- Connect potentiometer pin [GND] to the breadboard pin [GND]
1 / 2
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 5: In Visuino Add Components1 / 4
- Add "4 Wire Stepper Motor" component
- Add "Debounce Button" component
- Add "Toggle(T) Flip-Flop" component
- Add "Map Range Analog" component
1 / 3
- Select "MapRange1" and in the properties window set "Output Range" > "Max" to 500 <<this will be the maximum steps per second
- Select "Stepper1" and in the properties window select "Reversed" & click on the pin icon and select "Boolean SinkPin" and select "Steps Per Second" & click on the pin icon and select "Float SinkPin"
- Connect Arduino Digital pin [2] to "Button1" pin [In]
- Connect Arduino Analog pin [0] to "MapRange1" pin [In]
- Connect "Button1" pin [Out] to "TFlipFlop1" pin [Clock]
- Connect "TFlipFlop1" pin [Out] to "Stepper1" pin [Reversed]
- Connect "MapRange1" pin [Out] to "Stepper1" pin [Steps Per Second]
- Connect "Stepper1" pin [0] to Arduino digital pin [8]
- Connect "Stepper1" pin [1] to Arduino digital pin [9]
- Connect "Stepper1" pin [2] to Arduino digital pin [10]
- Connect "Stepper1" pin [3] to Arduino digital pin [11]
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 9: PlayIf you power the Arduino module, The motor will do will start to run and with the potentiometer you can change the speed. If you press the button the motor will change the direction.
