Description The 16x2 Alphanumeric LCD Display Module is equally popular among hobbyists and professionals for its affordable price and easy to use nature. As the name suggests the 16x2 Alphanumeric LCD can show 16 Columns and 2 Rows therefore a total of (16x2) 32 characters can be displayed. Each character can either be an alphabet or number or even a custom character. This particular LCD gas a green backlight, you can also get a Blue Backlight LCD to make your projects stand our and visually appealing, apart from the backlight color both the LCD have the same specifications hence they can share the same circuit and code. If your projects require more characters to be displayed you can check the 20x4 Graphical LCD which has 20 Columns and 4 Rows and hence can display up to 80 characters.Specifications of 16x2 LCD Display Module:Operating Voltage: 4.7V to 5.3VOperating Current 1mA (without backlight)Can display (16x2) 32 Alphanumeric CharactersCustom Characters SupportWorks in both 8-bit and 4-bit ModeThe 16x2 LCD pinout diagram is shown below. As you can see the module has (from right) two power pins Vss and Vcc to power the LCD. Typically Vss should be connected to ground and Vcc to 5V, but the LCD can also operate from voltage between 4.7V to 5.3V. Next, we have the control pins namely Contrast (VEE), Register Select (RS), Read/Write (R/W) and Enable (E). The Contrast pin is used to set the contrast (visibility) of the characters, normally it is connected to a 10k potentiometer so that the contrast can be adjusted. The Read/Write pin will be grounded in most cases because we will only be writing characters to the LCD and not read anything from it. The Register Select (RS) and Enable pin (E) pin are the control pins of the LCD and will be connected to the digital pins GPIO pins of the microcontroller. These pins are used to instruct the LCD where place a character when to clear it etc.From DB0 to DB7 we have our eight Data Pins which are used to send information about the characters that have to be displayed on the LCD. The LCD can operate in two different modes, in the 4-bit Mode only pins DB4 to DB7 will be used and the pins DB0 to DB3 will be left idle. In 8-bit Mode, all the eight-pin DB0 to DB7 will be used. Most commonly the Other two act like a clock to notify to the shift-register when a bit is ready to be shifted (shift-out) or the microcontroller is ready to acquire a new bit for reading (shift-in).Another important aspect is the name of the component: register. In the assembler language a register is usually a place where a series of bits are stored for special purpose. In fact, the shift-registers not only are able to shift in one direction a certain number of bits but the bit status of every pin is persistent until another byte has not been completely sent (or received). This is perfect for us, as we need to write bytes to the LCD device managing a timing series of steps (e.g. writing a new character, moving the cursor, etc.)Alphanumeric LCD, the controlled deviceAt this point, the LCD Device will be connected with the 8-bits of the shift register (you can see the schematic and the circuit layout for the circuitry details).So, what happens when we send a set of data to the LCD Device?Our resulting sketch will be almost simple.The most inspiring source to make this project comes from a blog post by Chris Parish proposing a similar circuit in 2010. Chris also provided a first modified version of the standard Arduino LCD Library supporting the shift register features. In 2010 Arduino libraries to manage shift registers were based on the 74LS164 component.This arduinoshiftreglcd distributed on Google code was the only reference trying to solve the problem but included some bugs in the data timing and was not working properly.The very valuable work by Chris consisted in modifying the 2010 version of the LiquidCrystal library distributed with the Arduino IDE (it was not supporting the shift register at all) and thanks to his work, in January 2010 the ShiftLCD Arduino library was born.We suggest to download the ShiftLCD library from the link provided by this article. This version of the library implements the original Chris Parish ShiftLCD library with a couple of patches granting the compatibility with the most recent Arduino IDEs.A last note about the circuitIn the mentioned circuit implemented in 2010 by Chris Parish, you can find also the use of a high impedance MOSFET to control the LCD backlight. We have removed this component from our circuit because it proved useless with the cheap LCD devices working fine with or without backlight support. Note that the devices without the backlight support cost about the half compared to those with it, anyway offering a good visibility.The complete circuit kit, including the alphanumeric LCD ready to use can be found on the Balearic Dynamics area. Use code ELEKTRO1008 to get the discount!Next…In the second part of this article we will consider the usage of this tool with some software developed to simplify and shorten the sketches with the LCD device as part of our Arduino architecture.

