Now, the venerable ultrasonic sensor joins the gallery of classics given a size change treatment, like the 555 timer we’ve seen two different takes on, or perhaps that one Arduino Uno.

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 ...

The Arduino code performs the following tasks: Sweeps the servo from 0° to 180° and back. At each angle, it triggers the ultrasonic sensor to measure distance. Depending on the measured distance: ...

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 ...

Arduino enthusiasts may be interested in a new single pixel scanning camera which is powered by an Arduino Uno combined with a TCS34725 sensor available from online stores such as Adafruit.

In this research article we will explore the production of the Smart Trash Can System using the Arduino ultrasonic sensor and lire detector. Published in: 2021 8th International Conference on Signal ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.
