Adding a display to your Arduino can serve many purposes. Since a common use for microcontrollers is reading data from sensors, a display allows you to see this data in real-time without needing to use the serial monitor within the Arduino IDE. It also allows you to give your projects a personal touch with text, images, or even interactivity through a touch screen.

Transparent Organic Light Emitting Diode (TOLED) is a type of LED that, as you can guess, has a transparent screen. It builds on the now common OLED screens found in smartphones and TVs, but with a transparent display, offers up some new possibilities for Arduino screens.

Take for example this brilliant project that makes use of TOLED displays. By stacking 10 transparent OLED screens in parallel, creator Sean Hodgins has converted a handful of 2D screens into a solid-state volumetric display. This kind of display creates an image that has 3-dimensional depth, taking us one step closer to the neon, holographic screens we imagine in the future.

Crystalfontz has a tiny monochrome (light blue) 1.51" TOLED that has 128x56 pixels. As the technology is more recent than the following displays in this list, the cost is higher too. One of these screens can be purchased for around $26, but for certain applications, it might just be worth it.

The liquid crystal display (LCD) is the most common display to find in DIY projects and home appliances alike. This is no surprise as they are simple to operate, low-powered, and incredibly cheap.

This type of display can vary in design. Some are larger, with more character spaces and rows; some come with a backlight. Most attach directly to the board through 8 or 12 connections to the Arduino pins, making them incompatible with boards with fewer pins available. In this instance, buy a screen with an I2C adapter, allowing control using only four pins.

Available for only a few dollars (or as little as a couple of dollars on AliExpress with included I2C adapter), these simple displays can be used to give real-time feedback to any project.

The screens are capable of a large variety of preset characters which cover most use cases in a variety of languages. You can control your LCD using the Liquid Crystal Library provided by Arduino. The display() and noDisplay() methods write to the LCD, as shown in the official tutorial on the Arduino website.

Are you looking for something simple to display numbers and a few basic characters? Maybe you are looking for something with that old-school arcade feel? A seven-segment display might suit your needs.

These simple boards are made up of 7 LEDs (8 if you include the dot), and work much like normal LEDs with a common Anode or Cathode connection. This allows them to take one connection to V+ (or GND for common cathode) and be controlled from the pins of your Arduino. By combining these pins in code, you can create numbers and several letters, along with more abstract designs—anything you can dream up using the segments available!

These tiny LCD screens are monochrome and have a screen size of 84 x 48 pixels, but don"t let that fool you. Coming in at around $2 on AliExpress, these displays are incredibly cheap and usually come with a backlight as standard.

For a step up in resolution and functionality, an OLED display might be what you are looking for. At first glance, these screens look similar to the 5110 screens, but they are a significant upgrade. The standard 0.96" screens are 128 x 64 monochrome, and come with a backlight as standard.

They connect to your Arduino using I2C, meaning that alongside the V+ and GND pins, only two further pins are required to communicate with the screen. With various sizes and full color options available, these displays are incredibly versatile.

For a project to get you started with OLED displays, our Electronic D20 build will teach you everything you need to know -- and you"ll end up with the ultimate geeky digital dice for your gaming sessions!

These displays can be used in the same way as the others we have mentioned so far, but their refresh rate allows for much more ambitious projects. The basic monochrome screen is available on Amazon.

Thin-film-transistor liquid-crystal displays (TFT LCDs) are in many ways another step up in quality when it comes to options for adding a screen to your Arduino. Available with or without touchscreen functionality, they also add the ability to load bitmap files from an on-board microSD card slot.

Arduino have an official guide for setting up their non-touchscreen TFT LCD screen. For a video tutorial teaching you the basics of setting up the touchscreen version, YouTuber educ8s.tv has you covered:

With the touchscreen editions of these screens costing less than $10 on AliExpress, these displays are another great choice for when you need a nice-looking display for your project.

