The various LCD Panel blocks are a great way to add a human touch to a ship or base by displaying useful images or text. For LCD configuration and usage, see LCD Surface Options.
Note: Some functional blocks, such as Cockpits, Programmable Blocks, Custom Turret Controllers, and Button Panels, have customizable LCD surfaces built in that work the same way as LCD Panel blocks, which are also discussed in detail under LCD Surface Options.
LCD Panels need to be built on a powered grid to work. Without power, they display an "Offline" text. While powered without having a text, image, or script set up, they display "Online".
LCD Panel blocks come in a variety of sizes from tiny to huge (see list below) and are available for large and small grid sizes. Note that LCD Panel blocks all have connections on their backs, and very few also on a second side.
All LCD Panels and LCD surfaces work with the same principle: They are capable of displaying dynamic scripts, or few inbuilt static images accompanied by editable text. Access the ship"s Control Panel Screen to configure LCD Panels or LCD surfaces; or face the LCD Panel block and press "K".
A Text Panel, despite its name, can also display images. On large grid, it is rectangular and does not fully cover the side of a 1x1x1 block. On small grid it is 1x1x1, the smallest possible LCD block in game.
On large grid, you choose the Text Panel when you need something that has rectangular dimensions that make it look like a wall-mounted TV or computer screen. If you want to display images, this one works best with the built-in posters whose names end in "H" or "V" (for horizontal or vertical rotation). On Small grid, you place these tiny display surfaces so you can see them well while seated in a cockpit or control seat, to create a custom display array of flight and status information around you.
Corner LCDs are much smaller display panels that typically hold a few lines of text. They don"t cover the block you place them on and are best suited as signage for doors, passages, or containers. They are less suitable for displaying images, even though it"s possible. If you enable the "Keep aspect ratio" option, the image will take up less than a third of the available space.
These huge Sci-Fi LCD Panels come in sizes of 5x5, 5x3, and 3x3 blocks, and can be built on large grids only. These panels are only available to build if you purchase the "Sparks of the Future" pack DLC.
They work the same as all other LCD Panels, the only difference is that they are very large. In the scenario that comes with the free "Sparks of the Future" update, they are used prominently as advertisement boards on an asteroid station.
This LCD panel can be built on large and small grids. The transparent LCD is basically a 1x1x1 framed window that displays images and text. It is part of the paid "Decorative Blocks Pack #2" DLC.
What is special about them is that if you set the background color to black, this panel becomes a transparent window with a built-in display. In contrast to other LCD Panels it has no solid backside, which makes it ideal to construct transparent cockpit HUDs, or simply as cosmetic decoration.
While configuring an LCD Panel, the GUI covers up the display in-world and you can"t see how the text or images comes out. In the UI Options, you can lower the UI Background opacity to be translucent, so you can watch what you are doing more easily.
LCD Panel blocks have only one built-in LCD Surface, but other functional blocks have several LCD surfaces built in, for example Cockpits, Programmable Blocks, Custom Turret Controllers, Button Panels, and so on. All LCD surfaces work the same way, and have the same settings as the freestanding LCD Panel blocks. In constrast to the block variants, built-in LCD surfaces are fixed to their block "as is" and you cannot choose different screen sizes or positions. The advantage of the built-in surfaces is that they do not take up extra block space.
Artificial Horizon -- Cockpit instruments that include an AGL Altimeter in the bottom right, current angular momentum in the bottom left, and Attitude Indicator (angled lines in unit degrees) in the center. Typically only used on mobile grids, not stations.
Tip: If you are looking for an option to display inventory capacity, radar view, planetary maps, hull integrity, and the like, alas these scripts are not available by default. To calculate and display such information, you need a Programmable Block. Advanced players can write custom scripts, and everyone can download community-provided scripts from the Workshop that can be configured to output info from the Programmable Block to an LCD of your choice.
Edit Text -- Click this button to enter or paste text to display. Lines don"t wrap automatically, so enter line breaks where necessary to make it fit.
