so you have an atmega16 and ir sensors?
well, you can just write some simple code to say if one side gets more light turn that way so it stays on the line?
i couldn't really understand you well...

sorry but i hav tried dat, the pblm is how to write the logic . suppose my sensor senses black color then the receiver dsnt receiives light hence it is at a low potential, .
i am using port A  as my input port then
IF(PORTA==0X00)
THEN TURN LEFT();
but the pblm is it is not working , now wat logic shall i write for the voltage received dat  by the  receiver,???
