Hi, I am an experienced programmer in both Database programming and PC-Interfaces like RS232 and I can do your project in VC++,C#, or vb.Net. You could see similar works in portfolio. One of my works was very similar. It included an Arm Steadiness Tester working with RS232 and a database that records these data about athletes. I can do the database by MS Access and SQL commands. Hope this would be a good collaboration.
