I would like to apoogize for my comment about thing being obvious to me. I have over 20 years experience as an Electronics Technician specializing in board level troubleshooting so there are circuit problems that I see that are very obvious to me just by looking at the circuit. What I would consider obvious may not be apparent to you so you just keep asking any question you like. I am here to help with obvious problems as well as the not so obvious problems. I apoligize if this offended you in any way as that was never my intention.

Hello!
you don't need to apologize. anyway i understood that it was not meant to offend me, and i also know that learning can be though sometimes and i am prepared for that. my goal is to have a considerable knowledge in software practice. and thank you for the help that you give me.

Your 555 is trigger is wrong, you need to better understand how a 555 works and what mode you want it to run in.
Use this link, correct your schematic to this based on your system needs and report back.

Thanks Chris for the information you posted. I would agree that he needs to review this information so he can learn about the 555 timer and its configurations. This can only help him in his quest to understand designing and electronics even more. I did post a corrected version of his circuit for him and posted sticky notes to the things I changed. The circuit I posted (just in case you would want to look at it) has the correct configuration but I didn't go through all the math to select the resistors. I just arbitrarily selected 2 that would allow the LED to switch fairly quickly so he could see that his circuit did work.

hi
can you tell me where i can find a complete documentation on how to use( connection and settings) the instruments( function generator,oscilloscope,wattmeter.....) in Multisim?
thanks

There is a Help file that should be able to give you this information. Goto HELP>MULTISIM HELP. If you can't find what your looking for in the helpfile then there is a documentation folder within the National Instruments folder that should contain a Getting Started Guide and a User's Manual. These two reference documents should have all the information that you need about these instruments.
