Controller with stepper motor feedback able to dynamically check the shaft positioning and prevent possible step losses. Who has never happened to launch a complex and long 3D print, maybe a job of hours or dozens of hours, to be absent and discover that, when the job was almost finished, the printer engines lost a…
Innovation and the general public in contact again! Thanks to the constant progress of the vaccination campaign, “Maker Faire Rome – The European Edition“, the biggest European event dedicated to innovation, promoted and organised by the Chamber of Commerce of Rome, is back on time again this year, but with the great novelty of reopening…
We create the instrument that the reports have brought in vogue, but that for years has been used in hospitals and in sports medicine to verify the degree of oxygenation of the blood. The Coronavirus epidemic that we have experienced, and in a certain sense are still experiencing, has put on everyone’s lips terms such…
8 relays controlled by 8 opto-isolated digital lines or by Raspberry Pi. It’s not the first time that we propose a relay board, because in these pages you have found both generic control boards that can be driven with voltage levels and logic states, and specific boards for use with Arduino. Still, surely the project…
Getting to know and evaluate the software offer for PCB, in order to choose the best one for our needs. Designing an electronic board is a considerable and varied effort, both in terms of board design, starting from its functional specs, and in terms of construction. In order to create an integrated board, we…
It automatically supplies meals to your pet at preset times, by providing the daily dose of cat kibble. Having a pet involves big responsibilities, first of all granting them food; unfortunately, a hectic lifestyle and imposed workhours do not go hand-in-hand with the needs of our four-legged friends, and surely anyone living on their…
Identify faces in a video or live shot and recognize if they are wearing a mask: easy with the “raspberry”. The spread of COVID-19 has created a global health crisis that has had a profound impact on humanity, the way we perceive our spaces and our daily lives. As of December 2019, we have witnessed…
In this post we are going to learn how to build a RFID based attendance system using Arduino development board, RC522 RFID reader module and external EEPROM. We will take a brief look at RC522 RFID module, external EEPROM and other circuit modules that makes this proposed RFID attendance system work. RFID card based…
In this project, we’ll create a status indicator PCB shield for the ESP32 featuring two rows of addressable RGB neopixel LEDs, a BME280 sensor, and a pushbutton. We’ll program the board to display a web server with the BME280 sensor readings and show the temperature and humidity range on the LEDs (like two progress…
Connected to the USB port of a computer, it allows you to simultaneously control four dual-channel infrared receivers of the POWER FUNCTIONS LEGO® series through simple serial commands. A few years ago LEGO®, manufacturer of the most famous brick in the world, introduced a system to make the most important sets dynamic through a very…
In this project we’ll create a PCB shield for the ESP32-CAM AI-Thinker board with a PIR motion sensor, a BME280 temperature, humidity and pressure sensor and some additional exposed pins. We’ll create a Telegram bot for the ESP32-CAM that allows you to control your board from anywhere to request a photo, sensor readings or…
Hey Geeks, Now I am studying in +2 which is equivalent to 12th Grade. I am very interested in computer science and also my main subject is that. I spent a lot of time in developing Embedded projects. I have around 3 years of experience in the embedded field. I always focus on innovative…
