hi,all can any one give me site for book or tutorial of how to calculate number of pulses and duration of delay to rotate stepper motor in particular angles
 

my friend it is important to read about microstepping if you need to master stepper motors

anyway if you just want to rotate a stepper motor normally around 200step per rovoultion , read the rated RPM and make delay that makes this possible ,

usually most stepper are in the 100-200rpm range , SO lets take at 120 rpm as a guess : then it rotates 2 times per second , each rotation is 200 step , then 100 step per second , and divide 1/100 = 10ms . Use 10ms delay and i think it will work , then start deceasing until the motor starts slipping and losing steps . this is the easiest way . unless you want to measure inductance by RLC meter and have full datasheet from manufacutre

hope that helps , good luck
