    Hi everybody,

    I would like to write a program in "Visual Basic" containing one "on" button and one "off" button. When I press the "on" button the LED bulb should glow and pressing "off" button the LED should not glow. How do I send signals? Help me please

    Thank you

    How do you plan to connect the LED to the computer? Probably the easiest would be to use one of the handshake lines on the serial port if you have one...
