Key Learning Points:
- Sensor input: Students learn how to process sensor data and convert it into meaningful actions.
- Motor control: The project introduces the concept of pulse width modulation (PWM) for smooth motor control.
- Conditional logic: Students implement if-else statements to navigate the robot along the path.
Extensions:
- Add a third IR sensor for better accuracy.
- Introduce a timer to measure how fast the robot can complete a course.
2. Create a Bluetooth-Controlled car

5. IoT-Based Home Security System
Project Overview: A home security system project challenges students to use the ESP32’s Wi-Fi and sensor capabilities to build a system that monitors doors, windows, or motion and sends alerts to a smartphone. This project combines hardware (e.g., motion sensors, cameras) and software (e.g., sending SMS alerts) to create a real-world solution.
Steps:
- Connect PIR motion sensors and door/window sensors to the ESP32.
- Write code to monitor sensor data and trigger alerts when motion is detected or a door/window is opened.
- Use IR communication to send messages between two boards.
Key Learning Points:
- Sensor integration: Students learn how to integrate multiple sensors into a single system and process their input.
- Cloud-based notifications: They gain hands-on experience with sending data from IoT devices to the cloud for monitoring and alert systems.
