I recall a free tool that allowed you to model physical systems -- like putting rocks in the air and setting up a see-saw balance beam and suchlink, then pressing "go" and simulating what woudl happen -- I know this isn't an ee-related tool, but I wish I could find it again.
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.
