Picking up tetra's is going to be as easy as picking up a person of the opposite sex.
While a select few will master it; others will be bumbling maroons..

PC Parallel Port Circuit
Hey everyone, I have a PC related question, so hopefully I put this in the right forum.
You know how you can use your computer to set the status of your parallel port pins? EG 0-+0.7V on a data pin is logic '0', and +2.4 - +5V on a data pin is a logic '1'. You also know how you can use these pins and the ground pins to power electric circuits? Well I was wondering how to externally set the pins to a logic 1 or 0, using a circuit. I want to know because I need to make a receiver for a laser communicator device and I need to be able to set the status of a pin (to be read by the computer) using an electric circuit. Thanks  |
