Talking Skull

One of the most popular Arduino Halloween projects is the talking skull. It’s a project that can be done by almost anyone and requires minimal tools. In this section, we’ll discuss how to build your own talking skeleton step-by-step.

You will need:

  • Jumper wires
  • A small breadboard
  • Mp3 player module
  • 2 LED lights
  • 1 Arduino Uno
  • 1 Motion sensor module
  • Plastic Halloween skull
  • 1 micro SD card (max. 16 Gbs) and a SD adapter

How this project works is simple. The motion sensor will detect when someone is nearby and will trigger the Arduino Uno to activate the Mp3 player module. This in turn will play a sound file from the micro SD card, which can be customized by you. At the same time, this action will also light up the two LED lights.

Talking Skull

First thing first, you need to connect all the hardware components to the Arduino Uno. Connect all the LEDs together in a daisy chain, and then connect them to the Arduino. To get started, attach the power and ground rails from your breadboard to the Arduino Uno’s 5V and GND pins respectively. Next step is connecting the motion sensor module, neopixel and mp3 module to your Arduino.

Once all hardware components are connected, you will need to upload any sound files you want for your talking skull onto a micro SD card with an SD adapter. The Mp3 module should be able to detect the sound files from your card once it is inserted into the module.

Finally, you need to upload a sketch onto your Arduino Uno so that it can interpret any input signals from your motion sensor and trigger all other components accordingly. You can find several tutorials online with code snippets ready for use.

Find a mock skull and place all components inside it. You can make a hollow space for the motion sensor and LEDs, or attach them to the surface of your skull with adhesive tape or zip ties.

Once everything is ready, turn on the power switch and you’ll have your own custom talking skull! Now whenever someone walks by, they’ll be in for a surprise as your spooky skeleton talks away! Have fun watching people jump when they hear its eerie sounds.

Smoking Pumpkin

Building a smoking pumpkin is an easy and amazing project you can do with your Arduino. With this, you can easily create a spooky atmosphere and make an impressive decoration for your Halloween party.

You will need the following components to build a smoking pumpkin: Arduino board, mist maker using 555, relay module, IR module, neopixel led, 3D printed pumpkin enclosure, battery.

First of all, we need to build a circuit for a mist maker, this too will require components:

  • Piezoelectric disc
  • NE555
  • 220uH inductor
  • 10nf capacitor
  • 2*100nf capacitors
  • 10 ohm resistor
  • 5k variable resistor

Connect these components according to one of the many tutorials available online. Then connect them to the Arduino board.

Next, you will need to connect the rest of the components, wires should be attached to their modules and then connect the ground and VCC of the IR module to Neopixel VCC and ground. The common positive should go to 5v and common ground to the ground of Arduino. IR output is connected to pin 3 of Arduino and neopixel data into pin 6. Lastly, the ground and VCC of the relay module should go together to Arduino and relay input to pin 2. Now, attach a battery to your mist maker via relay module.

Talking Skull

Now you are ready to write the code. Begin by including libraries required to run neopixel and IR modules. Set the pinModes to the relevant pins and then create a function for the LED, this should define the color of the LEDs and length of time it will last. Again, you can find a variety of source codes online.

Next, create a 3D model of a pumpkin using an application such as Rhino 3D. This model should include an enclosure for the mist maker and place holders for neopixel LEDs.

Print out the model using a 3D printer, then assemble all components into the enclosure. Make sure to secure everything with glue or screws if necessary. Now your smoking pumpkin is ready!

Place the piezo on the water and cover it with a pumpkin enclosure. Connect the 12v battery and turn on the Arduino board. The smoking pumpkin is now ready and will start functioning based on your code. You can adjust the code according to what you want it to do during Halloween night and enjoy your spooky setup!
