Why Use a Driver Between Microcontroller and Motor Control?

Many students are puzzled when controlling motors, as the microcontroller pins can output high and low levels. Why can’t we connect the motor directly to make it turn? Why is a driver necessary? What is its purpose? There are so many different driver models. Is it possible to operate without one? Today, let’s discuss this. … Read more

Working Principle and Driving Methods of Stepper Motors

What is a Stepper Motor? A stepper motor is a type of motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. For a stepper motor, each input pulse signal causes the rotor to rotate by a certain angle or take a step forward. The output angular displacement or linear displacement is … Read more
