Wiring an LCD RGB backlight to the I2C bus

In our last example in Chapter 7, Retrieving Data from the Real World with Sensors, we worked with a multifunctional digital sensor that provided us with the temperature and relative humidity information. We worked with a breakout board that uses the I2C bus to allow the Intel Galileo Gen 2 board to communicate with the sensor. Now, we will add a breakout board with a 16x2 LCD RGB backlight to allow us to display the measured temperature and humidity values with text and numbers.

The LCD RGB backlight breakout board will also be connected to the same I2C bus to which the temperature and humidity digital sensor is connected. We can connect many slaves to the I2C bus in the Intel Galileo Gen 2 board as long ...
