//TemperatureRecorder class //Written by Napoleon Leoni, February 2014 //This class takes a pointer to an LM75B sensor on the MBED //application board and reads it temperature value, keeps track //of the max and min values (since a last reset of the values) and also //keeps a circular buffer of recorded temperature values
