And finally, connect the 3.3V of Arduino to the A of LCD which is the anode of backlight LED.Ĭonst int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2.

Then connect the digital pin 2 of Arduino to the D7 of LCD module.

Then connect the digital pin 3 of Arduino to the D6 of LCD module.

Then connect the digital pin 4 of Arduino to the D5 of LCD module.

Then connect the digital pin 5 of Arduino to the D4 of LCD module.

Then connect the digital pin 11 of Arduino to the E of LCD module.

Then connect the digital pin 12 of Arduino to the RS of LCD module.

Then connect the 5V of Arduino to the VDD of the LCD module.

Then connect K, which is the ground of backlight LED also to the ground.

Then connect RW to the ground for selecting write mode.

The same code and circuit will work for all Arduino and compatible boards.Ĭonnect the circuit as shown in the below diagram. In the first method, we are interfacing the LCD1602 with Arduino using the data pins of the LCD module. They are responsible for the parallel data transfer. Read Write Select pin 0: Write mode 1: Read mode Register Select 0: Instruction Register 1: Data Register Some other sizes are,Ĭontrast adjustment 0v: Max contrast 5v: Min contrast the most commonly used one is LCD1602 which can display 16 characters in each line, which is a total of 32 characters. LCD modules are coming in different colors and sizes with a different number of displayable characters. Wire Library – Will available in Arduino IDE by default.LiquidCrystal I2C Library – Download – For the second method.LiquidCrystal Library – Will available in Arduino IDE by default – For the first method.In this getting started with LCD module tutorial we are going to learn about two different ways of interfacing an LCD module with popular development boards like Arduino Nano, Arduino Uno, Arduino Mega, Arduino Leonardo.
