. This module has a resolution of 480 x 320. The code will then take away that 40cm + another 10cm (as an overflow barrier) equalling 50cm in total . The part 162 means that the LCD has 2 lines, and can display 16 characters per line. There's a dot pitch between two characters and a space between lines, thus separating characters and lines. Connect the components as the circuit attached. Step 6: Shifting the Tank Bits. We will use just 6 digital input pins from the Arduino Board. Adding an LCD display to Arduino projects can add . The display has room to display 20 columns of characters on 4 rows which makes it perfect for displaying a large amount of text without scrolling. 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.