The reason these displays look so good is down to the way they function. Each "pixel" contains charged particles between two electrodes. By switching the charge of each electrode, you can influence the negatively charged black particles to swap places with the positively charged white particles.

This is what gives e-paper such a natural feel. As a bonus, once the ink is moved to its location, it uses no power to keep it there. This makes these displays naturally low-power to operate.

This article has covered most options available for Arduino displays, though there are definitely more weird and wonderful ways to add feedback to your DIY devices.

Now that you have an idea of what is out there, why not incorporate a screen into your DIY smart home setup? If retro gaming is more your thing, why not create some retro games on Arduino?

This module works with at least the LiquidCrystal I2C and LiquidCrystal_PCF8574 libraries available in the Arduino library manager. Address 0x3F worked for me since the A0, A1, and A2 jumpers are not shorted.

Recently purchased unit has a different address than the same part number purchased a year ago. It seems that if the small board is marked MH, the address is not going to be 0x27 or 0x20 but 0x3F. With that change of address, this display works and looks great.

Google for LCM1602 and you will find many pages that mention the board - including the pinouts stated above and sample programs using the Arduino library.

Heres the scoop. The library that works with this chip set is available at this link. http://www.play-zone.ch/en/fileuploader/download/download/?d=0&file=custom%2Fupload%2FFile-1345667375.zip

I liked the idea of the 4-wire interface, but I was disappointed that no documentation was available for this part. However after a night of hacking I got it to work with my Arduino Uno. I thought Id pass along the following information to spare others the trouble.

On the software side, you have to download and install a new LiquidCrystal_I2C library for Arduino, which has the capability to talk to the LCD display over the I2C bus. Heres a link to the library. Follow the example code for the DFRobot board, which turns out to have the same configuration as this LCD, and it should fire right up for you. The LCD has white characters on a backlit blue background, and looked great.

Before you learn how to connect your display to Arduino, it’s worth to think about what exact task it’s going to perform, to choose the right type and model of display. Commonly used with Arduino are 2×16 alphanumeric LCD displays (capable of displaying 2 lines of 16 characters each) with green or blue backlight.

In the offer of electronics shops you will often find e-paper displays as well – their main advantage over other screens is much lower energy consumption (due to the type of technology) and a unique image that looks literally as if the content was written on paper. The biggest disadvantage of this solution is of course the relatively high price per unit.

Shops often also offer larger versions of LCD displays, 8-segment displays, touch screens and many other solutions. The choice should be made based on the needs – for example, if the project is commercial and the device will be used in sunlight, and low price is not a priority – no backlighting will be an advantage and an e-paper display will work well for this. In a project where the device will only need to display a single number – an 8-segment display will work well. Nevertheless, the most popular choice remains the 2×16 LCD, which works well for most projects and is particularly popular with electronics beginners and students.

Due to its high popularity and usefulness, below we will describe how to connect a 2×16 LCD display. This type of equipment is usually sold as a display on a laminated PCB – some products have the I2C converter soldered in, but some models do not have it. In this case such a converter must also be prepared to realise the project. To complete the whole task it will be practical to use a contact board, thanks to which you will be able to reuse each of the used elements many times – also in other projects. Prepare also a set of connection wires (with male and female plugs on their ends) and

The first step is to solder a female goldpin to GPIO pins on Arduino board. Thanks to this, you will be able to connect any device in any configuration and use for example dedicated frontends (e.g. with male goldpins soldered on). If the I2C converter does not have male leads, a goldpin strip should be soldered there as well. Both components should be connected by correct positioning on the contact board. Converter should have 4 pins on output – it will be power supply (VCC), ground (GND) and SDA and SCL.

Before connecting the power supply make sure exactly what voltage your display requires – it will be 3.3 V or 5 V. Based on this information, connect the VCC pin from your converter to the corresponding voltage on your Arduino board. Of course, you can power the display with an external power supply, but this will only make sense if you connect more components to the board. The GND pin should be connected to the GND pin on the Arduino, and the SDA and SCL pins to the analog inputs on the board.

