Prototype/Outcome

I decided to make a fan that has its' desire, and it communicates with the morse code. Since the wind morse code is very subtle, humans should feel the breeze carefully, and you will understand what it says: the long wind indicates a dash(-), and the short wind means a dot(.). It will keep sending the signal till you show the color it wants.

The digital tools used were the color sensors on the Arduino Nano BLE and the relay. The color sensor requires the individual value of red, green, and blue. And it allows the creation of an infinite number of different colors, just like a human desire. Also, a relay was used to create the long and short wind; turning on and off was considered so that it had a binary pause in between the signals. Even though the power source is binary, the motor takes some time to stop rotation after the call. This allows the different softness of the winds as well.

The physical supplement is the set of cards, including R, G, and B color cards and the instruction of morse code. The instruction card helps people who are not familiar with the morse code could easily understand the signals. Also, the color cards are made not only for accessibility but also for affordance. It will be easier for the listener to know what it wants is the color among these three.
