About the project
In this tutorial we are going to control a stepper motor Nema 17 by using a 3rd Party EDP stepper component in Visuino.

Story
The EDP stepper component was created by Jim Ryan, you can read more about this component on his Patreon pagewhere you can also support his work.
Step 1: What You Will Need
- Arduino UNO (Or any other Arduino)
- Stepper motor NEMA 17
- A4988 Stepper Motor Driver or (DRV8825)
- DRV8825/A4988 Stepper Driver Expansion Module
- Jumper wires
- Power Supply 12V
- Visuino software: Download here
- Install Stepper Ramp EDP component Download here
- Arduino Digital Pin 2 will be used for Steps
- Arduino Digital Pin 3 will be used for Motor Direction
- Optional - Arduino Digital Pin 4 will can used for driver pin Enable
If using a Stepper Motor Driver Shield:
- Connect Motor Shield GND pin to Arduino negative pin [GND]
- Connect Motor Shield [5V] pin to Arduino positive pin [5V]
- Connect Motor Shield GND pin to Power Supply negative pin [GND]
- Connect Motor Shield [9V] pin to Power Supply positive pin [+]
- Connect Motor Shield pin[S] to Arduino digital pin [2]
- Connect Motor Shield pin[D] to Arduino digital pin [3]
- Connect stepper motor as shown on the picture.
If using a Stepper Motor Driver 8825:
- Connect DRV8825 GND pin to Arduino negative pin [GND]
- Connect DRV8825 DIR pin to Arduino digital pin [3]
- Connect DRV8825 STEP pin to Arduino digital pin [2]
- Connect Power Supply for the motor to DRV8825 VMOT and GND
- Connect Capacitor across VMOT and GND
- Connect stepper motor as shown on the picture.
Note: If you plan to use Pin for Enable, then connect it to Arduino digital pin [4] or any other free digital pin
Step 3: Start Visuino, and Select the Arduino UNO Board Type
Start Visuino as shown in the first picture Click on the "Tools" button on the Arduino component (Picture 1) in Visuino When the dialog appears, select "Arduino UNO" as shown on Picture 2
Step 4: In Visuino Add Components
- Add "Stepper Ramp EDP" component
- Add 3X "Integer Value" component
- Select "IntegerValue1" and in the properties window under "Value" set the Speed of the motor in our case we will use 1000
- Select "IntegerValue2" and in the properties window under "Value" set the Acceleration Speed & Deceleration Speed of the motor so called Ramp Up and Ramp Down where you set how many steps it should Accelerate and Deaccelerate, in our case we will use 1000
Note that if you do not want to use the Ramp Up or Ramp down of the stepper motor then just don't use this step
- Select "IntegerValue3" and in the properties window under "Value" set the amount of steps, in our case we will use 8000
- Connect "IntegerValue1" pin [Out] to "StepperRampEDP1" pin [Frequency]
- If you plan to use Ramp Up & Ramp Down then Connect "IntegerValue2" pin [Out] to "StepperRampEDP1" pin [Ramp Steps]
- Connect "IntegerValue3" pin [Out] to "StepperRampEDP1" pin [Total Steps]
- Connect "Start1" to "StepperRampEDP1" pin [Start]
- Connect "StepperRampEDP1" pin [Ena] to Arduino digital pin [4]
- Connect "StepperRampEDP1" pin [Dir] to Arduino digital pin [3]
- Connect "StepperRampEDP1" pin [Pul] to Arduino digital pin [2]
In Visuino, at the bottom click on the "Build" Tab, make sure the correct port is selected, then click on the "Compile/Build and Upload" button.
Step 8: To Use Return Type (Dir)
To return the motor position to the start after it finishes the steps, we can select "StepperRampEDP1" and set "Return Type (Dir)" to true, this means that when it finishes the steps if you start it again by sending the clock pulse to the "Start" pin it will reverse and do the same amount of steps backward.
To test this we are going to add the "Sequence" component, in the properties window set "Repeat" to True, double click on the "Sequence1" and in the "Elements" window drag 2X "Period" to the left side, for the first period in the properties window set "Interval" to 1000, this meant that it will be activated after 1s, for the second period set in the properties window "Interval" to 10000, this meant that it will be activated after 10s.
- Close the "Elements" window
- Connect pins [Out] of both Periods to the "StepperRampEDP1" pin [start]
- Connect "Start1" pin [Out] to "Sequence1" pin [start]
