So, you can expect to see an rapid roll of numbers that are \"Pre-fixed with a Letter\".\r\nthis \r\n\r\nThe Letter identifies what that number means. \r\n\"S\" Means Signal\r\n\"B\" means BPM Number\r\n\"Q\" is a Heart-rate Variability Number\r\n\r\nFor example:\r\n\"S511\" or \"S###\" is the raw Signal number for the Pulse Sensor.  It's simply the intesty of light the optical sensor literally sees.   \r\n\r\n1) Try Moving your finger on and off the sensor.  When you cover and uncover the sensor, you'll see that you can kind of control the Signal the \"S\" + \"Some Number Between ~0-1000\".  \"S515\" for example. \r\n\r\n**The Serial Monitor Read-Out\" window** is simple a raw and live feed from Arduino to the Mac App.  The Visual Level Indicators, turn this live numbers feed into a \"Digital Level\".\r\n<img width=\"1161\" alt=\"screen shot 2015-07-20 at 11 04 17 am\" src=\"https://cloud.githubusercontent.com/assets/3867041/8779031/250e2c8e-2ecf-11e5-9c09-c74d072a79f7.png\">\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n "}}
