8. Wearables

Week 08 _ light again

describe what you see in this image

The eighth week started with depression like the fifth. I believe that this comes from the topic discussed and realized during the week. Or because the field is too complex and I don't have the necessary knowledge. Complicated, but...

My experience

This week we studied electricity and electrical circuits. The course E-textiles given by Liza Stark was quite explicit. But when you don't know much about the field, you think you won't succeed. TIn order to carry out the tasks of this project, I asked for the help of a student at the university where I work as a lecturer. His name is Gheorghe Virlan. He is a fourth-year student and knows a lot about electricity and circuits.

Inspiration for individual work

The Internet is an inexhaustible source of ideas. Analyzing the multitude of images, you realize that the world evolves very quickly. You are no longer surprising anyone with smart clothing products. Here you can see the access links to my source of inspiration: 1, 2, 3 and 4

After several attempts, I decided that I will make circuits with light sensors and carbon monoxide detection sensors. These circuits are planned to be inserted into clothes.

The first experiment - circuit with carbon monoxide detection sensor

The carbon monoxide detection sensor circuit is a medium complexity circuit. The use of such a circuit allows the detection of a large amount of carbon monoxide when entering an unventilated room. To be able to do it, the following components are needed:

With Gheorghe's help, we managed to test the circuit. Initially I assembled the supply elements and wrote the code for this circuit.

This is the code for the carbon monoxide sensor circuit. It was written in the C++program.

int Sensor = 2;
int Sunet = 1;
void setup() {
  pinMode(Sunet, OUTPUT);
  pinMode(Sensor, INPUT);
}

void loop() {
   // citim datele de la sensor
   if (digitalRead(Sensor) == HIGH) {
      digitalWrite (Sunet, LOW);
  }
   if (digitalRead(Sensor) == LOW) {
      digitalWrite (Sunet, HIGH);
  }
}

Then I checked the circuit.

Then the circuit elements were securely joined together.

The circuit diagram with the carbon monoxide detection sensor is shown below

Then I created an organza flower, which will serve as a brooch. A special pocket was created for the circuits in which almost all the elements were hidden. The sensor and the buzzer remained unhidden. Also, the wires that connect to the battery remained on the outside. At the end I sewed a pin to hold the brooch on the coat.

The brooch was placed on the clothes, and the battery was hidden in one of the three pockets of the jacket. This is how the integrated circuit in the jacket works.

This is what the final picture looks like.

The second experiment - circuit with light sensor

The light sensor circuit is a medium complexity circuit, too. Light sensor circuit is a circuit that turns on the lights when it gets dark. Just like the first experiment, we started by finding the necessary elements.

With Gheorghe I created the initial circuit and wrote the code.

This is the code for the light sensor circuit. It was written in the C++program, too.

int Sensor = 2;
int Led = 1;
void setup() {
  pinMode(Led, OUTPUT);
  pinMode(Sensor, INPUT);
}

void loop() {

   if (digitalRead(Sensor) == HIGH) {
      digitalWrite (Led, HIGH);
  }
   if (digitalRead(Sensor) == LOW) {
      digitalWrite (Led, LOW);
  }
}
Then the circuit elements were joined and checked

The light sensor circuit diagram is shown below

Then I started the process of creating the setting in which the circuit will be inserted. Various crocheted samples were selected as elements of the decor. These were placed and sewn on a dark colored felt.

Then the circuit was placed on the decor and assembled by decorative stitches. Of course, the light detection sensor and the connecting wires to the battery remained outside.

Finally, the decoration was placed on the jacket through decorative stitches. If necessary, the decoration can be removed and placed on another product. The battery was hidden in the side pocket of the jacket.

And this is how the circuit worked.

But this is the final picture of the integrated circuit jacket.

Conclusions

Wearables is a very complex topic. It would take at least two weeks for her to be able to do a good job. Good luck everyone!!!
