10. E-Textiles and Wearables II

We had the opporttunity to put in practice again our skills in e-textiles and wearables. This time was different, we had the previous knowledge to improve our prototypes. So this week we saw: Different types of outputs, how do we control them and what are transducers.

To Use

  • LEDs
  • Neopixels
  • Sound
  • Fabric speakers + amplifier circuits/code
  • Powering circuits
  • ATtiny

Wearable II.

Speaker with latex

Circuit

The clue here is to have our embrodery with two types of thred, a normal one and other conductive. And that they have a circular or triangular shape with spiral lines.

What you need: 1. Speaker 2. Amplifier 3. Bottom battery 5V 4. Resistor 100 ohm 5. Magnets

Speaker Code

void setup() {
  // put your setup code here, to run once:
  pinMode(A0,INPUT);
  Serial.begin(115200);
}

void loop() {
  // put your main code here, to run repeatedly:
  int speakerPin = A0;
  analogWrite(speakerPin, 255);
  tone(11,440);
  delay(200);
  noTone(3);
  delay(1000);

}
