// EPOCH PROJECT#16: "PLOTTING AUDIO WAVEFORMS"
// IN THIS PROJECT WE'LL MEASURE LEVEL OF SOUND DETECTED BY THE MICROPHONE.  WE'LL PRINT THE DATA TO BOTH THE SERIAL MONITOR AND DATA PLOTTER
// CONNECTIONS:
// PLACE A JUMPER ON THE MICROPHONE JUMPER.  THIS WILL SHORT THE "MIC" MICROPHONE OUTPUT TO THE "A0(A)" A0 LINE ON CHIP-A 

int sound = 0;         // WE'LL STORE OUR SOUND SAMPLING DATA IN THIS INTEGER

void setup() 
{
Serial.begin(9600);   // INITIALIZE THE SERIAL MONITOR/PLOTTER
}

void loop() 
{
 sound = analogRead(0);    // TAKE A SAMPLE FROM THE MICROPHONE AND PLACE IT IN sound
 Serial.println(sound);    // PRINT THE SAMPLE DATA TO THE SERIAL MONITOR AND SKIP TO THE NEXT LINE (HENCE THE ln AT THE END OF THE PRINT COMMAND)
 // delay(10);             // THIS DELAY IS COMMENTED OUT FOR NOW.  READ THE NOTES BELOW.
}

// THAT'S IT!  LOAD THE PROGRAM, AND OPEN THE SERIAL MONITOR OR PLOTTER


// NOTES
// WHEN YOU OPEN THE SERIAL MONITOR, YOU'LL SEE THE DATA PRINT OVER AND OVER AGAIN.  WHEN THERE'S NO NOISE, YOU'LL SEE VALUES BETWEEN 0 AND 20 (CLOSE TO 0V).  START MAKING NOISE, AND YOU'LL SEE THESE NUMBERS JUMP
// NOW OPEN THE PLOTTER AND DO THE SAME THING.  YOU'LL SEE A PRIMITIVE VIEW OF WHAT THE SOUND WAVEFORM LOOKS LIKE.  NOICE THAT THE SCALE IS ALWAYS CHANGING DEPENDING ON HOW MUCH NOISE IS BEING PICKED UP
// TRY COMMENTING THE 10ms DELAY BACK IN AND WATCH HOW THE SERIAL PLOTTER RESPONSE.  TRY MAKING THE DELAY EVEN LONGER.  REMEMBER, YOU'LL LEARN MORE BY EXPERIMENTING!