Second, consider creating your custom image out of Monospace text, using Block Elements as pixels. Here is a great community app that converts any pictures into Block Element text: https://github.com/Whiplash141/Whips-Image-Converter/
You can exclude specific inventories from the item counting mechanism. This could be useful if you don"t want the autocrafting to see certain items in docked ships for example. Also, the inventory panels won"t show the items of that inventory either.
By default, new containers are assigned to be used by the script, when a container is full or no container of a specific type exists yet. Containers for tools, ammo and bottles are always assigned as one. The same applies to ingot and ore containers.
To start off, you need to build an LCD and name it "LCD Autocrafting". The script will put a list of components, that are autocraftable on the LCD. To set a new wanted amount, you simply have to edit the text on the LCD and change the number to your likings.
Autocrafting LCDA LCD with the keyword "Autocrafting" is required where you can set the wanted amount! This has multi LCD support. Just append numbers after the keyword, like: "LCD Autocrafting 1", "LCD Autocrafting 2", ..
If you want autocrafting to manage the amount of an item but you don"t want it to be shown on the autocrafting LCD, you can use the "H" modifier. The item with its current wanted amount will be moved to the custom data of your (first) autocrafting LCD and hidden from the LCD itself. The amount can be changed afterwards by editing it in the custom data. If you want to show it on the LCD again, just remove the line in the custom data.
If you want you want to hide an item from the autocrafting LCD and don"t want autocrafting to manage it, use the "I" modifier (this was done with a negative item amount before v2.8.0). The item will be moved to the custom data of your (first) autocrafting LCD and hidden from the LCD itself. If you want to show it on the LCD again, just remove the line in the custom data.
Modifiers are also combineable. "AP" for example will assemble only and prioritize. "AD" will basically just show the item on the LCD but neither assemble nor disassemble it.
If you set up your autocrafting LCD already and set all your wanted amounts, you can enable automatic disassembling in your config section (heading Autocrafting). This feature will disassemble all your excess materials automatically using all available assemblers.
Please be sure to set your wanted amounts BEFORE your enable this feature as this will disassemble all your goods imediately and turn them back into ingots. Also, manual crafting is kind of limited after enabling this because the script always tries to keep the set amount of items on the autocrafting LCD at all times.
The following topic explains, how to use LCD panels (regular and block LCDs) of my script. Whenever you add one of the following keywords to a LCD name, the keyword gets transformed to the universal [IsyLCD] keyword. In the custom data, you can then set different options about the LCD as well as the screen, the information should be shown (on blocks like cockpits, programmable blocks and so on). The custom data will look like this:
It is also possible to display informations of different scripts in one block by using this syntax (MMaster"s Automatic LCDs 2 uses the same syntax and all of my other scripts).
You can display all the main script informations like type container fill levels, managed blocks and last script actions on the main LCD. Just add the following keyword to a LCD name:
You can show the current amounts of your stored items on LCD panels. To display them, build a LCD panel, add the keyword "IIM-inventory" to its name and follow the on screen instructions:
If an inventory panel line has 0 as the max value, a single line only containing the item name and current amount is shown (no bars, percentages or max values).
Multi-panel inventory screensYou can display your inventory items over multiple screens by giving all screens the same group tag (this has to be set in the custom data of a screen after giving it the IIM-inventory tag in the name). The syntax is the following:
Note: Every panel"s name still has to contain the [IsyLCD] keyword in order to be recognized by the script (gets automatically set after giving the LCD the "IIM-inventory" tag).
Nearly every feature of the script can be temporarily enabled or disabled without the need to edit the script. These commands are sent to the script by writing them in the programmable block"s argument field and pressing run or by pulling the programmable block to any hotbar (cockpits, button panels and so on), selecting run and typing in the arguments in the popup window.
After many requests, we have decided to release our internal Replay Tool that we use to create our trailers. It allows you to record the movement and actions of multiple characters in the same world. You can use your video recording software of choice to capture these moments for cinematic purposes! It’s also super useful for epic screenshot creation. The tool allows you to be the director of your own Space Engineers film where you can carefully position and time different engineers with their own specific roles. We are extremely excited to see what the community will create with this!
