The sensors attached to the Arduino had an approximate scanning range of 3m, and the ultrasonic units were modified to broadcast an analog signal at 40 kHz.

The Arduino continuously reads the distance measurements from the three ultrasonic sensors: front, left, and right. Based on the sensor readings, the car's behavior is determined using conditional ...

🔹 Project Details: Smart LED Distance Indicator using Ultrasonic Sensor and Arduino 📌 Introduction This project is a real-time distance indicator using an HC-SR04 ultrasonic sensor and LEDs to ...

The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the collaboration of ...

SJEC-AICTE IDEA lab in collaboration with Department of Electronics and Communication Engineering (ECE) at St Joseph ...

For the physical feedback, Denver has made some vibrating boxes that you put in your pockets. An Arduino polls the ultrasonic sensors and provides feedback via the boxes. This completely frees up the ...

Ultrasonic sensors have become commonplace thanks in considerable measure to adoption in early-stage autonomous driving vehicles. Ultrasonic technology uses mostly inaudible sound waves (starting at ...
