### EMF Detector Averaging Code

 // Aaron ALAI EMF Detector May 28th 2009 VERSION 1.1// aaronalai1@gmail.com// contains code for averaging sensor data#define sample 300                    //this is how many samples the device takes per reading                                                        //more information for #define http://arduino.cc/en/Reference/Define int inPin = 5;                                  //analog 5float val;                                         //where to store info from analog 5int pin11 = 11;                              //output of red ledint array1[sample];                      //creates an array with number of elements equal to "sample"                                                        //more information about arrays http://arduino.cc/en/Reference/Arrayunsigned long averaging;         //the program uses this variable to store the sum of each array it makesvoid setup() {   Serial.begin(9600); }void loop() {                    for(int i = 0; i < sample; i++){              //this code tells the program to fill each element in the array we made with   array1[i] = analogRead(inPin);       //information from the antenna wire coming out of the Arduino   averaging += array1[i];                      //more information about for loops http://arduino.cc/en/Reference/For}                                                               //the averaging line is simply saying: add averaging to whatever is in array position i                                                                //averaging += array[i] is the same as averaging = averaging + array[i]                                                                //for more information about += http://arduino.cc/en/Reference/IncrementCompoundval = averaging / sample;                   //here the program takes the sum of all numbers in array1, and divides by the number of elements "sample"val = constrain(val, 0, 100);               //this constrains the variable value to between two numbers 0 and 100                                           val = map(val, 0, 100, 0, 255);      //for more information about constrain http://arduino.cc/en/Reference/Constrain       analogWrite(pin11, val);                //the map statement tells the program to map out 0-100 to 0-255, 255 is                                                               //the threashold of analogWrite for more information about map http://arduino.cc/en/Reference/Map    averaging = 0;                                 //this line of code sets averaging back to zero so it can be used again}
