Status Update

• All parts have been acquired and tested
• System can differentiate between 6 colors red,
  yellow, green, blue, white, black
• Each color plays a note from a musical scale on
  the speaker
• Android phone flashed with 2.1 for bluetooth
  compatibility
• Gun form factor has been modified to fit
  electronics

Test Plan

• Color Detection
• Verify that the Arduino and color sensor can
  communicate and give different values for 6
  colors
• Use a color chart printed on paper in good
  lighting
• Battery Power
• Plug all components into the battery at once
  verify that they are all powered
• Bluetooth
• Send serial commands from Android to Arduino
• Speed
• Change colors are rapidly as possible and count
  number of changes per 10 seconds

Test Results

• Color Detection
• 6 colors are differentiated reliably red, blue,
  green, yellow, white, black
• Battery Power
• After more than 30 minutes of constant use,
  everything works fine.
• Bluetooth
• Still untested in development
• Speed
• Currently, the top speed is approximately 2
  colors per second

Test Results Speed

• Measure time for 10 detections of color (output
  over serial)

Risks Mitigation Updated
Risk Mitigation
Poor bluetooth connection Use most recent configuration settings Reconnect Wifi
Not enough light for camera to identify colors Add a brighter LED to light scene Calibrate system for darker colors
Battery life is shorter than expected Put in a new battery

Final Demo

• Cool, Compact, Wireless Gun Form Factor
• Powered by 9v Battery
• Android Phone Application
• Communicate over bluetooth to adjust the scale
  played on the gun
• Fun Colors to Listen To
• Markers, Crayons, paper, painted vinyl, and more!
• Mind-blowing
