lucadevito 0:ace8017575ea 2 LAB EXERCISE - Environmental sensors measurements
lucadevito 0:ace8017575ea 3 ----------------------------------------
lucadevito 0:ace8017575ea 4 In this exercise we will read the environmental sensors on the Nucleo sensors shield (X-NUCLEO-IKS01A1)
lucadevito 0:ace8017575ea 5 with the help of the ST Nucleo Sensor Shield library which is compatible with the MBED API.
lucadevito 0:ace8017575ea 6 Then we will send the measurements via USB to our PC using serial communication.
lucadevito 0:ace8017575ea 7 We can then display the results using a terminal emulation program (e.g. Termite).
lucadevito 0:ace8017575ea 8
lucadevito 0:ace8017575ea 9 At the same time the program blinks the on board LED to show alivness.

lucadevito 0:ace8017575ea 11
lucadevito 0:ace8017575ea 12 GOOD LUCK!
