Jumanji game is a game that got idea from movie Jumanji. There is a scene in Jumanji where I can avoid traps and knives in a breathtaking way, and I wanted to make this scene a game.

## Step 1: The Material

material is as follows.

1. Arduino x 3

2. Stepping motor x 3 (42byghn1641a-05-c) and motor driver x 3 (L298N) for blade rotation

3. Trap block x 24 x 3 layers

4. Frightened accessory

5. Warning light and sound buzzer

6. Floor sensor (switch)

1 and 2 used the rest of the house. The motor used the remaining parts of the 3D printer, and the warning lights were purchased from the Internet. The amount was not so much. I made the missing parts by 3D printing as follows.

## Step 2: Work Order

Work was done with my sister lectures.

I moved to the idea meeting. Drawing the picture, I squeezed out the idea to make the Jumani game thrilling.

## Step 3: Panels and Sensors Assembly

I googled and found what materials I needed to make my work with an idea.

I bought stuff, and on top of that I thought about the way people go. I marked the traps between the roads.

Now, using materials, I made the game board and installed the detection center under the trap mark. If you step on it wrong, the warning light moves with the beep sound.

The block was made up of three floors so the sensor would not be visible.

## Step 4: Wiring and Coding

I bought the warning light as follows. I attached a motor to the blade mark, and finally soldered the wires together.

Finally, I coded the Arduino to make the motor rotation like below.

```// coding: Sunwoo and Yeonsu
//
#include <Stepper.h>
// motor name = 42byghn1641a-05-c
const int stepsPerRevolution = 200;  // change this to fit the number of steps per revolution for your motor Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);  // initialize the stepper library on pins 8 through 11
void setup() {
myStepper.setSpeed(120);    // set the speed at 60 RPM
Serial.begin(9600);
}
void loop()
{
Serial.println("clockwise");
myStepper.step(360);
delay(5000);
Serial.println("counter clockwise");
myStepper.step(-360);   delay(5000);
}```

## Step 5: Making Gifts for Friends

At the exhibition, we needed a pendant to hand out as we passed the game. My sister and I designed it with CAD, I made it by laser cutting.

## Step 6: Making Gem for My Cat

The game success saw the jewelry scene attached to the Jumanji leopard and thought about the idea. I made jewels with a 3D printer, and I put magnets on people without seeing them. I used a cat doll at home instead of a leopard. I put a magnet on the cat body, sew it well.

Like a game, when you step on a trap, your life is reduced one by one.

I made the story of the game in a way that if the user pitched the jewels to the leopard, he would succeed.

## Step 7: Test

My sister tested it. I corrected it a little if I had a problem.

## Step 8: Seoul Maker Fair 2018

On the day of the exhibition maker fair, I came early in the morning. It's already 10 o'clock.

I put pre-made game descriptions all over the place, I put a line on it and tried it out.

Soon there were more people. Everyone enjoyed the game, and the person who passed the game took the pendant.

There are a lot of people in this maker fair. It was hard, but it was good to see people enjoying the game.
