/* Grove - Temprature Sensor demo v1.0
*  This sensor detects the enviroment temprature,
*  Uses a Arch-Pro board with Grove Base Shield
*  Connect the Grove Temperature sensor to A0 and
*  connect a Grove 4 digit LED display to the UART connector
*  The temperature will be displayed in Celcius
*  Modified by David Bottrill from the original Arduino code
*  Reference: http://www.seeedstudio.com
