The set-up process is very simple, and best understood by referring the wiring diagram. If everything goes right,you should see the burning eye of the red LED when there is no object in the safe-zone ...

🔹 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 ...

This project uses an HC-SR04 ultrasonic sensor to measure the distance of an object. If an object is detected within a specific range (e.g., 10 cm), the SG90 servo motor rotates to 90 degrees, the ...

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.

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]&#82… ...

40-KHz ultrasonic transmitter and receiver pair (40T/R-B/W) Schematic of the HC-SR04 module . Get to the point. In truth, my intent is not to provide a new translation of some well-worn “Arduino & ...

Arduino Uno – Powered Parking Guidance System with Ultrasonic Sensors" is a smart and innovative solution for simplifying the parking process in crowded urban environments. This paper leverages the ...

This device's affordability is one of its key benefits. The Arduino board is used as a wearable. This is fitted with a module-sized set of ultrasonic sensors. The sensor allows people who are blind to ...
