Vehicle Detection: Ultrasonic sensors monitor each parking slot and send data to the Arduino Uno. Slot Availability Display: Real-time updates shown on an LCD using I2C communication.

An Arduino compatible board (e.g. Arduino UNO): Arduino UNO / Arduino Mega A HC-SR04 ultrasonic sensor / A Ping))) ultrasonic sensor: HC-SR04 (Optional - For aqqurate distance values) A DHT ...

Here we discussed about the pinout and different modes of ultrasonic sensor module and how it works. Also we learned how we can use ultrasonic sensor module with Arduino.

Also, check all the Arduino-based Robotics projects by following the link. The working of a human following robot using Arduino code and three ultrasonic sensors is an interesting project. What makes ...

Ultrasonic sensors are used to detect the presence of obstacles, calculate the distance to these obstacles, and relay this information to the driver through visual and auditory cues. This research ...
