Line follower

Let's Make Robots Robots
1

Nothing much to describe about this robot.Its a simple line follower robot which uses 2 ldrs

and 2 leds as a sensor to follow line.

The robot is powered using two battery packs i.e. 9V battery for arduino and all other components and 6V battery for motors.

This is  the sensor which detects line.I will soon replace it with infrared transmitter and reciever for accurate line following.

Thank you.

Yes it is working fine.Will shoot a video and will upload it soon.

nice job Kawal! that

nice job Kawal! that breadboard’s H-bridge seems to be quite complicated!

It rather looks like a

L293D chip.
