A color will be archived while walking every morning on the specific route determined in the park. | | An Arduino with a color sensor records the data and this data (variety of pigments) will be use for to paint morning walks at Ilm Park.

| HELP: FINDING THE CORRECT USB PORT
| |
| if you can not find your arduino USB port, make a new file and add this code:
| |
| * CODE START *
| |
| import processing.serial.*;
| |
| // List all the available serial ports
| |
| printArray(Serial.list());
| |
| * CODE END *
| |
| It will print out a list of all your USB connections.
| |
| Find the [ ] number for your Arduino Port and include it in line 8 of this code.
