Mounted on a rotating servo motor, the ultrasonic sensor emits sound waves and measures the time taken for echoes to return from objects, providing precise distance calculations and proximity ...

The provided Arduino code performs the following actions: Initializes pins and serial communication. Measures the distance using the ultrasonic sensor and calculates the distance in centimeters.

🚨 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 ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the collaboration of ...

The traditional single sensor alarm system has been difficult to meet the requirements of multiple pollutants detection at the same time, so this research proposes a multi-sensor integrated ...

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.
