In this instructables I will show you how to make a line tracer robot without using any kind of microcontroller.
It is basically works on the property of reflection of light is greater from whiter surface than black surface. Hence when the robot sensors on the black path it receives less light than desired quantity of light and hence the motor stops rotating.

To make this robot you will need the following components:
1.LM358 op-amp chip
2. 220 ohm resistors x 4
3. 1k resistor x 2
4. BC547B transistor (NPN) x 2
5. white LED x 2
6. red LED x 2
7. 3 or 6V DC geared motors x 2
8. copper clad circuit board or protoboard
9. 100k pot x 2
10.5k pot x 2
11. photo-diode x 2
& now you are ready to make ur project…

refer the given images carefully..!!
trans. acts as on-off switch to the motor. when photo diode on black path it switch offs opamp i.e. 1 motor and 2nd motor is runs due to sensor on white floor..
on turns due to rotation of only 1 motor robot can also turns..
Thank you!
its a black tape and gray dots are actully name of company of black tape..!! :) :)
