visual basic > serial communication(or any communication port of the computer available preferred usb or serial) > circuitry w/th 8 bit led ready


if i send 50 the output on led will be 110010

i hoped sombody can help me
 

It is perfectly possible.
To receive the commands at peripheral side you can even build an microcontroled based hardware or only a based shift registrer circuit.
