Flow Diagrams
Definition
Flow Diagrams
A visual representation of actions and decisions in a sequence, showing how a system progresses toward an outcome.
Note
Flow diagrams are not limited to electronic systems. They are used in various fields, including software development, business process modeling, and project management.
Why Use a Flow Diagram?
- Helps visualize the logic of a program or circuit
- Makes it easier to debug or improve the design
- Supports communication with others (engineers, designers, programmers)
Key Components of Flow Diagrams
| Symbol Shape | Name | Purpose |
|---|---|---|
| Oval | Start/End | Indicates the beginning or end of a flow |
| Rectangle | Process | A task, operation, or activity |
| Diamond | Decision | A conditional branch with Yes/No or True/False |
| Parallelogram | Input/Output | Data being received or displayed (e.g., sensor, screen) |
| Arrow | Flowline | Shows the direction of the process or logic |
Tip
- When constructing flow diagrams, always use standardized symbols to ensure clarity and consistency.
- This makes it easier for others to understand and interpret your design.
Note
Flow diagrams are particularly useful in programmable systems, where complex logic and decision-making processes are involved.
