Development Plan

1. Define project requirements and technical constraints.
2. Prepare architecture, flowcharts, and component or module list.
3. Implement the core feature in small verifiable stages.
4. Test errors, edge cases, and recovery behavior.
5. Document results and prepare the demonstration and viva.

Testing Checklist

• Check normal operation and expected output.
• Test invalid input, disconnections, and relevant fault cases.
• Record measurements or screenshots as appropriate.
• Document limitations, security, and operating conditions.

Deliverables

Architecture or circuit diagram, annotated code, screenshots or measurements, test report, documentation outline, and demonstration.
