Single white line detector for SUMO ROBOT

Every ROBOT entering a SUMO contest needs a white line detector not to fall out of the DOJO (Arena with a white border ! Build this circuit and get ready for combat ! This circuit uses 1/2 of a LM358 OpAmp so if you decide to do a line follower instead of a single line detector you’ll just need to add components to it’s right side !”
