Hey, I know how to make detect an obstacle with IR sensors using OP-Amp. But I am supposed to make a circuit that does not involve any complicated ICs even OP-Amp. So can some one let me know how to detect an obstacle using MOSETs with IR sensors of course. Also help me know how to make LM193 type comparator using MOSFETs or transistors??
