ContentsObjectiveThis tutorial will show you how to control the stepping motor by Microduino-Stepper module, and welding the stepping motor control board. Equipment
Stepper motor
Connect the stepper motor to Microduino-Stepper module:
Stepper motor parameters: 1.8deg/step, that is stepper motor moves one step turned every 1.8°.
Multiplied by 16 because Microduino A4982 default use 1/16 step mode. SchematicDebugging
Programming
ResultWe can control the four-wire two-phase stepping motor successfully by Microduino-Stepper module. Video |
