Construction of a Comprehensive Experimental Platform for the Internet of Things Based on PDA—An Integrated Experimental Design from Principle (P), Design (D) to Application (A)

In response to the challenges of low integration, poor scalability of experimental platforms, and a lack of diverse content in the experimental teaching of the Internet of Things, a comprehensive IoT experimental platform and teaching scheme based on the PDA experimental board is proposed. The construction process of the hardware and software for the comprehensive IoT platform is introduced, the experimental tasks and implementation procedures are detailed, and the project outcomes are presented. The platform features clear and intuitive operations, and rich content, integrating theoretical knowledge with practical exercises, thereby facilitating students’engagement in scientific research and practical training.
