Question

I need to create a cpp file and a header file that work with the given code. Need super help. Coding is in C++ - We are trying to program an arduino to read out the proximity sensor HCSR04.

#include "HCSR04.h"//include your proximity sensor library

#define echoPin 8 // This is the echo pin
#define triggerPin 9 // This is the trigger pin

HCSR04ProxSensor distanceSensor(echoPin,triggerPin);//here we call the constructor to instantiate a sensor named "distanceSensor"

/***************************setup function****************************************************/

void setup() {
Serial.begin(9600);//start serial communication
}

/***************************main loop*********************************************************/

void loop() {
Serial.print("The distance is : ");
  
float distance = distanceSensor.readSensor();//here we call the 'readSensor' method to determine the distance
Serial.print(distance);// send the measurement to the serial monitor
Serial.println(" cm");
  
if (distanceSensor.getLastValue() - distance > 1) {Serial.println("object is approaching");}//here we call the 'getLastValue' method to determine the direction of motion
if (distanceSensor.getLastValue() - distance < -1) {Serial.println("object is retracting");}
  

delay(500);
}
