This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Through this hands-on, project-based approach to learning, you'll grasp a solid understanding of Arduino components like ultrasonic sensors, motor drivers, servos, and transistors.

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.

10 Simple-But-Fun Projects to Make With Arduino John Boxall, author of the new book Arduino Workshop, shares a few of the projects from his book on how to get started with the microcontroller.

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 ...

In this project, students will design and prototype a novel wearable sensor for continuous physiological monitoring (e.g., heart rate, blood pressure, glucose, etc.). Besides the conventional ...
