Hello I want to make a sensor device to detect colors from a thin beam of light, I was wondering If I should use 3/4 filtered photo diodes or a photodiode rgb sensor. Also I was wondering the easiest way of getting these components , I live in Northampton in UK.
Sorry If there is any inconsistency In my post I apologize in advance , I am novice on this subject at best.
Thanx