Important: because it’s an internal tool, it has a very basic user interface and required advanced users to be used. We believe this is OK, because most video creators who would want to use it to create epic cinematic Space Engineers videos are advanced users.
There are now Steam trading cards to collect for Space Engineers! Collect a full set of cards to earn items that help you customize your Steam profile including backgrounds and badges.
There are fourteen new decorative blocks for people who want to buy them and support the development of Space Engineers, which are available on the Space Engineers Steam Store page. Within the package you will get following new blocks:
Beds can preserve characters’ inventory and toolbar while they"re offline and keeps them alive as long as there is oxygen available. Is considered to be the same as the Cryo Chamber Block, except oxygen is used from the environment. Space Engineers don’t work from nine to five, they work whenever they’re needed: day or night, during peace and war. But when it’s time to call it a day, every engineer looks forward to resting in these beds.
Standard and Corner Desks can be used as seats, which allow players to sit on the chair attached to it. Combine these blocks to produce various designs and sizes, creativity has no limitation. Whether designing new schematics or charting a fresh course to another world, desks are essential for any engineer looking to get some work done.
Kitchens are purely decorative. The kitchens in Space Engineers come well-equipped and include stunning visual details. Space Engineers overcome challenges everyday when they’re working on new planets or among the stars.
Planters are purely decorative, but they make outer space a bit warmer by housing life in a special glass container. Build your own garden on the space station. Planters not only help to liven up spaces, but the flora housed inside these capsules also remind many engineers of the homes they’ve left behind in order to explore the universe.
Couchescan be used as seats, so take your time to relax and take a break. You don’t need to always run, fly or work, you can enjoy your cozy room and enjoy the view. The last thing anyone would ever call a Space Engineer is ‘couch potato’, but who wouldn’t like to relax after a hard day’s work on this comfy furniture?
Armory and Armory Lockers can be used to decorate interiors and store weapons, ammunition, tools and bottles; both are small storages (400L), where you can keep your equipment. Space Engineers use lockers in order to ensure that keepsakes from home, toiletries and other items are kept safe.
Toiletscan be used as a seat. The latest and greatest interstellar lavatory technology has made many earth dwellers jealous of the facilities enjoyed by Space Engineers.
Toilet Seat that can be used as a seat and is fit for the creator of the legendary Red Ship; most engineers don’t want to get up after ‘taking care of business’.
Industrial Cockpits are used to control your ships. This industrial cockpit in both small and large grid versions will make your creations look much better. Offering unmatched visibility, the industrial cockpit enables engineers to experience stunning vistas while traversing landscapes and space.
Console blocks project blueprints for downscaled ships and stations, as well as display pictograms or customizable text. They are fantastic functional LCD panels where you can project your creations and show them to your friends. The sleek and crystal clear picture offered by this console allows Space Engineers to display designs and other important information.
Keen Software House needs to stay profitable in order to continue development and support of Space Engineers, and to take risks, to invest into experiments that may not pay off in the short term, and to develop innovative concepts.
A:Actually, even this update isn’t paid. The major part of this update (LCD screens, Replay Tool, new music tracks, smaller improvements) is free for everyone. Only the smaller and not mandatory part is paid - Decorative Pack, which you can purchase here.
A: The way we designed this is that even people who don’t purchase the Decorative Pack can play on servers with people who own the Decorative Pack. Players who don’t own the Decorative Pack won’t be able to build with these new blocks, nor interact with them, but they will be able to view them in-game.
A: To support future development of Space Engineers and other leading-edge projects we plan to work on at Keen Software House. Players kept asking us for something they could buy to support the development of Space Engineers, and the Decorative Pack is a great option for them.
A: Right after Space Engineers left early access and all hot issues were resolved. Most of the work was done by the Art team, the rest of the developers is working on other long-term updates.
A: We want more people to play Space Engineers, which means we must lower the barrier of entry. When the Space Engineers community grows, everyone benefits from this - more content on Workshop, more mods, more new ideas, more people to play with. This means that all non-mandatory features should be optional, so only those who really want them can pay for them. That’s why we decreased the price of Space Engineers, and made the Decorative Pack an optional purchase.
