The four most significant bits must be written first, followed by the four least significant bits LCD display module with blue blacklight. Before wiring the LCD screen to your Arduino or Genuino board we suggest to solder a pin header strip to the 14 or 16 pin count connector of the LCD screen, as you can see in the image above.
These hs4470 have to be written to the device each time it is switched on, as they are stored in volatile memory.
