This document discusses the rise of DIY and maker culture through the growth of makerspaces and the increasing accessibility of hardware like Arduino and Raspberry Pi. It also explores how this relates to the expanding Internet of Things through the use of sensors, actuators, and connectivity to build interactive devices and systems that can be used for health monitoring, home automation, environmental monitoring, and more. Open source platforms and cloud services are enabling more people to get involved in developing IoT applications and building the "physical web".