Looking at our upcoming plans, I can say that we are going to work on another package similar to this one. It’s not a secret that we want to bring you more things you asked for in the past, such as new skins, new weapons, new economy system etc.
The new line of 3.5” TFT displays with IPS technology is now available! Three touchscreen options are available: capacitive, resistive, or without a touchscreen.
So when I’m trying to type things on an LCD screen everything works fine in practice but we have no return button. This means we can’t tab our writing down in order to write a list of things. Like instructions for working a space station or for giving customers instructions for waiting.
You will now define your final outage duration variable. This line creates a variable named timeFormatted that holds the results of the formatElapsedTime function you just created, applied to the minutesOpened variable to correctly display the elapsed time.
This new variable takes the Impacted Customers data point and divides it by the minutesOpened variable you created earlier. Since this value will likely be a fraction, applying the Floor function on the entire calculation rounds the number to a value with two decimal points.
Once you have your final variables, timeFormatted, reliabilityIndex, and severityColor, you will return them in the expression. This allows you to reference them in the line item template as new attributes to populate the list item.
Dashboards allows you to use custom HTML to format your list items. Along with advanced formatting, this allows you to create custom visualizations that are not part of the system-defined properties. In the Line item template field, you can use the expression you just created along with HTML to format how each list item will display.
The first tag,
, determine the formatting of each piece of information included in the line item. For your list, you want to display the newly calculated time elapsed, the utility company, and the reliability impact index.

Space Engineers has been available for quite a few years now and been at least semi-popular for all of that time. With the game out that long, especially one as intricate and creative as a game like Space Engineers, it"s no wonder it"s gathered quite the modding community. There are a ton of different mods out there, from ones that just change the game aesthetically to ones that fundamentally change the way the game is played. Let"s take a look at ten of the best mods for Space Engineers out there right now:
Updated on March 14th, 2020 by Drew Ferguson:Space Engineers still seems to be going strong, and players still seem to be creating quality mods for the space sandbox game. There is always something new to do in Space Engineers because of the open-ended nature of it; as a wise man once said, "There"s always a bigger fish."
But sometimes, you simply need more options to keep things fresh and interesting. These mods add a variety of different things to the game, from new mechanics, more NPCs, a change to existing functions, and so on, while still keeping the game with the same feel that it"s always had.
There"s a lot of tedious busywork in Space Engineers. There are those that would argue that"s a strength of the game; it"s a good way to relax and spend some real time making something cool. But, some don"t have that kind of time or the desire to spend that long on a project, and for those people, there are Nanites. These Nanite"s can be programmed to do different things, from construction, repair, deconstruction, and more.
The NPC encounters in the default version of Space Engineers are a bit lacking, but the thought of not being entirely alone in the universe is pretty enticing. For those who like those cool encounters, this mod adds a bunch more of them to the game, making for a much less lonely experience. Sure, looking at the stars and pondering is fun. But so is becoming a notorious space pirate.
A bit along the lines of the last mod, this one adds cargo ships that fly around planets with atmosphere. This really makes a big difference in making the world feel pretty lively and, once again, gives ample opportunity to carve a name for yourself as an infamous space pirate. (I mean, you could be nice and let them be on their way, too, but let"s not pretend that"s what"s really going to happen, here.)
Starting off this list is a mod that might change the game more drastically than any other mod on this list. The Better Stone mod does a lot more than the name of the mod suggests; it adds a ton (seriously it"s a lot) of new ores to the game, in an attempt to make mining and ore spawning more realistic than it is in the base game. More than just adding new ores, the ores will also spawn a bit more realistically in big clumps of a lot of different ores, rather than a huge clump of one kind, mostly eliminating the need to run around for hours trying to find an infinitesimal amount of one specific ore.
Let"s face it: the base game of Space Engineers can be a bit dreary. Just about the entire HUD is the same washed out blue color, and after a few hours of staring at it, it starts to look more than a bit dull.
On the topic of adding a bit of color to Space Engineers, here"s another mod to help: the Colorful Icons mod. Instead of every single item in every inventory being that same washed-out blue as the rest of every HUD element, it shows every item the same color that it is in the game when it"s outside the inventory. This really does wonders for the hours of time you"ll be spending sifting through the inventories here.
