Hello World! - How to wire an LCD display and bring it to life.īlink - Control of the block-style cursor.Ĭursor - Control of the underscore-style cursor.ĭisplay - Quickly blank the display without losing what's on it. Liquid Crystal Library - Your reference for the Liquid Crystal library. You need to connect the board to your computer and use the Arduino Software (IDE) serial monitor to communicate with it. For more circuit examples, see the Fritzing project page Code For more circuit examples, see the Fritzing project page Schematic A 220 ohm resistor is used to power the backlight of the display, usually on pin 15 and 16 of the LCD connector To wire your LCD screen to your board, connect the following pins:Īdditionally, wire a 10k pot to +5V and GND, with it's wiper (output) to LCD screens VO pin (pin3). A computer running the Arduino Software (IDE)īefore wiring the LCD screen to your Arduino 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.Pin headers to solder to the LCD display pins
LCD Screen (compatible with Hitachi HD44780 driver) To use it, upload the sketch, then open the Serial Monitor and type some characters and click Send. This tutorial specifically covers putting together the hardware, but primarily building a rudimentary 16x2 LCD GUI using the LiquidCrystal library and a simple menu system for it to display, followed by the workings of of the A4988 stepper driver and how to control it with Arduino. This example sketch accepts serial input from a host computer and displays it on the LCD. There are many of them out there, and you can usually tell them by the 16-pin interface. Compatible with Arduino UNO and Mega2560, and can be connected directly by inserting the pin into the interface without wire. The Liquid Crystal Library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver.
