Conclusion
In this project, we successfully implemented a system that reads temperature data from a TMP36 sensor, displays it on an LCD1602 display, and uses a buzzer to alert when the temperature increases or decreases. This project combines several fundamental components and techniques in electronics and programming, demonstrating how microcontrollers can be used to create practical and interactive systems.
By combining these components, we created a system that not only monitors temperature but also provides real-time feedback and alerts, making it a practical solution for various applications. This project showcases the importance of integrating multiple technologies to build comprehensive and effective monitoring systems.
