You want to use LabVIEW to digitally control LED lighting using a 24 volt system.

Here turn on the LED powered by 24 volts, given current limitation about 8ma by applying digital depression to light the LED and digital camera HI (open) to turn it off. I have a USB 6009, that I use with my laptop, but according to the specification, it may not exceed 5.8 volts on a digital output. I need at least 4 outputs digital and digital 9 control LED 9. What equipment do I need. I have access to a desktop as well.

Thank you, Alexander

To drive the 9 LEDs, using the ULN2003.  Google it.  Digital output you feeds the ULN2003 and its production feed the LEDs.  You must always current limiting resistors inline with LED.  The ULN2003 can handle input/output 7.  So, you will need two of them.  Much simpler to have 9 transistors with base resistors.

  • Which account you want to use to run this program?

    A week ago, just after installation of Microsoft Update, when I start my computer, a box came who said: run as.  Which account you want to use to run this program? [x] current [of user\Owner] protect my computer and data from unauthorized program activity. This option can prevent computer viruses from harming your computer or personal data, BUT selecting it might cause the program to function properly. Current use is already checked, and my options are to check I want is not protected, or cancel. I tried all the options, or just close the box. What is the devil? Why should I see it every time I start my computer? And, more importantly, why would I want to when, "selecting risk the program work correctly?" How can I get rid of this annoying box, since I already have Kaspersky as a guard dog? Thanks, Tess

    No, you are not condemned.

    To make the warning "diagnostic mode" Begone, re - run msconfig and select the radio to "Normal startup" button (cela re - automatically checks the Java update box, as well as all the other boxes you might get UN-ticked).

    The way you described your original message is a bit confusing.  Messages request 'which account you want to use' - what are the choices presented to you?

    Run as.  Which account you want to use to run this program? [x] current [of user\Owner]

    Is the account that you sign normally called "owner"?

    You have an x in the box in front of "Current user" - If the current user IS 'Owner' what does the other box reference?  It may be a better representation of the pop - up:

    Run as
    Which account you want to use to run this program?
    [] Current user / owner
    [] Protect my computer and data from unauthorized program activity. This option can prevent computer
    viruses from harming your computer or personal data, BUT selecting it can cause the program to
    work correctly.

    That is, we really give you a choice of the accounts, but only the current account or anything.

    When you go to control panel > user accounts, is the account that you are connected to a "Computer administrator" or "limited account"?

    You need to do some detective work more:

    • In the Startup tab, run msconfig and uncheck ALL items.  If the "RunAs" message does not come to the top, you know that one of these elements is the culprit.  Selectively, double-check items (you can do as a group to save time re-boot) and re-start until you determine what startup item causes the error.  Once you have identified the startup item that is causing the problem, post back with his name and I will try to help you determine what to do about it.
    • The "RunAs" message continues even with all uncontrolled startup items, you going to dig deeper.  Reset things to normal by selecting the option "Normal startup" button and follow the steps.  I'll look at other things that start when Windows starts and see if I can suggest the next steps.

  • Upgrade to CC, but that you want to use PS7 on laptop

    I want to upgrade to PSCC and have two offices (two locations), which are the two I use PSCC on, but also to use my computer laptop a lot between the two. I especially make digital scrap booking and photo editing. I have to use the PS7 on my laptop that you can't have PSCC on two computers. (I don't want to have to switch back) How can I make brooms that I create in usable in the PS7 PSCC. I have brushes that have been created in PRIVATE security firms and are not compatible. I know that there is a change in 2014, but looking for a viable solution to the problem of having multiple computers

    In my view, the answer is Yes, you would have to make the brushes in photoshop 7, if you want to use both cc and ps 7.

    You could also install photoshop cc on a third computer, you will need to just sign one of the others when you want to use.

    Make sure that Firefox is not set to run as administrator.

    Right click on the desktop Firefox shortcut and choose "Properties".

    Make sure that all items are disabled in the tab "Compatibility" in the Properties window.

    • Privilege level: "Run this program as Administrator" should not be selected
    • "Run this program in compatibility mode for:" must not be selected
