Cluster 1: Adventures in Embedded Computer
SystemsInstructors: Dr. Rajesh Gupta, Dr. Choon Kim, Shirley Miranda, Arash Arafee, Bridget Benson
The Problem
• Over 6 million accidents per year
• Nearly 50,000 deaths per year
• 60% of accidents by human error
• $230 billion spent annually
Purpose
• In need of a better safety traffic system
• Traffic lights controlled by timers rather than present cars
• Synchronization of lights can save time and lives
Background Information
• C Programming Language
• PSoC Devices
• CapSense / Touch-Based Input
• Hardware / Wiring
• Multi-chip Communication
Hypothesis• Use CapSense to represent car
• Light turns green when car approaches intersection
• Perpendicular lights change automatically
• Two sets of lights are synchronized

Video Demonstration
Results and Data
• Successful, working device
• Realistic light cycle delays
• Very responsive to all finger motions
Conclusions
• Successful culmination of our knowledge of C and hardware
• Can be improved with a more efficient code
• Can be expanded to use 2 CapSense modules
Applications/Future
• Incorporate into suburban streets to reduce intersection accidents
• Applicable to any areas with controlled traffic
• Less traffic, save people, save time
