Make sure the wire (antenna) is connected to the Analog pin of Arduino. Let's say A0. Use the function analogRead(0) and store it in a variable. Output that digital value on digital pins. To check if you are getting any values or not, open the serial monitor and print the values using Serial.println(); Here's the rough sketch void setup()
{
Serial.begin(9600);
}
void loop()
{
A = analogRead(0);
Serial.println(A);
}
