What to do when the chosen microcontroller doesn’t have enough pins? We will find out in this tutorial, where we will learn how to use shift registers to control LEDs and read buttons with just three wires! In six steps, we will use the CD4094 and CD4021 with a PIC microcontroller.
The low cost of sensors and components allows us to build small gadgets and tools that were unthinkable just a few years ago. In this project, a “bubble” level has been created, which is a tool used to determine if a surface is perfectly level. The level was constructed using an accelerometer and an…
ChatGPT is an artificial intelligence-based chatbot that was introduced by OpenAI on November 30th. With ChatGPT, it is possible to engage in conversations and discussions. In fact, GPT stands for Generative Pretrained Transformer, and it is programmed to be able to converse with the public. Various voice assistants also operate on this basis. We tested…
Connect our ESP32 Demoboard to Arduino IoT Cloud to remotely monitor and control sensors via a web dashboard. In this free webinar, Fabrizio Mirabito (IoT Cloud Manager at Arduino) will demonstrate how to connect the ESP32 to the cloud, enabling remote monitoring and control of sensors and actuators through a web dashboard. For this purpose,…
The initiative rewards the most innovative projects in areas related to environmental sustainability. FAE Technology will manufacture the electronic board prototypes for the top three winners. The contest is organized in collaboration with FAE Technology S.p.A. an Innovative SME operating in the design, prototyping, engineering, and production of integrated electronic solutions, announces the launch of…
Stereo power amplifier 10+10W into 8 ohms based on the integrated PAM8610, suitable for systems that require high efficiency and little heat to be dissipated. By now, the miniaturization of electronic circuits is advancing unstoppably. It involves even those devices of traditional electronics such as audio amplifiers, which do not have a strict…
Based on a single chip from Terminus, it allows you to connect four USB devices starting from a micro USB port; the form-factor is designed for pairing with Raspberry Pi Zero. We all know what a USB hub is, since at least once we all had to deal with it at home or…
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 to produce the final product. The printed object can have any shape and geometric characteristics, making it a…
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 a very topical problem, especially in large urban agglomerations and near the large industrial areas bordering large cities….
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 crystal, it is difficult to imagine how text and numbers were displayed before their advent; Well, those who…
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 using ecosystems related to prototyping boards such as Arduino has proved to be very effective; next to it…
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 can control any electrical appliance with the help of Google Assistant. More info
