hey guys, i am planning to make a line follower robot.. since i am a beginner, i decided to make one without using microcontroller. instead, i am using a motor driver ic and a voltage comparator ic. i have been told that i need to use a 7404 not gate ic(inverter ic) too, to make the wheels rotate in opposite direction... but, i dont know how to connect it(ic 7404) in the circuit. would you please let me know how to connect ic7404??
