This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD.

About This project is an Arduino-based flood monitoring system using an ATmega328P, ultrasonic sensor, LCD display, and buzzer.

Create a smart blind stick using Arduino to help visually impaired individuals navigate safely. This DIY project uses an ultrasonic sensor, buzzer, and LED indicators to detect obstacles and provide ...

What this project does is produce seven different tones (middle C, D, E, F, G, A, and B) with only an Arduino UNO, ultrasonic sensor, force-sensitive resistor (or push button), and piezo buzzer.

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 ...

Ultrasonic sensors are used to detect the presence of obstacles, calculate the distance to these obstacles, and relay this information to the driver through visual and auditory cues. This research ...
