Well it seems that the issue wasn"t that simple. I believe there is a problem with the actual LCD. I"ve testing the soldering and there doesn"t seem to be an issue with and shorting of pins.

While it did work for a short while using the 4 wires, I still have yet to be able to continually receive a constant working display. All the lights come on. I can get the contrast to work fine but the information doesn"t display (i.e. hello world!).

Is there a specific way of working the LCD? I am going to return this one for a new one (different brand/manufacturer). I basically plug everything into the bb and arduino and then power it up. Sometimes I"ll get the gibberish again, most times I just get a blank screen with boxes that I can manipulate using the contrast.

At the moment I cannot get anything to pop up on the screen, other then lines 1 and 3 showing the completely filled character space (the boxes when I raise the contrast to full), while lines 2 and 4 do not respond. Again, just simple code but nothing.

This is a 20x4 Arduino compatible LCD display module with high speed I2C interface. It is able to display 20x4 characters on two lines, whitecharacterson blue background.

Generally, LCD display will run out of Arduino pin resource. It needs 6 digital pins and 2 power pin for a LCD display. If you want to build a robot project, it will be a problem with Arduino UNO and LCD display.

This I2C 20x4 LCD display module is designed for Arduino microcontroller. It is using I2C communication interface, With this I2C interface, only 2 lines (I2C) are required to display the information on any Arduino based projects. It will save at least 4 digital / analog pins on Arduino. All connector are standard XH2.54 (Breadboard type). You can connect it with jumper wire directly.

This 1602 LCD module has 8 I2C address in all, from 0x20 to 0x27. You can set one according to your requirements, avoiding the confliction of I2C address. And its contrast can be adjusted manually.

This board is able to be powered by 5V or 3.3V which make it compatible with both Arduino 101 or Arduino  DUE,  intel edison 3.3V system and standard Arduino UNO/Arduino Mega 5V system.

I am very new to the Photon coming over from Arduino. I am making a RFID scan in system for a project to replace a current system. The RFID integration was super easy and I love the simplicity, the integration of the LCD is not going so well.

Using the LiquidCrystal library and the example project following their pin layout (no i2c chip) and I am not able to get it up and running. They ONLY change I have made is to set the screen size to a 20x4 vs. a 16x2. Even leaving the 16x2 doesn’t work. Screen is lighting up and 10k pot is working just fine… but only first and 3rd line are showing character placement (just boxes).

An LCD display, or liquid crystal display, is based on so-called liquid crystals, which change their polarization direction when an electrical voltage is applied. They become opaque.

In the LCD display these liquid crystals are arranged in segments and can independently change the transparency. You can find it applied in digital wristwatches, printer displays, thermometers or in cars.

There are LCD displays in different shapes and with all sorts of different segment arrangements, eg. as a pixel grid, as a seven-segment-display or as an alpha-numeric display.

In the Arduino area multi-line alphanumeric LCD displays with 16 pin connector are popular. They are often based on the HD44780 chip from Hitachi and are addressed with the Arduino library LiquidCrystal. They are relatively easy to connect and easy to program.

Such an LCD display can be addressed in 4 or 8 bit mode. In 4-bit mode you need 4, in 8-bit mode 8 data cables from just as many digital pins of the Arduino board. It is connected as shown in the diagram.

The display configuration is transferred in the setup. The two parameters represent the number of characters in a line and the number of lines. In this example, 16 characters and 2 lines:

If you want to write something to a certain position, you have to move the cursor first. Here on the first character of the second line (it is counted from 0). The example outputs the current milliseconds / 1000. So there are seconds since turning on:

There is another option to run an LCD display with even fewer pins. They have an additional controller and can be easily controlled via the I2C interface from the Arduino. (I2C is a data connection that provides control signals between various electronic components.) A look is definitely worth it.

The Arduino doesn"t have an intrinsically native display. Programmers frequently debug their software by printing stuff to a screen, or they need a human-machine-interface to show what"s happening, and even a simple text display can be quite handy.With this article we"ll install a particular kind of LCD display, and learn how to drive the LCD display using the LiquidCrystal library. This particular LCD requires wiring up a little circuit that uses a potentiometer to control brightness. While we might yearn for a simple-to-connect-display, we do learn a little electronics along the way. At the end of the day the Arduino is about encouraging us to fire up our soldering iron and making things.

The LiquidCrystal library runs on Arduino, and supports LiquidCrystal displays (LCDs) based on the Hitachi HD44780 (or a compatible) chipset. These are widely available and very inexpensive.

While the first of these is the one I used, both claim to be compatible with the HD44780 and therefore the following instructions are suitable for both.

In that video the wiring is performed on a prototyping breadboard. The display boards shown above have simple holes on a PC board to which you solder wires, whereas in the video he clearly pushes the display into holes in the breadboard.

The Arduino I purchased came in a kit with a breadboard and a bunch of jumper wires. I should have wired the display as in the video, with components on a breadboard. But this LCD doesn"t have a way to securely connect the jumper wires. That"s because the LCD display board simply has holes, and while you can stick the jumper wires in the holes they don"t stay in place. Pondering the gizmos in front of me, I decided to instead solder components to a small circuit board.

I"m afraid my soldering job wasn"t good, and the connection is a little flaky - the display flickers out if you move it around, fixed by adjusting the wires.

Simply connect it to the Arduino, then turn on the Arduino. While there is no default text displayed, some blocks and other things will show up letting you adjust the potentiometer.

Before printing text to the LCD we need to make sure the LiquidCrystal is installed. As with all other Arduino libraries, you do this via the Library Manager section of the IDE. Simply enter LiquidCrystal in the search box and it shows up as shown here. If you need to install that library, it"s done from here.

This line of code actually informs the LiquidCrystal library what Arduino pins to use in communicating with the display. Of course they match the wiring diagram.

This line in setup configures the display size. The displays shown above has 20 columns by 4 rows, while this line of code configures the display for 16 lines by 2 rows.

This looks simple doesn"t it? The LiquidCrystal library takes this and works out the graphics to show the text. The display we"ve chosen here accepts graphics commands, not text commands. Behind the scenes of this command there"s a lot going on, but we don"t have to worry about that.

Here is the loop of this Sketch, meaning that this function execute repeatedly. The setCursor command moves the text cursor to the first column (column 0) of the second line of the display (line 1). The subsequent lcd.print command takes the current time, printing it on the screen at the location of the text cursor.

This module is an Arduino compatible LCD display module with high speed I²C interface. It can display 20×4 characters (white characters on a blue background).
