The PC Serial Port Receiver circuit


Posted on Feb 5, 2014

This circuit requires physical connections be made to the computer`s serial port (COM1 or 2). To the best of my knowledge, it is difficult to cause damage to yourself or your computer by improper connections to this port, but there is no guarantee that damage will not result. Use caution when making any external electrical connections.
