Hey, I'm new to all this stuff so please bare with me. About 2 or 3 years ago i made a robotic arm with the help of some of you guys on this forum. So anyways i used the Parallax Server Controller USB (This one: http://www.antratek.de/images/PSC_usb_150.jpg) and i was wondering instead of the computer sending "signals" out to the chip, could i send a "signal" from the chip to the computer? I was thinking about connecting a toggle switch to the female pin and when i turn the switch on it would toggle for example, a letter on the keyboard. Is there a software or anything that would make this possible, instead of purchasing the actual chip/card.
