Hello Again, Thank you. I will look into it. I know very little about node.js. I have been following some books on the BBB. I just know how to run .js files with node. That is about it for now.
Seth P.S. I have used the ADC from the Adafruit_BBIO a long time ago but I stopped once things got odd. I was having trouble calling ADC with success. Anyway, thank you and I will check it out.
