Building the EMF bug detector

We are now going to dive into the core of this project and configure the project so that it can detect EMF activity around the antenna.

The following is the complete code for this project:

// Required libraries
#include <Wire.h>
#include <LiquidCrystal_I2C.h>

// Number of readings
#define NUMREADINGS 15

// Parameters for the EMF detector
int senseLimit = 15;
int probePin = 0;
int ledPin = 7;
int val = 0;
int threshold = 200;

// Averaging the measurements
int readings[NUMREADINGS];               
int index = 0;                           
int total = 0
int average = 0;                         

// Time between readings
int updateTime = 40;

// Create LCD instance
LiquidCrystal_I2C lcd(0x27,20,4);

void setup()
{
  // Initialise LCD
  lcd.init();

  // Set LED as output
  pinMode(ledPin, OUTPUT);
 
  // Print a welcome message to the LCD
  lcd.backlight();
  lcd.setCursor(0,0);
  lcd.print("EMF Detector Started");
  delay(1000);
  lcd.clear...
