Hi, I am using a 1.8 degree stepper motor for my robot. i'm using ATmega16 microcontroller for interfacing and i'm writing the code in AVRstudio 4. my problem is i'mgetting output when i use while loop for rotating the motor and the motor also rotates continuously.but if i want to control the angle means i've to give use for loop for accurate stepping..but i cant get rotation for when i use FOR loop....pls help me..