Oczywiście sposobów podłączania wyświetlacza jest bardzo wiele – te różnią się między sobą przede wszystkim w zależności od wyświetlaczy, ale także w zależności od przyzwyczajeń elektronika oraz od zadania jakie wyświetlacz ma spełniać. Nawet wśród najprostszych wyświetlaczy LCD 2×16 różnice między modelami mogą być stosunkowo duże, dlategoza każdym razem zapoznajmy się z dokumentacją techniczną, nawet jeszcze przed jego kupnem, aby uniknąć niemiłego zaskoczenia, kiedy staniemy przed problemem z podłączeniem lub przedwczesną diagnozą o uszkodzeniu sprzętu.

In this Instructables lesson, displaying texts and featuring them on a 16 by 2 LCD using Arduino is demonstrated. Let"s get started and I hope you enjoy!

Arduino is a device that is widely used by students for various robotics projects and sensors to detect heart-rate, temperature, air pressure ... Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board micro controllers and micro controller kits for building digital devices and interactive objects that can sense and control both physically and digitally. Basically Arduino is capable to store codes inserted from Arduino IDE using C and C++ coding languages from a computer to manipulate the functions that are assigned for the device to do. LCD (Liquid Crystal Display) screen is an electronic display module and find a wide range of applications. A 16x2 LCD display is very basic module and is very commonly used in various devices and circuits. A 16x2 LCD means it can display 16 characters per line and there are 2 such lines. The LCD has 16 pins. Starting from left to right, the first pin is GND (ground). The second pin is the VCC (5 volts) pin which is connected to the Arduino board. The third pin is the Vo (display contrast) pin which can be connected to a potentiometer to adjust the display contrast. Fourth pin is the RS (register select) pin used for selecting the commands/data sent to the LCD using methods defined in the Arduino Liquid Crystal packages. Fifth one is the R/W (read/write) pin which selects the mode whether we read or write on the LCD. Sixth pin is the E (enable) pin which enables writings to the registers. The next 8 pins are data pins D0 to D7 that registers are written in using binary numbers according to the ASCII Table. The fifteenth pin is the A (anode) , and the last one is K (cathode).

The IDE Now that we have a little undrestanding of what Arduino and the LCD are, let"s jump ahead into the Arduino IDE and install that on our computer. Arduino IDE can be downloaded from Or from the windows store on windows 8. The IDE is the place where coding takes place. Here, the codes are written in C and C++. After compiling the code and troubleshooting the mistakes, the complied code is sent to the Arduino Board using the USB 2 cable. After installing the IDE we implement the Liquid Crystal package as shown below. Liquid Crystal Package implementation... Installing LiquidCrystal package opens our access to use the methods and implementations defined in the specific package regarding to the LCD on our IDE to be compiled and stored into the Arduino board. After package installation, the setup and loop are written in the IDE. Follow the above and copy the parameters to make a connection between the board and the LCD.

Compiling and Storing the Code into the Arduino For the last step, connect the Arduino to the computer using a USB-2 cable. compile the code and select the Arduino UNO on the IDE and store the code into the Arduino by clicking on the horizontal arrow on the top left corner of the IDE.

The note "Arduino" should be appearing on your LCD. Congratulations !!! You have made your first text on the LCD... Now if you want to go the extra mile, www.arduino.cc has all the methods and explanations that can be used to use on your text for further design and change, move, personalize your own text. Above are some of the example codes found in the website. Try them yourself.

In this Arduino tutorial we will learn how to connect and use an LCD (Liquid Crystal Display)with Arduino. LCD displays like these are very popular and broadly used in many electronics projects because they are great for displaying simple information, like sensors data, while being very affordable.

You can watch the following video or read the written tutorial below. It includes everything you need to know about using an LCD character display with Arduino, such as, LCD pinout, wiring diagram and several example codes.

