Report on Ultrasonic Sensor and LCD Integration with Arduino

Objective

The objective of this project is to use an Arduino Uno to measure distance using an ultrasonic sensor and display the readings on an LCD screen. The project integrates various components and uses block-based programming for functionality.

Components Used

1. Arduino Uno: The microcontroller board that acts as the brain of the system.
2. Ultrasonic Distance Sensor: Measures the distance to an object by emitting ultrasonic waves and calculating the time taken for the echo to return.
3. 16x2 LCD Display: Displays the measured distance in real-time.
4. Servo Motor: Rotates based on the distance measured (optional functionality).
5. Breadboard and Wires: For connections and circuit assembly.

Working Principle

1. Distance Measurement:

   • The ultrasonic sensor sends an ultrasonic pulse.
   • It calculates the distance by measuring the time taken for the echo to return.

2. Data Display:

   • The measured distance is sent to the Arduino.
   • The distance is displayed on the LCD in real-time.

3. Additional Features:

   • The servo motor can rotate based on distance.
   • RGB LEDs and sound notifications can indicate distance thresholds.

Code Functionality

1. Ultrasonic Sensor:

   • Reads the distance and stores it in a variable.
   • Prints the value to the serial monitor for debugging.

2. LCD Display:

   • Configured using I2C communication.
   • Displays the measured distance in centimeters.

3. Control Logic:

   • Updates the display every second.
   • Clears the screen after each update to refresh the data.

Applications

1. Distance measurement for robotics or automation systems.
2. Proximity detection for security or obstacle avoidance.
3. Interactive displays and learning tools.

Conclusion

This project demonstrates the integration of sensors, displays, and microcontrollers to create an interactive and functional system. The use of block-based programming simplifies the implementation, making it beginner-friendly. With further refinements, this setup can be extended to more complex applications like smart parking systems or autonomous navigation.
