YourDuinoStarter Example: Controllable Time Strobe LED V3 "SpinnerStrobe"

  - WHAT IT DOES: Flashes an LED with variable timing set by a potentiometer

   - Can "stop" motion of rotating wheels, fans etc.

   - Works best with a High Output LED like this:

   http://yourduino.com/sunshop2/index.php?l=product_detail&p=458

   - Can tell you the "RPM" of a device with 1, 2 or 3 "legs"

  - INFO: See https://arduinoinfo.mywikis.net/wiki/SimpleStrobe

  - SEE the comments after "//" on each line below

  - CONNECTIONS:

   - LED: Pin 13

   - Potentiometer: Pin A2
