PC Running QBASIC controls 7-Segments via Parallel Port [Project]
posted October 15 2014 16:48.18 by Giorgos Lazaridis

Its time to remove the dust from your old DOS-operated PC, plug it in and let it rock'n roll! I remember myself how happy i was when i managed to control a PIC with serial interface using QBASIC... This instructable from Bhavyansh Mishra shows how to use QBASIC to control three 7-Segment displays using the parallel port. The circuit is basic and very simple to prototype on breadboard. So if you happen to have such an old PC, GO AHEAD!!!

If you remember this screen, you are old!
