/**
    Temperature Sensor for hw6
    main.cpp

    Purpose:    Read signal from TMP36 connected to pin20
                Display output voltage to terminal
                Display difference in mV of output voltage to starting voltage on 2x 7-Segment Displays
                    See outputs for pin configuration
                Toggle switch connected to pin07 to convert displays to degC
