2. HCSR04 Ultrasonic Sensor Pinout Source: Circuitdigest The Ultrasonic Sensor has 4 pins: - VCC, Trig, Echo and GND. The Pinout explanation is given as below HC-SR04 Ultrasonic Sensor Pinout VCC - The supply pin of the HC-SR04 Module. GND - This is the Ground pin of the module Trig - This is the trigger pin of the HC-SR04 module Echo - This is the echo pin of the HC-SR04 sensor module.

3. Working principles of Ultrasonic sensor Source: Circuitdigest The ultrasonic sensor operates by emitting high-frequency sound waves and detecting their reflections. It comprises a transducer, which both emits and receives ultrasonic waves, along with signal processing circuitry to measure the time taken for the waves to travel and return.

4. Circuit connection of Ultrasonic sensor Source: Circuitdigest Connect the ultrasonic sensor's trig and echo pins to Arduino pins 4 and 5, respectively. This configuration allows the Arduino to trigger the sensor and measure the time taken for the echo pulse to return.

5. Arduino Integration with Ultrasonic Sensor and LCD Display Source: Circuitdigest Arduino Code: Initialize serial communication, set up trigger and echo pins, measure echo pulse duration, calculate distance based on sound speed, and display on Serial Monitor. LCD Display Addition: Connect I2C LCD display to Arduino using SDA, SCL, VCC, and GND pins for real-time distance display alongside serial output.
