Hey there! I'm a 4th year Computer Engineering Student at UWO and I cannot for the life of me figure out a way to use my serial port, parallel port, or audio ports on my PC to provide a simple variable 0-5V Output! The project will simply involve providing three different devices with 0-5V depending on feedback provided from software. All I need to know is if there is a relatively simple way to use ANY port of my PC to output zero to five volts. The software can be interfaced with any low-high level programming language. The project at this point is completely open to suggestions, so any suggestions that you have are more than welcome! Sincerely, Stephen
