Distance Measurement System with Arduino Uno R3

Project Overview: The project aims to create a distance measurement system using an ultrasonic sensor (HC-SR04), Arduino Uno R3 microcontroller, LED, and resistor. The ultrasonic sensor emits sound waves and measures the time taken for the waves to bounce back from an object, allowing the Arduino to calculate the distance based on the speed of sound. The LED provides visual feedback to indicate the distance measured.
component
1. ultrasonic sensor (HC-SR04):The ultrasonic sensor HC-SR04 is a popular choice for distance measurement in Arduino projects. It works by emitting high-frequency sound waves (ultrasonic pulses) and then measuring the time it takes for these waves to bounce off an object and return to the sensor. This time measurement can be used to calculate the distance between the sensor and the object using the speed of sound in air.
2. Arduino Uno R3 :The Arduino Uno R3 is a microcontroller board based on the ATmega328P chip. It has digital input/output pins, analog inputs, a USB connection for programming and power, a power jack, and a reset button. It serves as the brain of the project, processing data from sensors and controlling output devices based on programmed instructions.
