asked on

program a usb light to turn on when needed

I need to make a  vb6 program that will turn on a flashing 120 volt light and siren when the user enters a certain value into the vb app.  Any suggestions.

What interface hardware are you intending to use?

USB or COM on PC.
Thank you.  But what specific piece of hardware are you going to use as the interface device?  Are you going to use an NI USB to digital I/O board, or are you going to kludge up something from a USB printer port, or have you got some other piece of hardware in mind?

The software will follow from the hardware you choose.

sorry I don't really know what hardware I want to use all I know is I want to be able to turn on a flashing 120v red light and siren when the user clicks on the red button on my vb6 application.
