Flow rate and volume helps tell the amount of fluid going into, or through a particular vessel. For certain process automation applications, this simple-sounding fluid measurement task is so critical to the success of the project that, failure to get it right, could bring the entire...

David Johnson-Davies published a new project on his personal blog. He shows us how to build a minimal microcontroller on a breadboard based on the ATmega4809, the microprocessor used in the latest AVR-based Arduino boards. It includes a USB-to-serial converter so you can connect it to...

Angelu (Elsofgel), a Canadian-based electrical engineer has developed an Arduino shield to implement an SPI to Ethernet Interface (SEI) on the PIC32 microcontroller. While it seems very similar to the Wiznet’s chips, the major difference being that it is a software implementation and...

One of the best things about being a maker is the ability to make your own tools. We have covered the development of several electronics tools in past, from voltmeters to battery testers. For today’s tutorial, we will add another tool to the list by examining the development of a...

The saying that “everything old is actually new again” finally became a reality for the Pro Micro board, as the popular Arduino compatible board gets revised with few additional features. The board that has been a favorite for about half a decade now received something of a great...

This smart device is able to monitor and display CO2, TVOC, PM, temperature, humidity and air pressure measurements. by Roman Novosad Most of the modern applications focus on measuring outdoor air pollution. This is indeed very important and useful, however most of the time in...

I’m a big fan of the ESP32 boards because of the number of communication options they managed to squeeze on the board, but I became more impressed recently when I came across the TTGO LoRa32 development boards which adds LoRa to the onboard communication features of the ESP32. The...

From its lack of simple things like code IntelliSense to more complex requirements like a debugger, quite a number of articles and comments have been written in the past about the inadequacies of the Arduino IDE. Many have pointed out how the IDEs’ attempt at simplifying things makes...
