Arduino Halloween Party

Step 1: What You Will Need

Arduino UNO (or any other Arduino)

• Neopixel LED ring
• Halloween pumpkin (can be decorative)
• Jumper wires
• Visuino program: Download Visuino

Step 2: The Circuit

• Connect LED Ring pin [VCC] to Arduino pin [+5V]
• Connect LED Ring pin [GND] to Arduino pin [GND]
• Connect LED Ring pin [IN] or (DI) to Arduino digital pin [6]

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 "Random Clock Generator" component
• Add "Clock Multi Source" component
• Add "Random Color" component
• Add "NeoPixels" component

Step 5: In Visuino Set Components

• Select "RandomClockGenerator1" and in the properties window set "Max Frequency" to 20 and "Min Frequency" to 10
• Select "RandomColor1" and in the properties window set "Max" to clRed and "Min" to clBlack
• Double click on the "NeoPixels1" and in the "PixelGroups" window drag "Running Color" to the left
• On the left side of the "PixelGroups" window then select "Running Color" and in the properties window set "Count Pixels" to 12 or 16 (Depends on how many LED your LED ring is having)
• Close the "PixelGroups" window

Step 6: In Visuino Connect Components

• Connect "RandomClockGenerator1" pin [Out] to "ClockMultiSource1" component pin [In]
• Connect "ClockMultiSource1" pin [0] to "RandomColor1" component pin [Clock]
• Connect "ClockMultiSource1" pin [1] to "NeoPixels1" >"RunningColor1" component pin [Step]
• Connect "RandomColor1" component pin [Out] to "NeoPixels1" >"RunningColor1" component pin [Color]
• Connect "NeoPixels1" component pin [Out] to Arduino digital pin[6]

Step 7: 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 8: Play

If you place the LED Ring into the Halloween pumpkin and power the Arduino UNO module, the LED ring will start to change its colors that will imitate the fire in the Halloween pumpkin.