Space Engineers animations have come a long way since it"s early access launch all those years ago, but there"s still times you"re doing something in-game and your character sort of just stands there. With the Animated Interactions mod, that problem is more or less eliminated. Even if you play in first-person, most of what you"re going to do has an animation with this mod, doing wonders to increase that all-powerful immersion.
Space Engineers holds one dark secret: the knowledge that ninety-percent of your time in game is going to be spent looking to see how many materials of what kind are needed to build an item, trying very desperately to memorize them for the short trip back to the assembler, only to realize you have no idea what you needed and need to go back. The Easy Inventory mod fixes this, grabbing all of the things need to build that item and automatically stuffing them into your inventory.
While the space in Space Engineers looks cool, it doesn"t quite look real. For those who want to make space look as realistic as possible, there"s the Space Just Got Real mod.
For those with a bit of adventurer in them, there"s the Exploration Enhancement mod. This mod adds an incredible amount to the table, with entirely new and complex systems like trading, police, military, random encounters, more (and cooler) cargo ships, more (and cooler) pirates, and custom factions. All of the things mentioned above come with unique systems that react to what you do.
Ever thoughtSpace Engineers was a little bit quiet? A bit lonely? Well, while it"s not quite the same as having a human companion, with the Ship AI Voice Basic mod, at least someone is talking! This mod adds dozens of voice lines to the game, all reacting and responding to what you do.
Everybody"s been there. A flip is switched, something doesn"t quite go as planned, and that huge space freighter that took dozens of hours to build is being torn apart by its own turrets.
But with the Smart Turrets mod, the disaster might have been avoided. This mod allows for a whole slew of new options, allowing for new targeting parameters, targeting specific blocks, the order in which it should destroy blocks, etc. For players who are into the combat in Space Engineers, this mod is a great addition.
Walking around on a planet in Space Engineers can feel like a pretty empty and meaningless experience. There"s so much land, and absolutely nothing to find. Well, picking up the Surface Occupation mod somewhat alleviates this problem! This mod adds quite a few different stations that will randomly generate on the surface of planets, ranging from defense installations to observation outposts. Most importantly, it makes the game-world feel a little less empty, making for a much more enjoyable time.
When one of these tasks is invoked, it simply prints its arguments. The order of printed arguments is the same as the order that the x appears in the argument list. If no argument is specified, it can be declared a null argument, and when the display task is invoked, it simply prints a single space character. An argument can be an expression that returns a value and a quoted string.
The first group of displaying tasks is very similar to print the function in the ANSI C language. The $write and the $display tasks work in the same way, and the only difference is that the $display task adds a new line character at the end of the output, while the $write task does not.
$strobe prints the final values of variables at the end of the current delta time-step and has a similar format like $display. A newline is automatically added to the text.
$monitor is like a task that is spawned to run in the background of the main thread, which monitors and displays value changes of its argument variables. A new $monitor task can be issued any number of times during the simulation.
If you’ve ever tried to connect an LCD display to an Arduino, you might have noticed that it consumes a lot of pins on the Arduino. Even in 4-bit mode, the Arduino still requires a total of seven connections – which is half of the Arduino’s available digital I/O pins.
The solution is to use an I2C LCD display. It consumes only two I/O pins that are not even part of the set of digital I/O pins and can be shared with other I2C devices as well.
True to their name, these LCDs are ideal for displaying only text/characters. A 16×2 character LCD, for example, has an LED backlight and can display 32 ASCII characters in two rows of 16 characters each.
At the heart of the adapter is an 8-bit I/O expander chip – PCF8574. This chip converts the I2C data from an Arduino into the parallel data required for an LCD display.
If you are using multiple devices on the same I2C bus, you may need to set a different I2C address for the LCD adapter so that it does not conflict with another I2C device.
An important point here is that several companies manufacture the same PCF8574 chip, Texas Instruments and NXP Semiconductors, to name a few. And the I2C address of your LCD depends on the chip manufacturer.
