Arduino IDE, Click to Download Arduino IDE from Arduino®ĭownload DFRobot LCD Library How to install Libraries in Arduino IDE /*!.Gravity: I2C LCD1602 Arduino LCD Display Module. Step-By-Step LCD Wiring (4 Bit Mode) and Programming Examples for Arduino: This instructable will guide a user step-by-step in wiring and programming a Hitachi HD44780 (or a compatible) chipset LCD.a couple of things first, when you switch power on do you get a black bar across one line of the lcd but not the other line, if yes, the lcd's not initialised, if no black bar. It aims to maintain compatibility with the Arduino LiquidCrystal library (version 0017 onwards), though some features of LiquidCrystal are ommited and additonal features are provided. well the lcd pin define looks ok for that pinout, i would say drop the 4-bit library and just go with the liquidcrystal library that comes with the Arduino IDE, it works.

Dimension: 87.0*32.0*13.0mm/3.43*1.26*0.51inįollow the pin description to connect the hardware, then download the sample code to UNO.

This kind of module has the blue screen, the green screen, the gray screen. The optimization of function and the appearance brings you the different experience. This module does not need to adjust the contrast, retain the backlight controllable function, simultaneously compatible with 3.3V and 5V voltage. Extra buttons control connects on A0 arduino pin, can use it control the LCD, analog value read on this pin. For the demo code, please change control pin to Pin 8 and 9, 4 bits data pins to D4-D7 for module Pin4-7. Uses HD44780 1602 LCD, Uses 4 Bit Arduino LCD Library LiquidCrystal. LCD1602 module is a product of the DFRobot Gravity IIC series, which has been greatly optimized for its original LCD1602 appearance. This is a 16×2 LCD Keypad module for Arduino board. Referring to the LCD16020, I believe that everyone is not unfamiliar the square shape, green color, a row of 2.54 pin header.
