Progress:

This week, we made a big step forward by modifying our code to allow temperature-based fan speed control! Now, the fan dynamically adjusts its speed depending on changes in room temperature, bringing us closer to a fully adaptive cooling system.

Challenges

Kickstart Issue Persists – The DC motor still struggles with mechanical friction, requiring an initial push to start spinning. We may need to fine-tune the power input further or consider alternative motor solutions.

Slow Sensor Response – The temperature sensor takes time to register changes, making it harder to see real-time adjustments in fan speed. We might explore ways to smooth or predict sensor readings for better responsiveness.

Next Steps

1. Implement the Servo Motor – Integrate the servo to control the fan’s oscillation for directed airflow.
2. Refine Fan Speed Adjustments – Optimize the response time and reliability of temperature-based speed changes.
