A stepper motor is a type of DC motor that works in discrete steps and used everywhere from a surveillance camera to sophisticated robots and machines. Stepper motors provide accurate controlling, and can be differentiated on the basis of torque, steps per revolution, and input voltage. In our previous project, we controlled 28-BYJ48 stepper motor using Arduino. 28-BYJ48 has relatively lower torque than the other stepper motors like NEMA 14, NEMA17.
In this tutorial, we are going to control NEMA17 stepper motor using Arduino Uno and A4988 stepper driver module. Nema17 stepper motor has higher torque and higher operating voltage than 28-BYJ48. Here a potentiometer will also be attached to control the direction of stepper motor.
