Introduction
A flowchart is a diagram that represents a process or system, and it can be used to model a computer program or algorithm.
Here are some common flowchart symbols:
- Rectangle: Represents the start and end points of a process or system.
- Diamond: Represents a decision point. It is used to indicate a branching point in the flowchart, where the flow of the process or system can go in different directions based on a specific condition or decision.
- Arrow: Connects the different steps in the flowchart, showing the flow of the process or system.
- Oval: Represents the beginning or end of a process.
- Parallelogram: Represents an input or output.
- Cloud: Represent external entities such as a database, a webservice, etc.
- Terminator: Represent the start and end point of a sub-process
- Process: Represent the process steps in a flowchart
- Document : Represent input and output documents
- Data: Represent data storage and retrieval

In this project, we will construct a functional flow chart using cardboard, colored paper, LED lights, and a 9V battery.
This interactive model will demonstrate the flow of information or processes in a visual and dynamic way. The LED lights will represent key points or decision nodes in the flow chart.
Let’s proceed with building this educational and visually engaging project!
Materials Needed:
- Cardboard sheets
- Colored paper or construction paper
- LED lights (with resistors)
- 9V battery
- Battery clip with connector
- Glue or adhesive tape
- Scissors
- Markers or pens
- Craft knife (optional, for precise cutting)
- Copper wires
Building the Flow Chart Working Model:
1. Creating the Flow Chart Structure:
Step 1: Base Structure
- Cut out a large rectangular piece of cardboard to serve as the base of the flow chart. This will provide stability and support for the model.
Step 2: Flow Chart Elements
- Design and cut out various shapes (rectangles, diamonds, ovals, etc.) from colored paper to represent the different elements of the flow chart (processes, decisions, start/end points, etc.).
2. Integrating LED Lights:
Step 3: Planning LED Placement
- Determine which points in the flow chart will be represented by LED lights. These are typically decision points or key steps in the process.
Step 4: Preparing LED Connections
- Attach resistors to the positive (longer leg) of each LED. This is necessary to limit the current and protect the LED.
Step 5: Creating LED Housings
- Cut small holes in the flow chart elements where the LEDs will be placed. The LED should fit snugly in these holes.
Step 6: Wiring the LEDs
- Connect the positive leg of each LED to the positive terminal of the battery clip and the negative leg to the negative terminal. Use copper wires for these connections.
3. Battery Integration:
Step 7: Attaching the Battery
- Securely attach the battery to the base of the flow chart using adhesive tape or glue. Position it in a way that allows easy access to the battery clip.
Step 8: Connecting Battery Clip
- Connect the battery clip to the battery. Ensure the positive and negative terminals are correctly aligned.
4. Final Touches and Testing:
Step 9: Labeling and Detailing
- Use markers or colored paper to label the elements of the flow chart and add any additional details or explanations.
Step 10: Testing the Model
- Turn on the battery and observe the LED lights. They should illuminate at the designated decision points, demonstrating the flow of the process.
