Arduino Ultrasonic sensor detection system

Project Details:

What is an Ultrasonic Sensor?

An ultrasonic sensor with Arduino is a combination used in electronics and robotics projects to measure distance. The ultrasonic sensor emits sound waves at a frequency higher than humans can hear (ultrasonic waves) and then listens for the echo that reflects back after hitting an object. By timing how long it takes for the echo to return, the sensor can calculate the distance to the object.

How it works:

The arduino is connected to an LCD screen to view live readable measurements from the ultrasonic sensor in centimeters and inches. The arduino is also connected to a buzzer that will beep when an object gets within 5 inches of the Ultrasonic Sensor. There is also an RGB light strip soldered onto the arduino that will emit green light until an object gets within 5 inches of the sensor, which then triggers the light to turn red.

Parts used:

1. HC-SR04 Ultrasonic Sensor 2. 1602 LCD Display 3. Any RGB light strip (Mine was MosterLED) 4. Arduino Uno 5. 5v piezo buzzer
