Hardware & Microcontroller Integration

• Arduino Uno: Initial prototyping in C for basic button input and servo motor control.
• Particle Photon: Migrated to C++ for real-time control and networked capabilities.
• Servo Motor Actuation: Controlled door movement with precise angle positioning and smooth operation.

GPIO & Input Handling

• Real-time reading of button inputs using GPIO pins.
• Implemented debounce handling to eliminate false triggers from mechanical button noise.

System Logic & Automation

• Button press triggers the door to open or close.
• Efficient C++ logic ensures low-latency response and consistent servo actuation.
• Modular design allows future expansion (e.g., sensor-based triggers or remote control).

Embedded Systems Considerations

• Optimized microcontroller loops for low CPU overhead.
• Reliable GPIO timing and servo PWM signal generation for consistent performance.