An LCD character display is a unique type of display that can only output individual ASCII characters with fixed size. Using these individual characters then we can form a text.

If we take a closer look at the display we can notice that there are small rectangular areas composed of 5×8 pixels grid. Each pixel can light up individually, and so we can generate characters within each grid.

The number of the rectangular areas define the size of the LCD. The most popular LCD is the 16×2 LCD, which has two rows with 16 rectangular areas or characters. Of course, there are other sizes like 16×1, 16×4, 20×4 and so on, but they all work on the same principle. Also, these LCDs can have different background and text color.

It has 16 pins and the first one from left to right is the Groundpin. The second pin is the VCCwhich we connect the 5 volts pin on the Arduino Board. Next is the Vo pin on which we can attach a potentiometer for controlling the contrast of the display.

Next, The RSpin or register select pin is used for selecting whether we will send commands or data to the LCD. For example if the RS pin is set on low state or zero volts, then we are sending commands to the LCD like: set the cursor to a specific location, clear the display, turn off the display and so on. And when RS pin is set on High state or 5 volts we are sending data or characters to the LCD.

Next comes the R/W pin which selects the mode whether we will read or write to the LCD. Here the write mode is obvious and it is used for writing or sending commands and data to the LCD. The read mode is used by the LCD itself when executing the program which we don’t have a need to discuss about it in this tutorial.

After all we don’t have to worry much about how the LCD works, as the Liquid Crystal Library takes care for almost everything. From the Arduino’s official website you can find and see the functions of the library which enable easy use of the LCD. We can use the Library in 4 or 8 bit mode. In this tutorial we will use it in 4 bit mode, or we will just use 4 of the 8 data pins.

We will use just 6 digital input pins from the Arduino Board. The LCD’s registers from D4 to D7 will be connected to Arduino’s digital pins from 4 to 7. The Enable pin will be connected to pin number 2 and the RS pin will be connected to pin number 1. The R/W pin will be connected to Ground and theVo pin will be connected to the potentiometer middle pin.

We can adjust the contrast of the LCD by adjusting the voltage input at the Vo pin. We are using a potentiometer because in that way we can easily fine tune the contrast, by adjusting input voltage from 0 to 5V.

Yes, in case we don’t have a potentiometer, we can still adjust the LCD contrast by using a voltage divider made out of two resistors. Using the voltage divider we need to set the voltage value between 0 and 5V in order to get a good contrast on the display. I found that voltage of around 1V worked worked great for my LCD. I used 1K and 220 ohm resistor to get a good contrast.

There’s also another way of adjusting the LCD contrast, and that’s by supplying a PWM signal from the Arduino to the Vo pin of the LCD. We can connect the Vo pin to any Arduino PWM capable pin, and in the setup section, we can use the following line of code:

It will generate PWM signal at pin D11, with value of 100 out of 255, which translated into voltage from 0 to 5V, it will be around 2V input at the Vo LCD pin.

First thing we need to do is it insert the Liquid Crystal Library. We can do that like this: Sketch > Include Library > Liquid Crystal. Then we have to create an LC object. The parameters of this object should be the numbers of the Digital Input pins of the Arduino Board respectively to the LCD’s pins as follow: (RS, Enable, D4, D5, D6, D7). In the setup we have to initialize the interface to the LCD and specify the dimensions of the display using the begin()function.

The cursor() function is used for displaying underscore cursor and the noCursor() function for turning off. Using the clear() function we can clear the LCD screen.

In case we have a text with length greater than 16 characters, we can scroll the text using the scrollDisplayLeft() orscrollDisplayRight() function from the LiquidCrystal library.

We can choose whether the text will scroll left or right, using the scrollDisplayLeft() orscrollDisplayRight() functions. With the delay() function we can set the scrolling speed.

So, we have covered pretty much everything we need to know about using an LCD with Arduino. These LCD Character displays are really handy for displaying information for many electronics project. In the examples above I used 16×2 LCD, but the same working principle applies for any other size of these character displays.

