent spread of the...

  Equipped with an SD card and RTC, it detects and stores temperature, humidity and barometric pressure using a combined sensor, showing the data graphically on a touch display.   Nowadays, also and above all in environmental...

  Lots of components to make applications that can be programmed with Arduino and assembled like LEGO bricks.   How many times did you dream of building something with LEGO bricks when you were a child and...

For all electronic designers, having new ideas and sources of inspiration is essential. At the base of the open-source movement there is the sharing of one’s own projects so that other technicians can take inspiration. There are...

  Let’s interface our Energy Meter with Internet to bring measurements to the ThingSpeak platform and see the results in convenient graphs.   A few posts ago, we introduced the MCP39F511 integrated circuit, capable of performing electrical...
