Halloween Project: Squid Game's Doll

Since its premiere a few weeks ago, The Squid Game has become the series everyone is talking about with over 111 million viewers, breaking an all-time record on its launch.

The combination of children's games with a sadistic and terrifying trigger has captivated people and made the series a success.

In our Halloween-themed project, which is an ancient tradition, we have taken inspiration from the current hit series for its sadistic component, merging tradition with the present day.

Specifically, we have been inspired by one of the games of the series: 'red light and green light', traditionally known as 'pica paret', although in the series the game is controlled by a doll.

In our project, we have recreated the doll by equipping it with an ultrasound sensor to detect movement, LEDs and a buzzer to inform about the phase of the game.

In this Instructable, we will show you the process we have followed to recreate the game and be able to play this Halloween.

First, we analyzed the game series and established the functions we wanted to realize in our project in order to create our flowchart.

Then, we listed the necessary components, and next we looked for a 3D model of the doll, which we printed out and made the necessary changes to allow for the wiring.

Before printing it’s necessary to make some adjustments so the assembly process is easier. Divide the 3D model in half vertically (as in the picture) and create a gap behind the eyes of the doll to place the leds. In the doll’s body create guides so the wires can hide. 

3D print the doll. 

Separately print (or find) a hollow base to hide the controller board and to put the doll on top. 

Once you have your doll and base the assembly is very simple.  

Place the leds in the eyes and hide the wires in the guides made earlier. Stick the doll to the base and put the controller board in the hollow space. 

Now you’re ready to play.



Conclusion

Building this project was easy but making the code work was a rollercoaster. Finally we made our programming work after multiple setbacks and we are proud of the outcome. 

In conclusion, this project has been a good way to put into practice our knowledge of Arduino and its various components and we are looking forward to use it in future projects.
