00002 LAB EXERCISE - Environmental sensors measurements
00003  ----------------------------------------
00004     In this exercise we will read the environmental sensors on the Nucleo sensors shield (X-NUCLEO-IKS01A1)
00005     with the help of the ST Nucleo Sensor Shield library which is compatible with the MBED API.
00006     Then we will send the measurements via USB to our PC using serial communication.
00007     We can then display the results using a terminal emulation program (e.g. Termite).
00008 
00009     At the same time the program blinks the on board LED to show alivness.
00010 
00011 
00012     GOOD LUCK!
