Start Visuino, and Select the Arduino MEGA 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 Mega 2560" as shown in Picture 2
In Visuino, Add Components
Add "Keypad" component
Add "Char Multi Source" component
Add "Char To Text" component
Add 2X "Compare Char Value" component
Add "Toggle(T) Flip-Flop" component
Add "Delay" component
Add "Ignore Text Values" component
Add "Text To Integer" component
Add "Pulse Generator" component
Add "Up/Down Counter" component
Add "4 Wire Stepper Motor" component
In Visuino Set Components
Double click on "Keypad1" and in the "Keys" window, drag "Character Key Group" to the left side. In the properties window, select "Keys" and click on the 3-dot button. Now, in a "Keys" window, drag 16X "Char Key" to the Left side, and for each key set "Character" in the properties window, set "Character" for each in the order as you see in picture 6, for
"Char Key1" the "Character" will be 1
for "Char Key2" the "Character" will be 4
for "Char Key3" the "Character" will be 7
for "Char Key4" the "Character" will be *
for "Char Key5" the "Character" will be 2
and so on until the end
Close All the Windows
Select "CharMultiSource1" and in the properties window set "Output Pins" to 4
Select "Delay1" and in the properties window, set "Interval (uS)" to 5000000
Select "CharToText1" and in the properties window, set "Update On Each Char" to True
Select "IgnoreTextValues1" and in the properties window, set "Ignore Case" to True, "Pass Values Bellow" to True, and "Value" to A
Select "CompareValue1" and in the properties window set "Value" to A
Select "CompareValue2" and in the properties window set "Value" to D
Select "PulseGenerator1" and in the properties window, set "Frequency" to 1000 <<This will be the speed for the stepper motor, and you can adjust it if you want
Here we are going to handle the Steps: Select "UpDownCounter1" and in the properties window set "Initial Value" to 1000, "Min">"Roll Over" to False, "Min" > "Value" to 0
Select "UpDownCounter1" and in the properties window select "Initial Value" and click on the Pin Icon and select "Integer SinkPin"
Select "Stepper1" and in the properties window select "Reversed" and click on the Pin Icon and select "Boolean SinkPin"

Generate, Compile, and Upload the Arduino Code
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.
Play
If you power the Arduino module, enter the number of steps on the keypad, and press the button "A", the stepper motor will start to rotate. If you press the button "D" on the keypad, then the stepper motor will change the rotating direction.
