Step 1: Pixel Flip

This is an Auto Flip Art Wall that combines analog and digital with a Flip Book as the motif.

Step 2: Background

The project was created because it wanted to maximize reflections based on various materials and express them to people. It was developed to express the fascination of reflections that we see in our daily lives.

The first question we thought about as how to express a variety of reflections. We've taken a lot of form into this idea.

We came across an animation of a flipbook. Unlike the hand-operated analog flipbook, the auto flipbook with the motor was able to experience analog in digital. When the flipbook came back, I thought it could be interesting to use a variety of materials.

We also thought about how to use flipbook animation more. The flipbook that we found was a square, but the structure of using only one flipbook to animate through it was common. I thought, well, how about using several flipbooks to create a wall with interactive elements.

And not just the feeling that the wall is moving, but if we use it to express the image that we want, we can create an interesting experience that allows us to feel both analog and digital as well as reflections of materials.

We worked with these goals.

- Combination of analog and digital

- Utilize Flip Book structure

Step 4: Control Board Selection

Arduino decided that there were many open source and libraries available, so we could use them easily, and that processing is also using the same language, so there would be no problem with compatibility. We then checked the requirements to proceed with this project.

- Light: Strong lighting should be used to maximize reflections of materials. - Material: Material that can show reflection of different light. - Flipbook Structure: For the animation we want, use a step motor with free-angle control. - Aduino: Initially, we needed Aduino Mega, because we wanted to control all the motors with just one Aduino.

However, because processing is communicating with one Aduino, as other Arduino was needed, there was a need for a way for the data sent by the processing to be sent to a large number of Aduinoes

This resulted in the use of a DPLC485HCA module with RS485 communications that enable 1:N bi-directional communication.

The processing then transmits the data to a single Master Aduino (Master Aduino) and Serial communication, and the Master Arduino establishes the communication between Master-Slab using the DPLC-485HCA module.

Using the data received from Master, Slave Arduino controls the angle to which each motor is to be turned, providing a visual representation of the result of the image being processed with the movement of the motor.

Step 5: Select Flipbook Material

Because the project wanted to maximize reflections according to different materials and express them to people, it chose four different materials with different reflections of light and different materials depending on the angle.

- hologram: It is the most luminous material because of the intense reflection of light.

- splange: It is a material that reflects multiple spangles at a glance to show different reflections.

- Metal: It's light-dissipating.

- Velvet: A material that varies in color with light due to its gloss.

To express the above materials through motor control using processing, we changed the picture to a black-and-white picture using a gray-colored filter, measured the minimum and maximum colors of each pixel by pixel adjustment, divided each pixel into four sections of color, and sent each pixel value to the motor to represent the representation of each section according to the rotation of the motor with hologram, spangles, metal and velvet material.

Step 6: Structural Design and Prototyping

What to consider when determining the structure:

- Ensure each other's motors are free from collisions

- The flipbook should stop at the desired angle

- Ensure there is no interference between the flipbook and the outer frame

We used a relatively easy-to-process, acrylic 3T, and we decided to use a metal profile because of the cost and availability of acrylic plates.

The structure consists of 5*5, a total of 25 rectangles. Each acrylic plate was then cut using acrylic cutters to any size desired and then assembled together using hinges and screws.

The play left between the acrylic plates was used as a place to protect the cables without collisions with each other's motors.

Step 7: Step Motor and Structural Installation

We used 25 step motors.

- Use two step motors for each aduino

.- Install step motors in the center right of squares

- Screws are used to secure the step motor.

- Cappling is used to connect the new main bar to the step motor

.- Connect a wooden rod outside the Shinjubong and connect the material with a clamp.

Step 8: Install Internal Structure

Step 9: Button Installation

We chose different keyboard buttons for each image to maximize the interactive effects while using flipbooks. When the user clicks on the keyboard, the motor and flipbook operate and keyboard-specific images appear.

Step 10: Wiring

The square used 25 step motors, 14 aduino and 14 a DLC-485HCA. Processing and Master Arduino must be connected.

We've connected it using a breadboard. I tried to split the + and - parts on the breadboard and connect them to the motor to provide enough power.

6. DPLC-485HCA 6 is GROUND of communication, connecting with GND line from Arduino in BREADBOARD

- COMPUTER POWER SUPPLY

1. Connect the + and- of the BREADBOARD to the + and- of 5V of the COMPUTER POWER SUPPLY

Step 11: A Power Supply

Because processing works only when connected to the computer, we used a USB HUB, which is not low on power. However, the only source USB HUB has insufficient power to connect one of the two motors connected to a single aduino to a 5V SMPS so that it does not run out of power.
