Javascript all the things
0 likes•1,203 views
The document outlines a talk on JavaScript and its applications in the Internet of Things (IoT), featuring various hardware platforms like Arduino, Raspberry Pi, and devices such as Google Glass and Oculus Rift. It emphasizes JavaScript's ease of use for building applications that connect the physical world to the web, supported by libraries like Johnny Five and Noduino. The author also discusses potential business applications and future implications of integrating sensors and interactivity into everyday objects.
