Software for Color Sensors

1. Basic demonstration

• TCS230 sensor: BASIC Stamp II code
• ColorPAL sensor Arduino code

2. Color Matching Demo software

Following Arduino code works with an original Parallax (or PhiPi) ColorDemo.exe program available at the following address: http://www.parallax.com/Portals/0/Downloads/docs/prod/sens/ColorPAL_programs.zip

• TCS230 sensor: BASIC Stamp II code
• ColorPAL sensor Arduino code

3. Processing software

• PC software: Processing code
• TCS230 sensor: BASIC Stamp II code
• ColorPAL sensor Arduino code

// Demonstration program for Color Sensors
// TCS 230 sensor requires TCS230_Demo03_SS_CIM.bs2
// ColorPAL sensor requires ColorPAL_Demo03_SS_CIM.ino with line 78 uncommented
