An unusual one for me, I have not personally used Arduino tools in pursuing DevOps, but “Arduino Data Communications” (Packt, 2023) By Robert Thas John makes a good case. This tool could come in handy if you are working on edge deployments or integrating sensors into on-site tools. The book does a great job of going through the various options, constructing the boards, and using different telecommunication settings. Three sections appear: an introduction to Arduino, sending data, and miscellaneous topics. Recommended for those seeking communication solutions to software difficulties. The first section deals with Arduino’s unique approach to building the development environment into the hardware board. This results in needing the physical connections for sensors and other tools. The section discusses using shields and carriers, external devices, and linking those connections to the Arduino tools to integrate data. It also discusses the challenges in storing data externally, the board does not hold the data, and the connections to various APIs and REST formats to enable the external board to succeed. Various data formats are included, from heat and humidity to motion and acoustic inputs. Connecting to sensors follows up in the second section with connections to various communication tools. Included are basic types of short, medium and long-range options before delving into some specific applications. First up in specifics is LoRaWAN, a Low-Power, Wide Area Network (LPWAN) protocol and its connections to The Things Network TTN. The TTN provides some easy and approved solutions and a way to register devices. The other transport devices are cellular comms, the HC-12, and the RS-485. Connections also discuss ethernet linkages; each section includes labs to test your skills. The final section discusses some strategic options for incorporating Arduino into your overall plan. These include security solutions, scaling for high availability, and building hardware. While all the tips were good, there was not a high lot different from any other type of solution. Security fixes included items like encryption and identity management while the scaling discussed power and network outages, hardware failures, and load-balancing across multiple boards. The building chapter does touch on using 3D printers to produce boards but unfortunately, no schematics were provided. If I had one complaint, it would be that I do not have a lot of experience in this area. I’ve done some work with microcontrollers, and wiring boards but not enough to push me into an Arduino type solution. Even when using edge devices, most of the connections are still either a direct visit to the site with a hard drive, or a encrypted Wifi type solution. If I was moving to Arduino, this book certainly offers enough tips for me to get started.Overall, “Arduino Data Communications” By Robert Thas John was a good read. Not quite all the way in my wheelhouse but with enough overlap that I can certainly see benefits. If the solutions you seek are more sensor and edge based, this is probably a good add. Also, if you enjoy working with hardware, and building your own boards, I’d pick this one up.

"Arduino Data Communications" is a valuable resource for anyone interested in learning how to use Arduino for data communications. The book is well-written and easy to understand, even for beginners, and provides a wealth of information on the subject.I highly recommend it to anyone looking to expand their knowledge of Arduino, IoT and data communications.
