Objective
This lesson will use potentiometer or serial port to control stepper moter's step, that is angle.
Equipment
Schematic
Debug
- Set up circuit, as follows:
Experiment one
- Step 1：Open the test program；
- Step 2：Compile it and select the board to downlaod
- Step 3：Test
- Connect the power (6-25V)；
- Rotate the potentiometer, stepper motor will rotate as the same angle.
Experiment two
- Step 1：Open the test program；
- Step 2：Compile it and select the board to downlaod
- Step 3：Test
- Connect the power (6-25V)；
- Open the serial monitor;
- Input a angle value, then the stepper motor will rotate as input angle value.
Result
Based on Microduino A4982, we can use the potentiometer or serial port to control stepper motor successfully.
