i want to control speed of DC motor using arduino via matlab. I am not using any extra circuitry to control speed of motor. i tried to do it with analogWrite but it didn't work it just controlled the duty cycle of the motor. i need some command through which I can directly control the speed of motor. i am using arduino uno as an interface between motor and matlab. can any one suggest something that may help?
