🔹 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 ...

An ultrasonic sensor (HC-SR04) is wired to a Raspberry Pi Pico. The distance of the obstacle in front of the sensor is displayed in the serial monitor. A buzzer connected to GPIO19 will change ...

In this project, we will build Human Following Robot using Arduino and Ultrasonic Sensor. This robot can track and follow a person autonomously, making them useful in various scenarios like assistance ...

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.

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ...

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.

A new generation of miniaturized ultrasonic time-of-flight (ToF) sensors enable new application areas and use cases for proximity sensing and presence-detection technologies.
