requirements.md

Project Requirements Overview

Core Components Needed

Microcontroller/Development Board

• ESP32 would be an ideal choice because:
  • Built-in WiFi capabilities
  • Multiple GPIO pins for expansion
  • Large community support
  • Arduino-compatible for easier programming
  • Breadboard-friendly development boards available
  • Reasonably priced

Camera Module

• ESP32-CAM or OV2640 camera module recommended:
  • Compatible with ESP32
  • Plug-and-play capability
  • Good documentation available
  • Breadboard-friendly
  • Relatively inexpensive

Additional Hardware

1. Breadboard

   • Standard size breadboard for prototyping
   • Multiple power rails recommended

2. Jumper Wires

   • Male-to-male
   • Male-to-female
   • Female-to-female (a few for flexibility)

3. Power Supply

   • USB cable for programming and power
   • Optional: External 5V power supply

4. Basic Electronic Components

   • LED indicators
   • Resistors (various values, including pull-up resistors)
   • Capacitors for power stability

Development Tools

Software Requirements

1. Arduino IDE or PlatformIO
2. ESP32 board support package
3. Required camera libraries
4. WiFi libraries (usually included with ESP32 package)

Optional Tools

• USB-TTL adapter (if not included on the development board)
• Digital multimeter for testing
• Logic analyzer (helpful for debugging)

Getting Started Steps

1. Initial Setup

   • Purchase components
   • Install development environment
   • Install required board packages and libraries

2. Breadboard Assembly

   • Connect ESP32 to breadboard
   • Wire up basic power connections
   • Add status LEDs for debugging

3. Camera Integration

   • Connect camera module using appropriate pins
   • Test basic functionality
   • Implement image capture code

4. WiFi Implementation

   • Test WiFi connectivity
   • Implement basic data transfer
   • Set up image transfer capabilities

Notes

• No soldering required for initial prototyping
• All components should be breadboard-compatible
• Modular approach allows for easy modifications
• Can be expanded with additional sensors later

Next Steps

1. Verify component availability
2. Create detailed wiring diagram
3. Set up development environment
4. Begin incremental testing
