digitalWrite(stepPin, HIGH);digitalWrite(stepPin, LOW);
My point is that I want a smooth motor that does not stop each increment.
Steppers can be made to move more smoothly by micro-stepping. Micro-stepping is basically two sine waves out of phase, which can be synthesized by varying the PWM duty cycle.http://softsolder.com/2011/05/05/thing-o-matic-mbi-stepper-motor-analysis/
Do you mean use 1-3 outputs with PWM to control smooth ?

The stepper driver board figures out how to make that happen. The Arduino just sends step pulses.When you use microstepping the torque of the motor is reduced because the microstepping is achieved by using the coils to pull against each other.1350 km/h is not slow - I think it is close to the speed of sound. Are you sure you have your units correct?I can't figure how one revolution can be 10 km. That implies a wheel that is over 3 km in diameter.Tell us what you are actually trying to do...R
I can't read your lips because I am deaf. It's truth.
10 km is a measure of each revolution. I am trying to building a km counter decreasing to the waypoint or ahead while increasing.
I am building one home cockpit; Ilyushin Il-62 (not M model but maybe M anyway).
Maybe it is better I am making one blog homepage that describes everything I am doing while I am doing this.
