print the number of seconds since reset: set up the LCD's number of columns and rows: initialise the library with the numbers of the interface pins #include & amp lt LiquidCrystal.h& amp gt In fact, the Arduino IDE includes some sample Sketches to play around with such as the following “Hello World!”, but we’ll change it to display The Geek Pub instead! The great news is that the Arduino IDE already includes an LCD character display control library built-in to use in your Sketches! So much of the work of programming a display is already done for you. Thanks to the magic of Fritzing, one of my favorite tools for drawing wiring diagrams, you can see my wiring schematic. To make things a little simpler to understand, you can reference the following pinout for a standard 16×2 LCD character display. Other than contrast, we’ll just direct wire everything else. This is because the LCD, backlight, and LCD contrast can be controlled separately for more advanced projects. You’ll see three of its pins go to ground and two get +5V power. The LCD wiring might seem a little confusing at first. This is a pretty simple wiring job, so it shouldn’t be too difficult even if its one of your first projects. The first step in getting the LCD character display working is to wire it up to the Arduino. The LCD display linked above is from Adafruit and comes with pre-soldered pins. You can get them about $4 cheaper if you don’t mind soldering. Note that most LCD character displays do not come with the pins soldered on. We may get a small commission that helps us keep making awesome content like this! QTY If you’re just getting started or just want a simple list of parts, we’ve provided a simple shopping list for you. The potentiometer is there to adjust the contrast of the screen, so you can’t skip it (though if you knew the exact contrast you wanted you could use a specific fixed resistor, making the contrast static rather than adjustable). You’ll also need a breadboard, some breadboard wires, and 10K potentiometer (pretty close will do in a pinch). You’ll of course need an Arduino and the LCD display. Getting the Arduino LCD display wiring project together relies on just a few simple parts. Whether you’re just learning about the Arduino for educational reasons or have a real world project you’d like to accomplish, getting Arduino LCD display wiring and programming under your belt is a great thing to do! Arduino LCD Display Wiring Basics Creating a game on the LCD also a fun little project. You can display information to the user, error and diagnostic codes, and even fun little animations. This is because LCD screens have so many applications in the real world.
One of the first projects many people like to do with an Arduino is wiring up an LCD display and programming it.
