see trhe picture i have put on here
i need the pulse to drive (drive speed) the controller need a input pulse and a enable
its a steppenmotor controller
i also bay a arduino R4 minima but the can use the current program
i am not so good in this program wolrd its all new for me
so i need a pulse for the controller this pulse must be always there
whit the enable i set the motor on/off so to stop or drive or turn (one motor of the ohter dive)
