About this project

This is one of the most basic EMF Detectors YOU can make! Using nothing more than an Arduino, some basic electronic components and a paperclip.

(Note: Use the paperclip as the antenna. For a higher sensitivity, replace the 100KOhm resistor for a stronger one)

Code

Arduino CodeArduino
int inPin = 3; 
int var = 0;
int pin11 = 5;

void setup() {
  Serial.begin(9600);
}
void loop() {
  var = analogRead(inPin);
  if(var >= 1){
    var = constrain(var, 1, 100;                        
    var = map(var, 1, 100, 1, 255);
    analogWrite(pin11, var);
   }else{
       analogWrite(pin11, 0);                     
  }
 Serial.println(var);
}
