Ultrasonic Sensor Project

The Ultrasonic Sensor project demonstrates how to use an ultrasonic sensor with an Arduino Mega to measure distances based on the time it takes for sound waves to bounce back from an object. Ultrasonic sensors are widely used for proximity detection and distance measurement in various applications.

Components Needed

• Arduino Mega
• Ultrasonic Sensor (HC-SR04 or similar)
• Jumper Wires
• Breadboard
• Power Supply

Circuit Setup

Connecting the Ultrasonic Sensor to Arduino Mega:

Instructions

Code Upload:

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Mega.

Testing:

Open the Serial Monitor in the Arduino IDE (set to 9600 baud).

Observe distance measurements displayed in centimeters (cm) as detected by the ultrasonic sensor.

Place objects at different distances to verify accurate distance readings.
