light connection:
VCC -> 3V3 or 5V
GND -> GND
SCL -> SCL (A5 on Arduino Uno, Leonardo, etc or 21 on Mega and Due, on esp8266 free selectable)
SDA -> SDA (A4 on Arduino Uno, Leonardo, etc or 20 on Mega and Due, on esp8266 free selectable)
ADD -> (not connected) or GND
ADD pin is used to set sensor I2C address. If it has voltage greater or equal to
0.7VCC voltage (e.g. you've connected it to VCC) the sensor address will be
0x5C. In other case (if ADD voltage less than 0.7 * VCC) the sensor address will
be 0x23 (by default).
