can any one help me... i feel the following program in not complete...the program executes with two warnings...but i don get any out put from the mc....some one pls tell me whether the program is correct and if it is complete(htis program was not written by me i got it from the net)...
thanks in advance
this is the schematic for the line follower the input is through the sensors and the output is to the motor driver my problem is i don get any output from the mc......
