Digital Logic and GPIO Trainer

Project Overview

Demonstrate logic gates, debouncing, GPIO direction and truth tables.

Objectives & Learning Outcomes

Pull-ups, digital inputs/outputs, Boolean logic and test cases

Required Hardware

Arduino Uno, buttons, LEDs, 74HC logic ICs, breadboard

Suggested Build Stages

1. Review the components and create a low-voltage wiring plan.
2. Assemble the prototype and test each sensor or module individually.
3. Implement firmware, display or communications in small verified steps.
4. Integrate the modules and document operating states and failures.
5. Run validation tests and prepare demonstration documentation.

Testing & Validation

Compare all gate truth tables, debounce timing and reset states.

Suggested Deliverables

Working demonstration, wiring diagram, commented firmware, test observations, component list, project report outline and presentation outline.

Educational project concept. Verify circuit values, actual component compatibility and safe operating limits before assembly. Illustrations are representative, not exact build photographs.
