   100 ohm resistor (the pin 2 trigger) and hear a 2 second run of your buzzer.   
      
   I watch a dozen or more videos looking for a good monostable 555 timer   
   tutorial, so far this is the best I can find, no completely happy but it   
   does describe a monostable 555 operation. I could not find one with a   
   native English speaker.   
   This is 12 minutes but worth your time to learn.
