Temperature Sensing and Display using SPI Communication with ATMEGA 328P

This paper presents a simple and cost-effective temperature sensing and display system using SPI communication. The main components used are the LM35 temperature sensor, ATmega328P microcontroller, and a 1dx2 LCD for display. The system reads analog temperature data from the sensor, converts it using the ADC (Analog to Digital Converter), and sends the information using SPI protocol. The temperature value is displayed in real-time on the LCD screen. This project demonstrates how SPI communication can be used effectively in small embedded systems for real-time applications, making it suitable for temperature monitoring in various fields like home automation and industry.
