Internet of Things (IoT) — Grades 11-12

This course introduces students to the Internet of Things (IoT), a transformative technology shaping modern life. Through hands-on projects, students learn how to connect sensors and actuators to microcontrollers like the ESP32, collect and process data, and build real-world smart systems.

The course emphasises collaboration, critical thinking, and creative problem-solving while integrating coding, electronics, and mobile app control using Blynk. Students complete individual and team-based projects, culminating in a final product showcase.

Key understandings

• IoT connects physical devices to the internet, enabling smart data-driven systems
• Sensors collect data from the environment; actuators perform actions based on decisions
• Microcontrollers like the ESP32 are the brains of IoT systems
• Wireless control and cloud connectivity are key components of modern IoT
• Real-world problems can be solved through creative design and programming of smart systems
• Collaboration, iterative design, and testing are essential in engineering smart technology
