Color sensing with a pro mini


I'm Bjorn and I'm trying to sensing colour from skittles. It's a project that I make for school but I have some problems.
I like to use the arduino pro mini but it wouldn't work very well. When I try to read the color in the serial monitor I get a lot of different characters and not the expected data numbers.

What I get from the serial monitor is:
ffff and a lot of other characters
while i expect something as R= 50 B=45 G=12 and a lot of other data like that but with different numbers

I already tried to change the baud rate but it dindn't help.

Who knows what to do? :confused:


Do you have a color sensor?
If so, did you connect it to the Pro Mini?
