🛰 Background Theory

🔋 Embedded Systems Fundamentals

An embedded system is a dedicated computing system designed to perform specific control functions within larger mechanical or electrical systems. Unlike general-purpose computers, embedded systems operate with:

• Limited processing power

• Real-time constraints

• Dedicated input/output interfaces

• Energy efficiency considerations

The Arduino platform is widely used in education and rapid prototyping due to its:

• Open-source hardware architecture

• Simplified development environment

• Large ecosystem of libraries

• Affordable hardware modules

⚙️ Microcontroller Architecture Basics

An Arduino board typically contains:

• CPU (ATmega or ARM-based processor)

• SRAM (volatile memory)

• Flash memory (program storage)

• EEPROM (non-volatile data)

• GPIO pins

• ADC (Analog-to-Digital Converter)

• PWM outputs

• Communication interfaces (I2C, SPI, UART)

The core engineering concept behind Gemini Station’s escape system is real-time embedded control.

🌡 Sensor and Actuator Theory

In our space escape simulation, sensors detect environmental conditions:

• Temperature sensors (thermal overload detection)

• Gas sensors (air quality)

• Light sensors (power failure detection)

• Ultrasonic sensors (distance & docking verification)

Actuators respond:

• Buzzers (alarm)

• Servos (door locks)

• Relays (power cutoff)

• LCD displays (status interface)

• LEDs (visual alerts)

The engineering principle:
Input → Processing → Output → Feedback Loop
