Most of the sensor and switch are a single line for signal. There is some other module need more than one signal line, so we need the bus connection.
\nThe 1602LCD module have 16 pins, there are 5 power pins and 11 signal pins. To control the 1602LCD module at least 10 pins, so we need a bus to connect it to Arduino.
\nConnect the 1602LCD Brick with the 10pins cable to the BUS2 connector of Chassis. And put the power switch to \u2018On\u2019.<\/p>\n

\"\"<\/a><\/p>\n

We can use the library for Liquid Crystal to control the LCD easily. This library allows an Arduino board to control Liquid Crystal displays (LCDs) based on the Hitachi HD44780 (or a compatible) chipset, which is found on most text-based LCDs. The library works with in either 4- or 8-bit mode.<\/p>\n

Library Function:
\nLiquidCrystal()<\/strong>\u00a0 Creates a variable of type Liquid Crystal.
\nSyntax:\u00a0\u00a0 LiquidCrystal(rs, rw, enable, d4, d5, d6, d7)
\nLiquidCrystal(rs, rw, enable, d0, d1, d2, d3, d4, d5, d6, d7)<\/p>\n

clear()<\/strong>\u00a0 Clears the LCD screen and positions the cursor in the upper-left corner.<\/p>\n

home()<\/strong>\u00a0 Positions the cursor in the upper-left of the LCD. That is, use that location in outputting subsequent text to the display. To also clear the display, use the clear() function instead.<\/p>\n

setCursor()<\/strong>\u00a0\u00a0 Position the LCD cursor; that is, set the location at which subsequent text written to the LCD will be displayed.
\nSyntax:\u00a0\u00a0 lcd.setCursor(col, row)<\/p>\n

write()<\/strong>\u00a0\u00a0 Write a character to the LCD.
\nSyntax:\u00a0\u00a0 lcd.write(data)
\n\u00a0
\nprint()<\/strong>\u00a0\u00a0 Prints text to the LCD.
\nSyntax:\u00a0\u00a0\u00a0 lcd.print(data)
\nlcd.print(data, BASE) (BASE (optional): the base in which to print numbers: BIN for binary (base 2), DEC for decimal (base 10), OCT for octal (base 8), HEX for hexadecimal (base 16).)<\/p>\n
