The author described briefly about the challenges involved in combining a light sensor with a LED.Like we know that combining a mic and a loud speaker in a audio system will bring a big howling sound due to acoustic feed back. Many techniques are adopted to reduce the same or totally to remove it. Similarly combining a light sensor with a LED also will produce a lot of light feed back.
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.
