Turn The :MOVE Motor Into A Radio Controlled Halloween SpookMobile

The Spookmobile. Wraith Wagon. Spectre Sedan. AaAaAaAAaaAAutomobile. All good names for this make, but I certainly couldn’t choose so I’ve included them all.

This is a simple make that sits on top of your :MOVE Motor and adds some Halloween drama to your remote-controlled buggy. The LEDs are used to replicate the flickering of candles, and the V2 micro:bit’s speaker is used to make a ghostly noise when you shake the remote micro:bit. Follow along with Emma's instructions and mod your :MOVE Motor.

We Used: 

For the Ghost:

  • White Material.
  • Thread and Needle (Or a Sewing Machine).
  • Googly eyes.
  • A Black Pen.
  • Thick Wire (You could use a wire hanger).
  • Tape.
  • A stuffing material such as scrap material, paper or stuffing.
  • Two discs of sturdy material.
  • 1 x 16mm M3 Pan Head Screw.
  • 1 x M3 Hex Nut.


This make falls into three sections:

  1. Make the Ghost
  2. Attach the Ghost
  3. Code the Spookmobile

In essence, the first two sections can be done however you want to do them. A 2D paper ghost on a spring taped to your buggy could still be spooky!

Making The Ghost:

Step 1 - Framed:

Build an armature for your ghost. This is like a metal skeleton which will hold the ghost in position. I have coiled a thick wire to give the skeleton some thickness to build off of so that the lower portion of the wire that is not covered by the ghost will act as a spring.


Step 2 - The Body:

Next, build a body shape off of the armature. I’ve used a stuffing material held down with tape to build the ghost. Make yours any shape you like!


Step 3 - Adding the Costume:

Lastly, cover with a costume! I made a tailored ghost-sheet-costume on a sewing machine, then added googly eyes and a marker pen mouth.



Attaching The Ghost:

Step 1 - The Screw: 

Make sure the bottom of your Armature is coiled in a tight enough loop to wrap snugly around the M3 screw. This is so that it can be secured down using the screw.

Step 2 - The Pen Hole: In order to attach the ghost, we are going to use the pen hole in the centre of the PCB. Using appropriate means, cut from a sturdy material two discs that are just slightly larger than the pen hole - ours are 13mm in diameter. In the centre of each disc, cut a 3mm hole to accommodate the screw.


Step 3 - Assembly:

As above, attach the ghost using the Screw and Hex nut, securing the wire armature to the two discs on either side of the pen hole.


Coding The Spookmobile:

The code for this buggy is in two parts: A Transmitter and a Receiver. This means you will use one micro:bit as a radio control for the other, which will be plugged into the :MOVE Motor. The transmitter code is as follows:

The transmi

This is a simple bit of micro:bit code that uses the radio controls to send words (“strings”) to the other microbit. Depending on the input, a different string will be sent which the other micro:bit will correspond to different movements. The receiver code is as follows:

This code allows the receiver micro:bit to translate the words sent by the transmitter micro:bit into movements. It will have the :MOVE Motor perform different actions depending on the word it receives.

This code also has two spooky additions: Flickering candle-style LEDs and a spooky ghost noise made using the “sad” audio preset in MakeCode.
