5. E-textiles

MY INSPIRATION


This girl makes special monsters. My inspiration is from these monsters. I really like it. I like toys and animals; they're playful things to do in life.

MONSTERS

And this account is another for toys. When you see that you say how they make it, that is the reason I like toys, monsters, and animals.

TOYS MAKER

Interactive monsters are also inspiration for my week.

INTERACTIVE TOYS by Artist Moxie Lieberman

Moxie Lieberman is an American artist based in Seattle, Washington. Her primary technique has been needle felting, but Moxie expresses ideas with embroidery, cross stitch, e-textiles, and more. She is practically never covered in animal hair.

HAVING FUN WITH ELECTRONIC!

MULTIMETER

A multimeter is a versatile electronic instrument used to measure various electrical quantities in an electrical circuit. It typically combines several measurement functions into one device, including voltage, current, and resistance. Multimeters can also measure other parameters such as capacitance, frequency, temperature, and continuity. They consist of a display screen, selection dial or buttons for choosing the measurement function, and probes or leads for making electrical connections to the circuit under test..

  • We have two wires, one COM and the other VCC.
  • COM is the minus = "GND" the black one.
  • VCC is the plus, which = red one.

RESISTANCE

A resistor is an electronic component that restricts the flow of electric current in a circuit. It is typically used to control the amount of current flowing through a circuit or to divide voltage in a circuit. Resistors are designed to have a specific resistance value, measured in ohms (Ω), which determines the extent to which they impede the flow of electricity. They come in various types and sizes, including fixed resistors and variable resistors, and are commonly represented by zigzag symbols in circuit diagrams.


  • We turn on the multimeter.
  • Then we put the switch button on the OHMS selection.
  • We put each probe on different sides of the material.
  • We read the number to know the resistance.

VOLTAGE

Voltage, often denoted by the symbol "V" and measured in volts (V), is a fundamental electrical quantity that represents the electric potential difference between two points in an electrical circuit. It is the force or pressure that drives electric charges to move through a conductor, such as a wire or circuit component. In simpler terms, voltage is the amount of electrical potential energy per unit charge available to move electrons from one point to another in a circuit. Higher voltage indicates greater potential for electric current to flow, while lower voltage indicates less potential. Voltage is essential for powering electrical devices and is a key parameter in electrical engineering and electronics.

  • We turn on the multimeter.
  • Then we put the switch button on the specific volts selection (if the batteries are 3 volts, we use 6 volts to scale that).
  • We put each probe on a different side of the battery, plus or minus.
  • We read the number to know the voltage of the battery.

CONTINUITY


  • We turn on the multimeter.
  • Then we put the switch button on the specific button (continuity mode).
  • We put each probe on a different side of the material.
  • We expect the sound (0 resistance, 0 ohms).

CIRCUITS

A circuit is a closed loop or pathway through which electrical current can flow. It consists of interconnected electrical components, such as wires, resistors, capacitors, inductors, and other devices, that work together to perform a specific function. Circuits can be simple, such as a flashlight circuit with a battery and a light bulb, or complex, such as the circuitry found in computers or electronic devices. Circuits can be classified into various types based on their configuration, such as series circuits, parallel circuits, or a combination of both. They are fundamental to the functioning of electrical and electronic systems, allowing for the control and manipulation of electrical energy to perform useful tasks.

DIGITAL SENSOR

A digital sensor is a device that converts physical phenomena, such as light, temperature, pressure, or motion, into digital signals that can be processed by electronic systems. Unlike analog sensors, which output continuous signals proportional to the measured quantity, digital sensors provide discrete, binary data representing specific states or values.


For this assignment, I started creating a bracelet with an LED light that turns on when you close the circuit.

I use the magnet to make a connection.

Tools used

  • 1 LED light
  • 1 coin cell battery (2.5V)
  • conductive thread
  • velvet fabric
  • needle
  • magnet

ANALOG (Pressure Sensor)

An analog pressure sensor is a device that measures pressure and outputs an analog signal proportional to the pressure being applied. It typically utilizes a transducer element, such as a piezoelectric material or strain gauge, which deforms in response to pressure changes. This deformation generates an electrical signal, which is then amplified and conditioned to produce an analog output voltage or current. The magnitude of the output signal corresponds to the intensity of the pressure applied to the sensor. Analog pressure sensors are commonly used in various applications, including automotive systems, industrial processes, medical devices, and consumer electronics, where precise pressure measurement is required.

  • I created a monster with LEDs.
  • You can change the brightness of the light by pressing the button.
  • My sensor is made of copper fabric, velostat, felt fabric, LED and wires.


Tools used

  • LED light
  • battery (3V)
  • jumper wires
  • resistance (velostat)
  • copper tape

ARDUINO

Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your Uno without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.

"Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.

The source is here


int led = 13;

void setup() {
  // put your setup code here, to run once:
pinMode(ledpin,OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:

SCHEMATIC

SOLDERING

  • I solder two cables together for the tail, and I also use it for soldering some parts to be more conductive.

  • The difference in this circuit is using soldering, and I use many different new things.

The result of my soldering for the first time.

It's just a toy that beeps with the Buzzer and lights with the Analog sensor.

This is my MONSTER.

I used the buzzer for the digital sensor and connected it to a switch to create a sound for one monster.

The LED is connected to the analog sensor and changes brightness when you touch the belly.
