Black & White Line Follower Robot 

                   I design a line follower bot that can follow track consisting of both black (on white surface) and white (on black surface) lines.

Line Follower Robot :

            Line follower Robot-Line follower is an autonomous robot which follows either black line in white are or white line in black area.

Components :

1. Arduino Nano
2. QTR-8A
3. BO 1 Gear Motors 100 RPM
4. LM293D ( Motor Driver IC )
5. Bo 1 Motor Wheel
6. LM7805 ( 5V voltage Regator ic )  
7. Push Switch
8. 10k Resister
9. 8 pin Female to Female jumper wire
10. Female Pin Socket For Arduino
11.  Pair of nuts and bolts
12. General Purpose PCB
