Bipolar stepper motors
Unipolar stepper motors are easy to control at the cost of low efficiency and power. Bipolar stepper motors have much higher efficiency and torque; however they are much harder to control. To fully control one, two H-bridges are required. Luckily there are multiple Arduino-compatible bipolar stepper drivers out there. Here we will explore a few options.
Getting ready
We can control a bipolar stepper motor using the Arduino Motor Shield. Here are the ingredients needed for this recipe:
- An Arduino board connected to a computer via USB
- An Arduino Motor Shield
- A bipolar stepper motor
How to do it…
We connect the stepper motor to the shield using the following steps:
- Carefully mount the Arduino Motor Shield on top of the Arduino. Be ...
