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 ...

Ultrasonic Sensor The whole idea of this “pseudo-theremin” is to obtain the proximity to the nearest object (like a hand) via an ultrasonic sensor, turn that into a playable frequency, generate a ...

🚨 Arduino Alarm System with Ultrasonic Sensor 🚨 I recently built a simple alarm system using an Arduino Uno and an ultrasonic sensor! The system detects motion or obstacles within a set ...

One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a Linux computer. The end result is a virtual touchscreen that can be made at home.

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 ...
