Lab 02: Line Following Robot Closed Loop Control

🚀 Coming Soon! This product is not yet available for purchase. Stay tuned for the launch!

Lab 02: Line following Robot "Closed Loop Control" is the second project in the Line Following Robot. 

This project presents the design and implementation of an enhanced smoke detection system using an Arduino Uno microcontroller. The system integrates multiple sensors, including a gas sensor to detect harmful gases (smoke) and a Passive Infrared (PIR) sensor to detect human presence. Then every time the smoke is detected, the system signal buzzer to alert sound alarm immediately. Additionally, two LEDs were used to visualize real-time situation which red is for emergency, while blue is for human's present.
