From all the software engineers we"ve talked to, we"ve found a common theme: no one likes to create documentation. UML diagrams can be incredibly helpful when you need to onboard employees or reference source code during implementation, but they become outdated quickly and take hours to build—unless you use a UML diagram tool like Lucidchart.

We"ve compiled templates for three types of structural UML diagrams—class, component, and object diagrams—and three types of behavioral UML diagrams—activity, sequence, and use case diagrams. Find a template to document your systems faster than ever.

The class diagram is one of the most commonly used diagrams in UML, as explained in depth in our guide on class diagrams. Software engineers and business professionals often choose class diagrams to map the structure of particular systems because they clearly display the various classes, attributes, operations, and relationships between objects.

Component diagrams in UML are very similar to class diagrams. Both component and class diagrams display the structural relationship of software systems and their elements; however, component diagrams generally simplify the interactions within more complex systems. The components that make up this type of diagram are modular parts of the system that are inherently replaceable. Diagrams are structured this way so that the components can be easily replaced when needed.

An object diagram in UML may look similar to a class diagram because it focuses on the attributes of a class diagram and how those objects relate to each other. For example, in the ATM template below, the class titles display the type of card, account, or action that the customer uses. The class attributes are all unique—in this case, the card has a specific number and PIN, the accounts and machines have their own specific numbers and amounts, and actions have specific transaction numbers.

Many project managers and engineers use sequence diagrams in UML to get a better idea of how tasks within a project will function, overlap, and move between objects or components. Create sequence diagrams to display interactions between objects and the order in which those interactions occur.

You can read our full guide on sequence diagrams for additional reference. While the examples below cover UML sequence diagrams, Lucidchart still has the shapes and features you need to model code-based sequence diagrams as well.

With a UML use case diagram, you can create a broad, high-level view of the relationship between use cases, actors involved, and systems being performed. Take a look at our use case diagram guide to learn more about the benefits of use case diagrams and the shapes involved.

Diagrams are proven to help audiences understand and retain information significantly quicker and better than text alone. Whether you’re using your diagram in the classroom, the conference room, or for IT purposes like web diagraming, it can be the tool you need to reach your audience.

With our Google Drive integration, you’ll be able to synchronize, back up, share, and access your Lucidchart diagrams without ever leaving Google Drive’s convenient interface.

We come across Liquid Crystal Display (LCD) displays everywhere around us. Computers, calculators, television sets, mobile phones, digital watches use some kind of display to display the time.

An LCD screen is an electronic display module that uses liquid crystal to produce a visible image. The 16×2 LCD display is a very basic module commonly used in DIYs and circuits. The 16×2 translates o a display 16 characters per line in 2 such lines. In this LCD each character is displayed in a 5×7 pixel matrix.

Contrast adjustment; the best way is to use a variable resistor such as a potentiometer. The output of the potentiometer is connected to this pin. Rotate the potentiometer knob forward and backwards to adjust the LCD contrast.

A 16X2 LCD has two registers, namely, command and data. The register select is used to switch from one register to other. RS=0 for command register, whereas RS=1 for data register.

Command Register: The command register stores the command instructions given to the LCD. A command is an instruction given to LCD to do a predefined task. Examples like:

Data Register: The data register stores the data to be displayed on the LCD. The data is the ASCII value of the character to be displayed on the LCD. When we send data to LCD it goes to the data register and is processed there. When RS=1, data register is selected.

Generating custom characters on LCD is not very hard. It requires the knowledge about custom generated random access memory (CG-RAM) of LCD and the LCD chip controller. Most LCDs contain Hitachi HD4478 controller.

CG-RAM address starts from 0x40 (Hexadecimal) or 64 in decimal. We can generate custom characters at these addresses. Once we generate our characters at these addresses, we can print them by just sending commands to the LCD. Character addresses and printing commands are below.

LCD modules form a very important in many Arduino based embedded system designs to improve the user interface of the system. Interfacing with Arduino gives the programmer more freedom to customise the code easily. Any cost effective Arduino board, a 16X2 character LCD display, jumper wires and a breadboard are sufficient enough to build the circuit. The interfacing of Arduino to LCD display below.

The combination of an LCD and Arduino yields several projects, the most simple one being LCD to display the LED brightness. All we need for this circuit is an LCD, Arduino, breadboard, a resistor, potentiometer, LED and some jumper cables. The circuit connections are below.

Visio is a diagraming tool that makes it easy and intuitive to create flowcharts, diagrams, org charts, floor plans, engineering designs, and more by using modern templates with the familiar Office experience. On this page, you can access some of the top templates and sample diagrams available in Visio, or request ones that you want.

