Another approach, if cost and size are not major concerns, is to use Phidgets. They cover a huge range of functions, are high-quality, and dead-simple to use with Xojo, thanks to MonkeyBread plugins and the excellent Phidgets documentation. All you need is a USB port and you’ll be controlling motors and reading sensors in no time.

Mr.Ian Solved my problem with the Sub and End sub! But I am keeping this forum open, until I am able to accomplish the app! Currently having a bit of trouble installing the Pigpio library.
Never heard of these before! Thank you for the suggestion! I would try this if the project wasn’t due so soon 
Thank you Mr.Ian for helping me with this question on this forum and the other one as well!
