ESP32 Ultrasonic Sensor Project
The ESP32 Ultrasonic Sensor project demonstrates how to interface an ultrasonic sensor with an ESP32 microcontroller to measure distance based on the time it takes for sound waves to travel to an object and back. This project is commonly used in robotics and automation for obstacle avoidance and distance measurement applications.

Instructions
Setup:
Initialize Serial communication using
Set pinMode for
Operation:
- Generate a short pulse on the trigPin to initiate the ultrasonic signal.
- Measure the duration of the pulse received on the
- Calculate the distance based on the duration of the pulse and the speed of sound.
- Print the distance to the Serial Monitor.
Output:
Continuously display the distance measurements.
Distance is measured in centimeters (cm).
