USB Human Interface Device

[fubag]

Hi Guys,

I needed some advice/recommendation on a very simple design/device I could use for my project.

Essentially, I'd like a HID USB push button, similar to the Easy Staples button. Basically a switch button that I could interface as a COM device and integrate into my LABVIEW program. My end goal is to have this button stop a built-in stopwatch in my program, so I can measure the reaction time (in ms) for a subject.

What do you guys suggest? Are there products out there that you could recommend that would do this job, or would it be easier to make something from scratch?

Thanks a lot!

You can just purchase USB to RS232 converter ( cost about Rs250.00) use DSR and RTS pin to access a bit