I hope you enjoyed this tutorial and learned something new. Feel free to ask any question in the comments section below and don’t forget to check out my full collection of 30+ Arduino Projects.

We realize a change is not always welcomed but we feel it"s the best way to move forward. The new Workshop4 IDE supports 4 development environments, to cater for different user requirements and skill levels and the Serial environment you"ve mentioned is one of them. The Serial environment is basically a 4DGL application that uses a very simple protocol and makes the display act as a slave and it works well when the host and the display are in close proximity, i.e. both on the same application PCB or the distance of the host is within a foot or two from the display. In most cases this works real well as long as the transmission path is free of external noise. There are many high end commercial products designed by many thousands of customers using just the serial platform. If the environment is noisy or the distance between the display and the host is far apart, then why not use the Designer environment and roll out your own top notch serial protocol with many different levels of error checking? Many customers also employ this method. A good outcome for any application always starts by proper understanding of what"s required and a good feasibility study of all the factors involved. You mention you"ve used many of our displays (thank you for your support), but have you tried seeking help from our very helpful team of tech support engineers? If not, please do so, I"m sure you"ll find they"ll be able to resolve most of your problems.

Edit: I have just been informed that a user reported a crashing problem on Friday the 22nd of February, he was supplied with a Fix on Saturday the 23rd and Workshop was shipping with the fix integrated on Monday the 25th. If you are that user we apologize for any inconvenience. This problem was only limited to the Goldelox based displays and not on the Picaso.

This LCD Display Shield gives you a nicely mounted 1602 LCD Display snaps right on top of your Arduino UNO. With onboard buttons for easy navigation including up, down, left, right, select and reset, using your Arduino away from a computer was never easier. Use this shield to display values read in by your Arduino, display options for user inputs, choose between different programs you can run on your Arduino, etc. With a Power LED onboard and a nice blue backlit display, you"ll be able to use your Arduino"s LCD Display Shield day or night!

This shield is compatible with the "LiquidCrystal" library that is bundled with the Arduino software. Just edit the "LiquidCrystal" library"s default mapping from the LCD pins to Arduino pins to the ones for this specific shield by copying what"s shown below. Here is an example of the proper way to instantiate the LiquidCrystal class for this shield:

An LCD (Liquid Crystal Display) is a great way to display information in our Arduino Uno controller. We will be wiring and programming an alphanumeric, two rows with 16 characters on each row. The display has an LED (Light Emitting Diode) backlight with adjustable contrast.

This white and blue LCD will display “Hello World!” on the top line and temperature on the bottom line. The thermistor temperature circuit created last time will be displayed in both Celsius and Fahrenheit degrees. Let’s get started.

When you look at an LCD display, it is made up of a series of dots or pixels. Each of these pixels is a liquid crystal. If electricity flows through the liquid crystal it will change its structure and be more rigid. This rigidity will look darker than if no electricity is applied. If we use a light behind this LCD then the backlight will make the pixels more pronounced. So electricity on the pixel will block the light and no electricity will allow the light through. This contrast is what we see using an LCD display.

The LiquidCrystal.zip file came on the disk with the Arduino UNO R3 super starter kit. It can also be downloaded from the link below with the program. Select this library and then select open. This will add the library to the Arduino IDE (Integrated Development Environment).

This first part will set up the library and declare the variables for the LCD display unit. Using the Steinhart-Hart Equation we declare our variables and set the coefficients for the equation.

The LCD is set up with 16 characters and 2 lines. The cursor for the LCD display is set for the first character on the first line by default. We then print the message “ Hello, World!”.

The program will calculate the temperature in Celsius (T) and in Fahrenheit (TF). The LCD cursor is then set to the second row and column 0. We can then print our temperatures and units of measure.

You will see the ‘Hello World!’ and the current temperature in two units of measure displayed on the LCD. Hold the thermistor between your fingers to see how rapidly the temperature can be read.
