/*  One patch of aluminum foil should be connected to 
    12 (A11), 6 (A7), 9 (A9) or 10 (A10). 
    The other patch should be connected to a ground (GND)
    Adjust the code for your A-pin, upload,
    and read the serial monitor to see the values.

// The first section is where to declare global objects and call up additional files the program needs to use.  
int aluminumFoil = A11; //select your input pin for your sensor 
int foilStorage;  //this name (variable) stores readings from the sensor

  // The second section is for things that only need to be done once at the beginning of the program.  
  
  // initialize serial communication at 9600 bits per second:
  // this allows messages to be sent to the computer
  Serial.begin(9600);
  pinMode(aluminumFoil, INPUT); //sets sensor to input
  digitalWrite(aluminumFoil, HIGH); //initializes the sensor

while the program is running. The code is executed in the order coded. */

}

// The fourth section is for functions that are called up by the third section.
