What is the minimum hardware required to light a LED?

Hello

I want to have a few physical outputs very basic of my labview program, which can be summed up as "what is the minimum hardware necessary to light a lamp?

The COM port can be used as a base i/o port, pins can be toggled?

Some people seem to use Arduino to connect, how are easy to implement?

And my last option I know is a dedicated i/o card. I guess that they are plug-and-play, but overkill for my purposes.

See you soon,.

You can easily use a COM port. There is a property node for control of handshake lines. Not sure that the com port is not TTL levels, not you? The voltage levels can be as large as +/-15.
