Step-By-Step Building the Programming Trainer |
The trainer is a tool that is handy to use while you test out your programming on these parallel port projects. It features 8 light emitting diodes (LEDs) and 5 push-button switches that can interact with your programs. It can be built for under $15.00. It plugs into the parallel port and the LEDs can be powered directly off that connection without an external power source. To see a close up photo of the trainer, click on the image in the title at the top of this page. To view a schematic of the the trainer, click here. The trainer pictured is housed in a plastic box that used to contain drafting instruments. For information about the parallel port, how it works, and how to address it with a QBasic program, click here. Once you get the trainer built, you can try it out with the programs shown below. You can download the program in three formats: QBasic Source Code (QBasic required) Text File
