How to use LabView to control a RC car via LPT1?

[qatar.engineer]

Hello,

We are working on a project of interfacing..

We are required to use labView to control a RC toy car through a LPT1.

Now, this seems easy to many of you, but our problem is that we do not know anything about interfacing, we have never used lab View before.

does anyone have the lab View program.?

Get the RC Car with Wireless Remote Control. Remove the Remote Control Cover. You can see the switch connections used for front, back, left, right. Solder wires to the switch output.
Now in labview use outport function. If you set 01h you will get first bit 1.
With a BC547 or any other simple driver circuit connect first data bit (D0) of Parallel port to Front Key output. Ensure Logic High and Logic Low Condition for default output.
Likewise connect with Back, Left and Right Key Outputs.
In Labview program use four buttons looks like your remote controller. When you press Front Button in software send 01h. For Back 02h, Left 04h and Right 08h.
Make sure only one key is pressing and one signal out at any time.

Try This.
