Hi, I found maybe a error into project on the project book.
Page 57, it set up const int green/red/blueLEDPin number, from figure 01 construction. the right pin number for red/blue will redLEDPin = 10, and blueLEDPin = 11.
I find this result because I use flashlight illuminate on blue but the LED become more "Red"!
Thanks,,
