2. Objective
The objective of this project is to build a low cost motion detection device that will detect a human presence.

3. Low cost components Advanced Capabilities for Interfacing
Initial Thoughts
Low cost components
Advanced Capabilities for Interfacing
→ Components combined price under $20
→ Can program in Arduino IDE and AVRdude (command line terminal)

4. Basic Outline of Steps Involved
Order parts
Design circuit(s) on paper/software
Test all parts for compatibility
Build device
5. Develop code
6. Test and modify
7. Design and 3D print housing
8. Encase in housing and present

5. Equipment Adafruit Trinket Mini Pinhole camera
Additional basic electronic components
3D printer
Equipment
Pinhole camera
Adafruit Trinket Mini

6. Obstacles
There will be several unexpected troubleshooting and bug fixes, which we have dedicated time reserved.
The optical receivers being used to detect the actual motion will need a lot of tuning as to not be too sensitive.

7. Progression Researched Trinket Downloaded drivers and libraries
Troubleshooted code issues

8. Progression Interfaced with spy cam
Began coding motion detection sequence
Researching topics:
image analysis and processing
File structure and manipulation for Trinket

9. Image Analysis
Researching file organization and manipulation of image format used by optical sensor
File Manipulation for program control
Pixel Comparison
Ability to program the Trinket directly with AVR-GCC as the compiler ( command line interface)

10. Potential Issues
Information may have to be sent and processed at another computer
Complex algorithms may be needed for human detection
Processing speed may need to be boosted
