el15pjt 7:14cfb0df30e6 9 @brief The following code has been writen for the University of Leeds ELEC264501 embedded system project and is intended to
el15pjt 7:14cfb0df30e6 10 create a programe that can read a distance from an SRF02 sensor and then based aponn the reading disply the distance on the screen
el15pjt 7:14cfb0df30e6 11 and increment the LEDs and buzzer according the provision of a temperature sensor is also provied as a secondary function when no
el15pjt 7:14cfb0df30e6 12 object is detected with in range.
