got some qrd114 sensors, and been looking on the internet for a setup of it, but still am struggling on how it is setup still =/. i need to also know what values are given to components and how it is figured out but dont know how to do it.

need a simple circuit diagram for phototransisotrs for a line following robot, following white line on black surface. i found this, http://docs.google.com/viewer?a=v&q=cache:cqvVSvJsjBoJ:www.optekinc.com/pdf/App%2520Bulletin%2520213-Opto%2520Assemblies.pdf+phototransistor+circuit&hl=en&gl=uk&pid=bl&srcid=ADGEEShv3VSBmZlWzrf1yMBeR4ND0I-dVFjLv8aanI_zsBzvJrDJq5KQ2roUgHJOPBGelhgjqKQ8ycF2WoFwTvnvEnwptPkX97_Yp6wW-59iT0lW7BkAn6P3LXsgQjhF8J7G1Oe4K8BO&sig=AHIEtbRkd3rLExp9NoKeXcmYu6jISSh-lQ
