Quick-reference (QR) codes are similar to barcodes, as they are able to encode data that is represented by black and white squares. But instead of using a laser, a camera differentiates between the spaces and then sends that information to be processed. They are comprised of several large squares that help to align and position…
To keep a eye on the current Corona-Virus numbers I created this Programm wich displays the current stats to the Display. More info
https://youtu.be/Hfab9JSf1BA Just to make it very clear, this project is meant to provide some comic relief during these times, it’s not meant to disregard the severity of the current situation.

In this project, I wanted to create a surveillance video camera for my library, especially for one particular bookcase, to get notified when someone takes a book or organizes books differently. In that regard, I programmed a Raspberry Pi 3 Model B+ to capture the first-look thumbnail image and record a video with timestamp according…
A device that makes Raspberry Pi suitable for industrial environments, an alternative to PLCs for automation control applications. In the 206th issue of Elettronica In, we featured the first device in the Strato Pi line created by Sfera Labs: the Strato Pi Server. This product, designed for industrial environments and based on Raspberry…
Let’s see how to use this shield along with Raspberry Pi, by means of a dedicated library. In the last installment we gave readers description of a new RTCC shield, based on the MCP79410 integrated circuit, by Microchip just after having presented the sketch for Arduino; now, as anticipated in the first installment,…
Let’s use a new Real Time Clock by Microchip, by making it available on a shield for two prototyping boards. First Installment. Many applications require an hourly information, that is locally obtained by means of circuits that are named RTCs (Real Time Clock) or RTCCs (Real Time Clock Calendar); among them are clock…
What the heck is an IoT computer? It is a Linux computer designed specifically for building connected hardware applications. It combines the tiny form factor and power-efficiency of the Arduino, with the power and flexibilities of the Raspberry Pi. The Omega2 is simple, even for people who are just getting started with building hardware. The…