So your LCD probably has a default I2C address 0x27Hex or 0x3FHex. However it is recommended that you find out the actual I2C address of the LCD before using it.
Connecting an I2C LCD is much easier than connecting a standard LCD. You only need to connect 4 pins instead of 12. Start by connecting the VCC pin to the 5V output on the Arduino and GND to ground.
Now we are left with the pins which are used for I2C communication. Note that each Arduino board has different I2C pins that must be connected accordingly. On Arduino boards with the R3 layout, the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. They are also known as A5 (SCL) and A4 (SDA).
After wiring up the LCD you’ll need to adjust the contrast of the display. On the I2C module you will find a potentiometer that you can rotate with a small screwdriver.
Plug in the Arduino’s USB connector to power the LCD. You will see the backlight lit up. Now as you turn the knob on the potentiometer, you will start to see the first row of rectangles. If that happens, Congratulations! Your LCD is working fine.
To drive an I2C LCD you must first install a library called LiquidCrystal_I2C. This library is an enhanced version of the LiquidCrystal library that comes with your Arduino IDE.
The I2C address of your LCD depends on the manufacturer, as mentioned earlier. If your LCD has a Texas Instruments’ PCF8574 chip, its default I2C address is 0x27Hex. If your LCD has NXP Semiconductors’ PCF8574 chip, its default I2C address is 0x3FHex.
So your LCD probably has I2C address 0x27Hex or 0x3FHex. However it is recommended that you find out the actual I2C address of the LCD before using it. Luckily there’s an easy way to do this, thanks to the Nick Gammon.
But, before you proceed to upload the sketch, you need to make a small change to make it work for you. You must pass the I2C address of your LCD and the dimensions of the display to the constructor of the LiquidCrystal_I2C class. If you are using a 16×2 character LCD, pass the 16 and 2; If you’re using a 20×4 LCD, pass 20 and 4. You got the point!
In ‘setup’ we call three functions. The first function is init(). It initializes the LCD object. The second function is clear(). This clears the LCD screen and moves the cursor to the top left corner. And third, the backlight() function turns on the LCD backlight.
After that we set the cursor position to the third column of the first row by calling the function lcd.setCursor(2, 0). The cursor position specifies the location where you want the new text to be displayed on the LCD. The upper left corner is assumed to be col=0, row=0.
There are some useful functions you can use with LiquidCrystal_I2C objects. Some of them are listed below:lcd.home() function is used to position the cursor in the upper-left of the LCD without clearing the display.
lcd.scrollDisplayRight() function scrolls the contents of the display one space to the right. If you want the text to scroll continuously, you have to use this function inside a for loop.
lcd.scrollDisplayLeft() function scrolls the contents of the display one space to the left. Similar to above function, use this inside a for loop for continuous scrolling.
If you find the characters on the display dull and boring, you can create your own custom characters (glyphs) and symbols for your LCD. They are extremely useful when you want to display a character that is not part of the standard ASCII character set.
CGROM is used to store all permanent fonts that are displayed using their ASCII codes. For example, if we send 0x41 to the LCD, the letter ‘A’ will be printed on the display.
CGRAM is another memory used to store user defined characters. This RAM is limited to 64 bytes. For a 5×8 pixel based LCD, only 8 user-defined characters can be stored in CGRAM. And for 5×10 pixel based LCD only 4 user-defined characters can be stored.
After the library is included and the LCD object is created, custom character arrays are defined. The array consists of 8 bytes, each byte representing a row of a 5×8 LED matrix. In this sketch, eight custom characters have been created.
In this tutorial, we will learn about scrolling long string of text on a character LCD, which can be tricky. A character LCD module has a small amount of RAM that can store text and supports the continuity of text scrolling across an LCD display. However, this requires a careful design of the embedded program.
In this tutorial, we will flash a long string of text on a character LCD from Arduino and review the different steps and concerns that should be considered.
Displaying long textDisplaying long strings of text on a character LCD is far from straight forward. The reason for this is that the display data RAM of character LCD modules is limited. For example, the display data RAM (DDRAM) of a 16×2 character LCD can store only 80 characters. In a two-line mode, the DDRAM can only store 40 characters per line. This means any attempt to store a text string greater than 40 characters will override the other line.
