Story

Step 1: What You Will Need

1 / 2

Step 2: Start Visuino, and Select the Atom Matrix Board Type

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 "Atom Matrix" as shown on Picture 2

Step 3: In Visuino Add Components

1 / 5

  • Add "Clock Generator" component
  • Add "Counter" component
  • Add "Integer Multi Source" component
  • Clock "Demux(Multiple Output channel Switch)" component
  • Add "Color Value" component
  • Add "Color Multi Source" component

Step 4: In Visuino Set Components

1 / 10

  • Select "M5 Stack ATOM Matrix" board and in the properties window expand "Modules">"RGB Matrix">"Elements" and click on the 3 dots button
  • In the "Elements" window drag "Fill Screen" to the left side
  • Close the "Elements" window
  • Select "ClockGenerator1" and in the properties window set "Frequency" to 0.3
  • Select "Counter1" and in the properties window set "Max>Value" to 3 and "Min>Value" to 0
  • Select "ClockDemmux1" and in the properties window set "Output Pins" to 4
  • Double click on the "ColorValue1" and in the Elements window drag "Set Value" to the left side and in the properties window set "Value" to ClRed
  • in the Elements window drag another "Set Value" to the left side and in the properties window set "Value" to clYellow
  • in the Elements window drag another "Set Value" to the left side and in the properties window set "Value" to clGreen
  • in the Elements window drag another "Set Value" to the left side and in the properties window set "Value" to clYellow
  • Close the Elements window

Step 5: In Visuino Connect Components

1 / 2

  • Connect "ClockGenerator1" pin [Out] to "Counter1" pin [In]
  • Connect "Counter1" pin [Out] to "IntegerMultiSource1" pin [In]
  • Connect "IntegerMultiSource1" pin [0] to "ClockDemmux1" pin [Select]
  • Connect "IntegerMultiSource1" pin [1] to "ClockDemmux1" pin [In]
  • Connect "ClockDemmux1" pin [0] to "ColorValue1" > "Set Value1" pin [In]
  • Connect "ClockDemmux1" pin [1] to "ColorValue1" > "Set Value2" pin [In]
  • Connect "ClockDemmux1" pin [2] to "ColorValue1" > "Set Value3" pin [In]
  • Connect "ClockDemmux1" pin [3] to "ColorValue1" > "Set Value4" pin [In]
  • Connect "ColorValue1" pin [Out] to "ColorMultiSource1" pin [In]
  • Connect "ColorMultiSource1" pin [0] to "M5 Stack ATOM Matrix" > "Fill Screen1" pin [In]
  • Connect "ColorMultiSource1" pin [0] to "M5 Stack ATOM Matrix" > "Fill Screen1" pin [Clock]

Step 6: 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.

Step 7: Play

If you power the ATOM Matrix module The Display will start to show the Traffic Lights.
