  SerLCD Library - Hello World
  Gaston Williams - August 29, 2018

  This sketch prints "Hello World!" to the LCD
  and shows the time over I2C using the Qwiic system.

  The circuit:
   SparkFun RGB OpenLCD Serial display connected through
   a Sparkfun Qwiic adpater to an Ardruino with a
   Qwiic shield or a Sparkfun Blackboard with Qwiic built in.

  The Qwiic adapter should be attached to the display as follows:
  Display	/ Qwiic Cable Color
 	GND	/	Black
 	RAW	/	Red
 	SDA	/	Blue
 	SCL	/	Yellow

  Note: If you connect directly to a 5V Arduino instead, you *MUST* use

how do you do with only red board and the LCD screen, if that was the only option?

what about for the air quality sensor combo?

we were hoping to get this to work as well and then maybe combine this with the LCD to let the LCD display the air quality

I suggest reading the hookup guides for all boards. They can be found on the product pages.
