title: Arduino uno r3 does not reset when pressing reset button
body: <p>I am starting off with an Arduino Uno and am able to flash some sketches via the Arduino IDE. </p>
  
  <p>Something confuses me though... When I press the reset button on the board I was under the impression that my currently flashed application is removed. That is not the case. It still executes the last flashed application. Is that supposed to happen?</p>
  
  <p>Also when I flash the "bare minimum" sketch with no code instructions, the on board LED on pin 13 is constantly active. Is that the default behavior?</p>
