I trust you have someting programmable like an SX Tech or ProfDevelopment board and an SX-Key ? To do simultaneous functions efficiently, you will want to use a scheduler.... kind of like a simple minded real-time operating system. You can find an example in my previous submission to the Parallax contest. It is well commented, and if you are rusty on interrupts, then becoming familiar with that is an absolute "must". So study that example, and we'll go from there.
