It monitors the electricity consumption and sends the detected data to the cloud through the GSM cellular network; it is based on an Arduino Mega equipped with GSM Shield and a board on which the measurement...

  It monitors electricity consumption and sends the detected data to the cloud through the GSM cellular network; it is based on an Arduino Mega equipped with GSM Shield and an absorption detector board. First instalment.  ...

  With Arduino Mega, we create, a keyboard with RFID module, a configurable access control system, to manage electric locks.   In the market there are different types of controls for electric locks: from the simple insertion...

With 10 million Arduino UNO sold worldwide, this board becomes the most widespread prototyping board ever. The first Arduino UNO board was introduced in 2005 and in those days integrating a communication system such as WiFi was...

The usual rectangular shaped PCBs got bored. The current prototyping services like PCBWAY allow to create PCBs with different shapes. An excellent software that allows you to get the gerber to be printed is Eagle. With the...

We emulate the TDG series remote controls using the GSM Shield. It’s not been long since we presented our GSM shield for GSM/GPRS modules SIMCom, QUECTEL, FIBOCOM etc. that was born to be incorporated in Arduino-based projects...

Motion detector based on the Doppler effect, made by combining a specific sensor with a circuit that amplifies the output signal. Now the devices used in presence and movement detection systems, to be combined with automations for...

It solves the problem of pitch loss that can trouble 3D printers and which, especially in large printers that require many hours to print parts, can mean huge losses of time and money. In previous posts we...

Let’s describe the firmware of the stepper motor feedback controller and test it on the 3D printer. (Read the first post) In the limits of non-retroactive stepper motor control is that in applications for the drive of...

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...

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...

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...

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...

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,...

  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...

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...

Rubik’s cubes have been mystifying and frustrating people for more than 40 years now. According to Forbes, 450 million Rubik’s cubes had been sold by 2020. But based on our very scientific estimates, only a small fraction...

As Peter Balch explains, COVID-19 can sometimes give rise to cardiac complications. So, while not presented as an actual piece of medical equipment, he decided to construct an ECG (electrocardiogram) unit using an Arduino Nano for control...
