hi guys, this is the first time ever i put my hands on stepper motor.
i am using unipolar stepper motor (1.8 degrees step angle)...
is it possible to control the desired angle of rotation using pic microcontroller.
for example i want my motor to rotate 7.2 degrees after every 1 second..
please somebody guide me about the step sequences to control the rotation.
Thanks
 

write code in this way
portb=0x03;
delay_ms(5);
portb=0x06;
delay_ms(5);
portb=0x0c;
delay_ms(5);
portb=0x09;
delay_ms(5);
portb=0;
delay_ms(980);

and for high torque apllication
write code in this way
portb=0x03;
delay_ms(250);
portb=0x06;
delay_ms(250);
portb=0x0c;
delay_ms(250);
portb=0x09;
delay_ms(250);

how to understand the logic behind this step sequence..... i mean why, 03,06,0c,09 ??
 

it has 2 coils with common joint which may be gnd or vcc or get help from google. if not understanding tell
