keep it up.


simple but use full



it is quit simple


it cannt be excuted


why can't it?

Check with connections...

We have tested it before uploading...

effective ^^



give full code plzzzzzzz


which controller u hv used in this project?



You are welcome :)

Its based on 8051 controller...!!
Program was tested on P89V51RD2BN.

Thanks for sharing this simple line follower robot project. It is very useful for me

You are welcome Madhavi :)

wow its working and making fast line follower


You are welcome :)

Its fast because its using less complex yet effective way of testing the sensors and providing output.

Hello Am new at this. I've made several circuits but I've never done programming. There's a CODE2 link given, what is that for? And if that is for programming can you tell me the software and hardware I should buy? And how to program it

i want code for avrstudio atmeg8


If you have worked on the given code, you can easliy make the same for AVR also.


Actually programming in AVR is easier than 8051


You are welcome

ala code free ma al ne...!
