You should create a 3D version. Then you can use the software from your Arduino LED cube. Shouldn't any software person be able to read the code and instinctively know where to go. Right?
As for me, I took a line dancing class once. The carnage was legendary. I turned the wrong way so many times and ran people over so many times that the instructor had to call in the National Guard to get me out and bandage up all of the kicked ankles. I think I'm banned for life from ever again attempting anything that requires actual physical coordination.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
