/**
    Temperature Sensor for hw6
    main.cpp

    Purpose:    Read signal from TMP36 connected to pin20
                Toggle switch connected to pin07 activates SD logging
                Log: Time Elasped, Current Voltage, Current Temp, Delta Temp
                Finish log -> save file and send to USB serial port
