SQUID Game Timer with Doll and Sound- SQUIDUINO Red Light Green Light Interactive Toy + AU Stock

This project is called SQUIDUINO and it resembles ‘Squid Game’s Red Light Green Light’ game. This project is sold as fully assembled toy. We have named it SQUIDUINO, a combination of Squid Game and Arduino :).

This is a hand made toy. The enclosure is 3D printed. If you have watched the popular Series Squid Game where they play RED LIGHT GREEN LIGHT game, you will understand how it works. 

Bring the iconic suspense of the hit series home with the Interactive Red Light, Green Light Toy Kit! Designed for endless fun, interactive group play, or as a creative DIY project for kids, this mini gaming device brings the famous game straight to your tabletop.

The major parts of SQUIDUINO are:

• PIR Motion sensor
• MP3 player with 2GB microSD card. The 2GB microSD card comes with 8 sounds to give you a feel of Squid Game. Download the sounds here: With Gunshot and With Guitar
• 0.56″ TM1637 display module working as a countdown timer

Other supporting components are:

• Buzzer
• 3 x RGB LEDs
• Speaker
• Buttons

Key Features & How It Works

Unpredictable Game Phases: The motorized doll turns away during Green Light (with sound effects) and turns around to scan players during Red Light (accompanied by iconic audio cues). The state changes automatically at random intervals, ensuring no two games are ever the same!

Adjustable Game Timer: Built-in digital display supports customizable gameplay durations set between 01:00 and 05:00 minutes.

Optional Motion Detection Feature: Features an integrated PIR motion sensor. When active, detecting movement during the Red Light phase sounds the buzzer and illuminates a Blue Motion LED.

Optional Mute Function: Because PIR sensors operate differently than camera vision systems, wide room play can cause occasional false triggers. The red button at the bottom right allows you to toggle the motion sensor ON or OFF, letting kids play by traditional referee rules without unexpected sensor alarms.

Hardware & Controls

For Arduino Enthusiasts: Powered by an Arduino UNO architecture, all high-quality voice prompts and atmospheric game audio are driven by an onboard dedicated MP3 player module for crisp sound delivery.

Black Button: System Reset

Yellow Button: Play Game Rules Audio

White Button: Set Countdown Time (01:00 to 05:00)

Green Button: Start Game

Red Button (Top): Stop / Return to Idle

Red Button (Bottom Right): Toggle Motion Sensor Active / Deactivated

DIY Paintable Doll & Creative Play

The included 3D-printed doll figurine comes in a clean, unpainted white finish. This makes it an engaging creative craft activity for children—kids can paint, color, and customize the doll's hair, dress, and details before starting the game!

What’s not in this project?

This project does not have a camera. It has a basic PIR motion sensor that can sense motion like any other motion detectors. It cannot specifically point out the players like in Squid Game Series. Motion detector also has a range. It can detect up to 3 meters only. The device is made just for fun that you can play at home during a party. Kids can also play this game (you can remove the gunshot sound). The good thing is that the doll turns around when it plays GREEN LIGHT/RED LIGHT that can excite children.

Important Build & Finish Note

This item is a custom 3D-printed hobby toy kit housed in a translucent PETG enclosure.

Please note that as a 3D-printed, hand-assembled craft product, the surface will naturally exhibit standard additive-manufacturing characteristics—including visible print layer lines, minor surface marks, and small assembly glue traces. These functional cosmetic traits do not affect durability or performance and reflect the authentic handmade nature of custom electronic prototyping kits!

Package includes:

1 x Squiduino 

1 x Squid Game Doll

1 x Servo Motor

You will need a 5V 2A power supply to operate Squiduino. A normal phone charger would work.

Frequently asked questions (FAQs)

1. Can we remove or change the gunshot sound?

Yes, you can easily do that by removing the gunshot sound from the MicroSD card. For your convenience, there are two sets of sound: With Gunshot and  With Guitar. With the gunshot set, you will hear a gunshot and with the guitar set, you will hear a guitar sound in place of the gunshot.

2. Is the speaker loud enough?

Yes, the speaker’s sound is loud enough to be heard in a room.

3. Can it detect specific players as in the Squid Game series?

No, it cannot detect specific players. It has a basic motion sensor. It can detect motion but it cannot tell which player moved. Motion detector also has a range. It can detect up to 3 meters only.
