====== WEEK 9 ======

====== E- TEXTILES & WEARABLES II ======

Charlie´s and mine final project, is to make a portable crib that rocks the baby to sleep. For that rocking system, we need a motor, for me that´s kind of new, so I began trying with the basics so this week´s project serves as a first reach for the final project movement part.

This week I decided to experiment with some soft circuits, by generating one of the many parts of my final project. I need to generate movement, so I'll use a DC motor, connected to a LilyPad Arduino. The circuit will be created from conductive threads. Here's the complete BOM:

  - 2 3.3 volts coin cell batteries
  - 1 LilyPad Arduino
  - 1 L298 module for Arduino (H-bridge)
  - 1 DC motor
  - 1 soft sensor (it's a variation of the stretch sensor I made during week 5)
  - 1 5 kOhm resistor
  - Conductive thread
  - Some jumpers
  - Copper coated Vinyl

The idea is that the speed of the DC motor will change depending on how much pressure is being applied to the sensor. Here's the code:

<code>
int in1 = 9;
int in2 = 10;
int enable = 11;
int soft_sensor = A5;
int Lectura;

void setup() {
Serial.begin(9600);
pinMode(in1, OUTPUT);
pinMode(in2, OUTPUT);
pinMode(enable, OUTPUT);
pinMode(soft_sensor, INPUT);
}

void loop() {
digitalWrite(in1,HIGH);
digitalWrite(in2,LOW); //DC motor is constantly ON);
Lectura = analogRead(soft_sensor); //Read soft_sensor
Lectura = map(Lectura,0,1023,0,255); //Turn analog readings to PWM
analogWrite(enable,Lectura);

}
</code>

I used the conductive thread to generate the ways connecting all the components. In general, I connected my circuits through the top face of the fabric, but when I had to connect two points through a way which would intersect another, I used the bottom face of the fabric.
