By setting appropriate logic levels to these pins, we can set the motors to one of the six-step resolutions. You can change the step resolution using the microstep pins (M0, M1 & M2). full-step, half-step, quarter-step, eighth-step, sixteenth-step, and thirty-second-step. This driver can operate stepper motor in six different step modes i.e. Nema 17 motor driver DRV8825 has a maximum output capacity of 45V and ± 2.2 A. STEP pin is used to control the steps, and DIR pin is used to control the direction of rotation. This Nema 17 stepper driver module has a built-in translator that means that it can control both speed and direction of a bipolar stepper motor like NEMA 17 using only two pins, i.e.
It is used to control bipolar stepper motors. The DRV8825 is a microstepping driver module similar to the A4988 module. Stepper drivers send the current to stepper motor through various phases. We previously controlled the same Nema17 stepper motor with A4988 stepper driver and Arduino.Ī stepper driver module controls the working of a stepper motor. We will also use a potentiometer to control the direction of the stepper motor to rotate it in clockwise and anti-clockwise direction. In this tutorial, we are going to control NEMA 17 stepper motor using Arduino and DRV8825 stepper module. 28-BYJ48 has relatively lower torque than the other stepper motors like NEMA 14, NEMA17. In our previous project, we controlled 28-BYJ48 stepper motor using Arduino. Stepper motor can be operated in different step modes such as full step, half step, ¼ step by applying appropriate logic levels to microstep pins of stepper module. By changing the rate of the control signal applied, we can easily control the motor speed. NEMA 17 stepper motor has a step angle of 1.8° that means it will take 200 steps for a 360° rotation. 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.