Would you like to automatically create a detailed, polished Visio flowchart from an Excel workbook? You can do this by using the Data Visualizer templates. Each template has an associated Excel workbook used to convert process data into a flowchart in Visio. You can also use your own custom Excel template, map Excel data to shapes in the Create Diagram from Data wizard, and automatically create the diagram. You can even add additional columns of data in Excel that are converted to Visio shape data.

Visio also supports two-way synchronization between the Visio diagram and the Excel workbook. Not only can you create the flow chart, by editing data in Excel and refreshing the diagram from Visio, but you can also make changes to the Visio Diagram and then update the Excel data from the diagram.

A flowchart (or flow chart) is a diagram that illustrates a process, system or other sequential sets of steps. For this reason, almost all flowcharts can be considered process flowcharts (or process flow diagrams).

With Venngage’s Smart Diagrams templates and drag-and-drop flowchart maker, you can easily duplicate, add, or delete nodes. Select a Smart Template from the Venngage library and edit according to your needs.

There are numerous tools available online to customize flow charts and process map templates. The best flow chart maker is one that offers a variety of shapes, icons, and diagram options.

Venngage offers all these and much more with our flow chart templates. Easily create a variety of diagrams using our templates as a base. Auto-resize shapes and elements or swap icons with the click of a button. Designing has never been simpler.

To start, reallocate your valuable time from creating a homemade diagram and tap into FigJam’s customizable functional decomposition diagram example. Work with your team to deconstruct functions and their sub-functions, then plug them into your template’s descending rectangular boxes. Next, trace the impact of every element by connecting each box vertically. Columns differentiate between areas of the project, but ultimately, the diagram reveals how each moving part relates to the whole.

This method isn’t so different from the way we learned in our school days, whether it was the scientific management of an experiment’s process, or referring to a poster that shows the steps of gathering information to take an idea from brainstorm to final essay. When you create a workflow diagram or chart, you’re essentially executing a process to improve your final outcome.

What is a workflow chart?A workflow chart or diagram exists to visualize a process. It uses well-known symbols and shapes to identify different stages of a process, and arrows to connect them all. The end result is a picture that allows you to see how you’ll progress from start to finish.

There are a lot of terms that describe a workflow chart, including flowchart and data flow diagram. A flowchart simply leads you through the steps. It’s built on basic cause and effect. Once A happens, B will happen next, and so on. Data flow diagram (DFD) takes into account the bigger picture. It leads you through the steps, while also taking into account where things come from, where they end up, and whether or not steps will need to be repeated.

There are several types of workflow charts or diagrams, some of which allow for more detail for particularly complex projects. Here are some of the most common, with examples and templates that you can use to get started.

The following example uses a swim lane diagram to depict the process of creating a pizza, while adding another layer of organization by attributing an area of the kitchen to each “lane.”

A SIPOC specifically focuses on the inputs and outputs of a business process. When complete, it looks like a hybrid between a flowchart template and a swim lane diagram, only the lanes are always used to organize the process by supplier, input, process, output, and customer.

A fishbone diagram (also known as anIshikawa Diagram) is a visual way to look at cause and effect. Its structured, visual layout can help with brainstorming possible causes of a problem.

When conducting a fishbone analysis, teams work together to brainstorming and categorize factors contributing to a problem. Using a fishbone diagram template can help in identifying root problems rather than just symptoms. It’s especially powerful as a collaborative exercise as it directs teams to consider new, alternative causes.

Create your own fishbone analysis with this simple online fishbone diagram template. Remote or distributed teams can use the template to collaborate in real-time with ease. Simply click on the template below and get started right away or follow the five-step guide below.

Continue identifying all the root causes of all the problems. Within your team, analyze the diagram and decide on the next steps to deal with these issues.

As one of seven tools within the quality control tool chest, the fishbone diagram can help projects progress. When teams hit a roadblock and are unable to identify the cause they may need to look deeper at the underlying issues. Afishbone analysis will encourage teams to identify underlying problems they weren’t even aware of.

We’ve created a fishbone diagram example to help you understand what a completed template looks like. The example is based on finding a diagnostic error in the field of medical science.

Diagrams such as matrices, graphs, maps, and charts help people visualize information. SmartDraw has templates for over 70 different types of diagrams. Diagrams display data in a pictorial way, showing the relationship between information blocks and data sets.

A flowchart is meant to display a task or process in a sequence. Such charts are often required for making business diagrams, models showing production processes and tasks.
