Project Name: Ultrasonic Distance Alert with Visual & Audio Indication using AT89S52 (8051)

Hardware Components:
• AT89S52 Microcontroller on 8051 Dev Board
• HC-SR04 Ultrasonic Sensor
• I2C 16x2 LCD Display
• MAX7219 8x8 LED Matrix
• Buzzer & 3 Status LEDs
• Arduino Mega (for use as ISP Programmer)
• Keil uVision + AVRDUDE Setup

Project Overview
This project shows how to measure distance with an ultrasonic sensor and display the result visually through an I2C-based LCD and an 8x8 LED matrix. The data is processed by the 8051 microcontroller, a buzzer and LEDs are controlled depending on the proximity, and an emoji pattern is updated in real time to indicate object distance. Great for proximity alerts, obstacle detection, and learning embedded systems!

Functionality Highlights:
✔️ Real-time distance measurement using HC-SR04
✔️ Buzzer and LED alert for near objects
✔️ Dynamic emoji representation of object distance
✔️ LCD output using bit-banged I2C protocol
✔️ Embedded C code using Keil IDE

Flashing Tools:
• Arduino Mega as In-System Programmer
• AVRDUDE to burn.hex file
• Keil to develop and compile code
