This project uses an **HC-SR04 ultrasonic sensor** with an **Arduino Nano** to measure distance. When an object comes too close, the **LED** lights up, and the **buzzer** sounds an alert.

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 the proxim ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Inside the light is an Arduino Nano, which reads from the ultrasonic sensor mounted underneath the enclosure and lights up the appropriate LED depending on the car’s distance.

This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic sensor, LEDs ...
