- 1. HOW TO INTERFACE ARDUINO WITH AN ULTRASONIC SENSOR? Source:
- 2. HCSR04 ULTRASONIC SENSOR PINOUT Source: 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: 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: 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. ULTRASONIC SENSOR AND LCD DISPLAY Source: 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.
