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 ...

WORKING VIDEO: human-following-robot.mp4 Conclusion: Building a human-following robot using Arduino and three ultrasonic sensors is an exciting and rewarding project that combines programming, ...

Smart Blind Stick using Arduino Circuit Diagram The below circuit diagram shows the complete hardware wiring setup of the Arduino-based Smart Walking Stick for the Blind people, detailing how the ...

Project description In this project I will introduce you to the HC-SR04 Ultrasonic sensor. It works by sending sound waves from the transmitter, which then bounce off of an object and then return to ...

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle he’s made a device which can warn people around you if they’re too close for comfort.

We present a novel method for continuous activity recognition based on ultrasonic hand tracking and motion sensors attached to the user's arms. It builds on previous work in which we have shown such a ...
