 		 #121689 - The diagram does not work
Responding to: ???'s previous message
For some reason, the diagram appears correctly when im typing the message but oh well let me just put it into words,

1.Vcc(+5V) is connected to the +ve terminal of the Buzzer.
2.P1.0 of MCU is connected to the -ve terminal of the buzzer through a current limiting resistor.

Does logic "low" represent 0V?            01/01/70 00:00      
   The diagram does not work            01/01/70 00:00      
      What current are we talking about?            01/01/70 00:00      
      More details needed!            01/01/70 00:00

      Yes, but...            01/01/70 00:00      
         bear in mind            01/01/70 00:00      
            Of course, but...            01/01/70 00:00      
         forgot to mention: cookbook was for a piezo buzzer            01/01/70 00:00      
            In such a case...            01/01/70 00:00

                  Update            01/01/70 00:00      
                     Please do as I have asked: connect the buzzer            01/01/70 00:00

   Barbecue?            01/01/70 00:00      
   Type of buzzer            01/01/70 00:00      
      who knows how much power, how big spikes            01/01/70 00:00      
      Again...            01/01/70 00:00      
         Yeah            01/01/70 00:00

               just guessing            01/01/70 00:00      
                  guessing the current is below 5A...            01/01/70 00:00      
                     then what if it is 1uA            01/01/70 00:00      
                        Sorry.            01/01/70 00:00      
                     We just do not want to guess!!            01/01/70 00:00      
                        Sorry.            01/01/70 00:00