ALPHANUMERIC LCD - eclub.iitk.ac.in

One of the limitations of the small 8 bit microcontrollers like the Atmel ATMega family adopted by the Arduino board, is the reduced number of I/O ports. Among the main advantages of these microcontrollers: they are cheap, robust and simple to program. Therefore, also Arduino or one of its clones are cheap as well.Microcontrollers in industrial applications are frequently used to manage almost simple circuits dedicated to a single task. We might think that an AVR microcontroller – e.g. the ATMega328p adopted by the Arduino UNO boards – has the sufficient number of pins to manage an alphanumeric LCD. In a complex industrial machine architecture that is more than sufficient.Thanks to the tons of Arduino users worldwide, we already know that the same ATMega328 microcontroller can do more than few basic functions. So why not many of them together?In this first article we will propose to explore the power of the Arduino board with experiments, including circuitry and software, moving further to a high-level activity than a simple demonstration. Guys, with a little effort and few $$$ of components Arduino is the ideal tool to solve a lot of problems whereas other alternative solutions may be more expansive.The Alphanumeric LCD for Arduino will be our first circuit: using only one component, and of course the LCD, we can povide our Arduino board with at least a 16×2 alphanumeric LCD display that we will use in all our future applications. This project consumes only three I/O pins, no matter what we decide to use, connected to a Shift Register. I have experienced that an alphanumeric LCD added to Arduino as a stable add-on devices is very useful during the debug phase of the sketches and gives much more options to our projects. Especially in case of unavailability of the Arduino USB port connected to the PC.The magic of the shift registerThe shift register is an easy-to-manage component. We will dedicate a series of articles illustrating applications giving us the opportunity to develop circuits using one or more shift register saving a lot of I/O pins on our Arduino board.Therefore you should expect that the software part (that is, the Arduino “Sketch”, more properly named firmware) covered extensively in the second part of this article, should be a bit complex. But the result is fascinating.We should use a cheap parallel shift-out registers (it costs, depending on the country, a variable price around half dollar): the 74HC595As a matter of fact there are two types of shift registers: shift-in (don’t worry, in future we will use this too) and shift-out parallel registers.shift-in means that all the 8 bits (corresponding to 8 pins) can be set together and serially read from the input data pin.shift-out is the opposite. We can send 8 bits serially to the output data pin shifted to the parallel 8-bits of the output pins.Regardless of the type of shift-register we are using, we need only three pins in our microcontroller. One pin is used for the serial data and the Dot matrix LCD screens and segment LCD screens are two different types of LCD (liquid crystal display) technologies used in electronic devices. Here’s a we will discuss their differences from different aspects.Display Method:Dot Matrix LCD: Dot matrix LCD screens are capable of displaying alphanumeric characters, symbols, and graphical content by arranging a matrix of tiny dots. Each dot, known as a pixel, can be individually controlled to create different patterns and images.Segment LCD: Segment LCD screens display characters, symbols, or numbers by dividing the screen into different segments. Each segment represents a specific part of a character or symbol, such as lines, curves, or dots.Resolution:Dot Matrix LCD: Since dot matrix LCD screens use a matrix of individual pixels, they offer higher resolution and can display more detailed graphics and text.Segment LCD: Segment LCD screens have lower resolution compared to dot matrix LCD screens. They are primarily used for displaying simple characters or symbols, such as numbers or basic icons.Flexibility:Dot Matrix LCD: Dot matrix LCD screens are more flexible in terms of content and layout. They can display various fonts, sizes, and graphical elements. This flexibility allows for more complex user interfaces and graphics.Segment LCD: Segment LCD screens have predefined segments, limiting the display to specific characters or symbols. They are suitable for applications that require simple and standardized information, such as digital watches or calculators.Cost:Dot Matrix LCD: Due to their higher resolution and increased flexibility, dot matrix LCD screens are generally more expensive to produce compared to segment LCD screens.Segment LCD: Segment LCD screens are relatively simpler in design and have fewer components, making them more cost-effective.Power Consumption:Dot Matrix LCD: Dot matrix LCD screens typically require more power to operate due to their higher resolution and the need to control individual pixels.Segment LCD: Segment LCD screens consume less power compared to dot matrix LCD screens, as they have fewer segments to control.Overall, dot matrix LCD screens offer higher resolution, greater flexibility, and the ability to display more complex graphics. On the other hand, segment LCD screens are simpler, cost-effective, and suitable for applications that require basic character or symbol display.
