Have the arduino read the serial port. When you receive an 'H', turn the led on. When you receive an 'L', turn it off. You can test this by itself using the serial monitor in the IDE.

On the vb side, you can use OpenSerialPort and write. The usb connections will appear as serial ports - it may take a little experimentation to find which one is connected to the arduino. Then you just need one button to send 'H' and another to send 'L'.

void loop()
{
   if(Serial.available() > 0)
   {
      char c = Serial.read();
      if(c == 'L')
      {
         Serial.print("samarth_gohil really needs to turn the lights off");
      }
      else if(c == 'H') 
      {
         Serial.print("samarth_gohil really needs to turn the lights on");
      }
