4.5.8. Sensors

This section is to be completed by the students of the class.

Task is to develop an object oriented class for one of the sensors. An example for such a class can be found at:

4.5.8.1. Compass

TODO: which compas sensor

The default pins are defined in variants/nodemcu/pins_arduino.h as GPIO

SDA=4 
SCL=5
D1=5 
D2=4.

You can also choose the pins yourself using the I2C constructor Wire.begin(int sda, int scl);
