Free Elektor Article: Using E-paper with the Arduino
https://www.electronics-lab.com/free-elektor-article-using-e-paper-arduino/
Electronic paper — a.k.a. e-paper — is an unusual type of display. Once a picture (or text) is displayed, no further energy is required to maintain the display. Energy is only required to change the display. This is very useful in applications where the amount of available energy is limited. In this article we describe […]
Kryptor FPGA: Open-source hardware end-to-end encryption
https://www.electronics-lab.com/kryptor-fpga-open-source-hardware-end-end-encryption/
Data security and privacy are becoming more of a necessary requirement for the Internet of Things (IoT), and other communication-based solutions. This is because for these solutions to become ubiquitous in homes, businesses, and agencies around the world, they have to be immune to data theft or even bad actors who try to cause system […]

https://www.electronics-lab.com/meet-sparkfuns-qwiic-pro-micro-usb-type-c/
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 refresh, a Qwiic connector at the back […]
Arduino Pro IDE
https://www.electronics-lab.com/arduino-pro-ide/
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 it unusable for professional embedded software developers. […]
Introduction to LoRa – Send data between two Arduino using LoRa
https://www.electronics-lab.com/introduction-lora-send-data-two-arduino-using-lora/
Selecting the right communication protocol is an important part of any IoT project as not being able to communicate with the server/device cloud quickly takes away the “I” in IoT and could lead to the ultimate failure of the project. Several communication protocols exist, from WiFi and Zigbee to 2G, LTE, and even satellite communications, […]
