This is the circuit which is used to construct a line following robot without using micro controller and programmable circuit. So, to make the experiment simple, 555 timer is used
           In this circuit in place of two Potentiometer we replace with a LDR [Due to unavailable of LDR in this software Potentiometer are used] to sense the intensity of light reflection from the line drawn. 
In this way the two motors can be controlled.
