1. The **HC-SR04** emits ultrasonic waves and measures the time it takes for them to bounce back. 2. The **Arduino Nano** calculates the distance using the speed of sound. 3. If an object is detected ...

Description: This project utilizes an Arduino Nano along with an ultrasonic sensor to create a distance-based LED color changer. The objective is to demonstrate how the color of LEDs changes based on ...

HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using this sensor. Device is very simple and ...

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 ...

Enclosed are the ultrasonic sensor, a temperature sensor and an LED indicating the power status. On the other side of the CAT5 cable can be found an Arduino compatible board with an XBee shield ...

This study focuses on the development of an obstacle avoidance robot controlled by an ultrasonic sensor. The robot utilizes robotics and artificial intelligence techniques to improve obstacle ...

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 ...

In this mode, you can interface the HC-SR04 ultrasonic ping sensor with a servo motor and the main board (Only some reward tiers include the extra servo motor PCB and servo motor kit).