If you want to display and scroll text greater than 40 characters on a line of 16×2 LCD, the only way to do so is to break the original string into parts and write those parts of the text string to the DDRAM one by one, scrolling each part of the text string.
Another concern is maintaining continuity of the text that’s scrolling through the LCD. If only 40 characters per line can be written to an LCD module at one time, then only 16 characters can be displayed on the LCD at a time. To maintain the continuity of text scrolling across the LCD, some characters from the previous text segment need to be repeated in the next text segment that’s written to the DDRAM.
For example, on a 16×2 character LCD, if the text is scrolled one character per step, 15 characters from the current text segment will need to be repeated in the next text segment that’s written to the DDRAM. For other LCD modules, one less the number of characters per line needs to be repeated in the text segments. The size of the text segment that can be written to the DDRAM at a time depends on the number of characters per line that can be stored in the DDRAM of that LCD module.
So, let’s suppose the following text string has to be scrolled on a line of character LCD: “Quick brown fox jumps over the lazy dog Quick brown fox jumps over the lazy dog Quick brown fox jumps over the lazy dog “
The above string has 120 characters. Since only 40 characters can be written to the DDRAM at one time, 15 characters must be repeated from the previous text segment to maintain the continuity of text on a 16×2 LCD.
To display and scroll the above-given text string of 120 characters on a 16×2 LCD, it’s necessary to break it into five text segments of 40-character lengths (except for the last one) — with 15 (16-1) characters repeating in each consecutive segment. This is because each line displays 16 characters at a time while scrolling one character at a time.
The text segments from 1 to 4 have to be scrolled 24 (40-16) times as 40 characters are written to the DDRAM at a time. These characters are scrolled on a 16-character line while the last text segment should be scrolled however many times is the length of the segment in characters — plus additional padding (spaces) between each repetition of the scroll.
The print() function is used to write textual data to the DDRAM of the character LCD. For scrolling a long text on a character LCD, the text can be broken up, as explained above, and each segment can be written to the DDRAM using the print() function.
It should be noted, however, that for scrolling text on the LCD, S/C, and RL bits of the “cursor or display shift,” the LCD command is set. Visit theto learn about LCD commands.
The scrollDisplayLeft() methodThis function scrolls the content from the display (the text and cursor) one space to the left. It needs no arguments. It simply scrolls the text written to the DDRAM by one space from the current DDRAM address (as in the address counter of the LCD).
The scrollDisplayRight() methodThis function scrolls the content of the display (the text and cursor) one space to the right. It needs no arguments. It simply scrolls the text written to the DDRAM by one space from the current DDRAM address (in the address counter of the LCD).
This function sets the direction of the text on a character LCD from left-to-right. It is the default direction of text. After calling this function, when the characters are written on the DDRAM of LCD, the characters will display from left to right. This function does not affect any previously displayed text. It only affects the text that’s passed to the LCD (via print or write function) after calling it.
This function sets the direction of the text on a character LCD from right-to-left. The default direction of the text is from left-to-right. After calling this function, when characters are written on the DDRAM of LCD, the characters will display from right to left. This function does not affect any previously displayed text. It only affects the text that’s passed to the LCD (via print or write function) after calling it.
The autoscroll() methodThis function serves to auto scroll the text of the LCD. The default direction of the text is from left to right. The direction of scrolling the text can be set using the leftToRight() function or the rightToLeft() function.
On calling this function, the text is scrolled from left-to-right or right-to-left by one space, according to the direction of text. Additionally, this function scrolls the text that’s written in the DDRAM. It does not alter the content of the DDRAM.
The command(), write() and send() methodsAll of the functions used to scroll the display of the character LCD use the command() method. This method is used to pass the LCD commands to the LCD module.
This method also uses another method — send() — to pass commands to the LCD. The command() method is used to pass commands to the LCD while the write() method is used to pass data to the LCD module (to write in the DDRAM).
The recipeIn this recipe, we will scroll long text of strings on a 16×2 character LCD. Two different strings will be scrolled on two lines of the 16×2 LCD.
