I recently got the change to give a ThingSpeak IoT demo at Boston TechJam. MathWorks is one of the sponsors so we got to participate with other tech companies and over 8,000 students and entrepreneurs from Boston. My demo used MATLAB to detect multiple faces from a live stream of video. The MATLAB analysis code sends the count to a ThingSpeak channel. I used the new ThingSpeak gauge widget to show how many people stopped and participated in the demo.