One of the strings will scroll on the top line of the character LCD and repeatedly display, “EEWORLDONLINE.” The second string will scroll on the bottom line of the 16×2 LCD. It displays all of the websites of the EE Network with WTWH Media LLC.
Components required1. Arduino UNO x12. 16×2 character LCD x13. 10K Pot x14. 330 Ohms Resistor or any low-value resistor x15. Breadboard x16. Male-to-Male Jumper Wires or Connecting Wires
Circuit connectionsThe LCD module used in this project is JHD162A. This is a 16×2 LCD module with 5×8 character dots. The LCD module has a 16-pin interface. The LCD is interfaced with Arduino in a 4-bit mode. The pin 1 (GND) and 16 (LED) of the LCD module are connected to ground. Pin 2 (VCC) is connected to the VCC.
The pin 15 (LED+) of the LCD module is connected to the VCC via a small-value resistor. Pin 3 (VEE) is connected to the variable terminal of a pot while the fixed terminals of the pot are connected to ground and VCC.
The R/W pin is connected to ground because Arduino will only write data to the LCD module. The RS, EN, DB4, DB5, DB6, and DB7 pins of the LCD are connected to pins 13, 11, 7, 6, 5, and 4 of Arduino UNO, respectively. The breadboard is supplied to the common ground and the 5V supply rail from one of the ground pins and the 5V pin of Arduino UNO.
The goal is to display two strings on a 16×2 LCD module. One of the strings just displays the text “EEWORLDONLINE” on line 0 of the LCD. While scrolling on the display, this text must also scroll continuously on line 0. The text is repeated in a long string with two spaces between each repetition of the text.

After the third line segment, the string segments 1 to 3 begin repeating to enable the repeating text display, “EEWORLDONLINE.” All of the above three text-segments are 40-characters long and need to be scrolled 24 times (40-16) on a line of the 16×2 LCD.
All of the text segments are 40-characters long except the last one because the maximum capacity of the LCD’s DDRAM is 40 characters per line. Each subsequent text segment starts by repeating the last 15 characters of the previous text segment to ensure continuity of the scrolling text on the display.
A total of 15 characters are repeated because each line of the display has 16 characters and on scrolling by one space, the last 15 characters must match with the previous text segment whenever new data is written to the DDRAM. Each text segment is scrolled 24 times (40-16) as there are 40 characters stored on the DDRAM at one time and 16 characters are displayed on a line at a time on the LCD. The last line is scrolled according to the number of characters in it. This means it is scrolled less than 24 times.
The result is a scrolling display on 16×2 LCD that highlights EEWORLDONLINE on line 0 and all of the websites that are a part of the EE network on line 1.
Programming guideThe Arduino sketch starts importing the LiquidCrystal library. Then, an object defined by the variable “lcd” is defined of the LiquidCrystal class.
In the loop() function, the LCD display is first cleared using the clear() method, and the cursor is set at column 0 of the line 0, using the setCursor() method.
The text ” EEWORLDONLINE EEWORLDONLINE EEWORLDO” is printed using the print() method on the “lcd” object. Similarly, the text “”eeworldonline.com engineersgarage.com ” is printed at column 0 of line 1.
Next, a for loop is run in which the entire display is shifted left by using the scrollDisplayLeft() method 24 times. After scrolling the display on the LCD, a delay of 300 milliseconds each time is provided using the delay() function.
Similarly, the other text segments are displayed and scrolled. On line 0, three text segments are repeated continuously until the last trimmed text segment is displayed. On line 1, 11 text segments are displayed and scrolled. The last text segment on both lines is scrolled five times, according to the length of the text segments.
The body of the loop() function keeps repeating itself until Arduino is shutdown. Therefore, both long strings keep scrolling on lines 0 and 1 of the LCD module.
Arduino lacks support for C-style string manipulation functions. Otherwise, the sketch could be reduced to a few lines by storing the entire string to a variable and then trimming the string in each step for passing to the DDRAM of the LCD module. Even if the standard C’s string library might have been supported, the use of the string manipulation function would have increased the footprint of the embedded program.
