A motion sensor (or motion detector) is the linchpin of your security system, because it's the main device that detects when someone is in your home when they shouldn't be. A motion sensor uses one or multiple technologies to detect movement in an area.

  • Use motion sensor and when feel someone / sound (photosensor) the garment moves.

Arduino

Arduino's language is the C code, it has a UART/USART to connect to you computer. Arduino can work connected to your computer where you can programme it or it can work by itself like a mini computer once you have saved your programation in it.

Arduino Vocab.

  • Loop: Code in Repetition (only need 1 line to do man things)
  • Setup: Code do 1 different things per lines.
  • Variable: Name of Box with information and type of information (for memory)
  • CHAR: 1 letter
  • STRING: More than 1 letter (word, phrase)
  • INT: Number
  • FLOAT: Number with decimals
  • Same as: ==
  • Serial.begin (115200): Speed how it connect to my computer
  • Serial.println (NAME): Show you what we programmed before
  • AnalogWrite: let read value for speaker
  • Tone: Wich pin, wich velocity (PIN, Hz)
  • NoTone: Wich pin (PIN)

Sound Actuator - Speaker

  • You can measure the frequency of plants, sun,..., and convert them into sound.

Code for sound

void setup() { 
  // put your setup code here, to run once: 

} 

void loop() { 
  // put your main code here, to run repeatedly:  
  tone (3,440);
  delay (200);
  noTone (3);
  delay(1000);

}

Code for shape memory

void setup() {
  //Initialise pin 1 for output
  pinMode(8, OUTPUT);
}

void loop() {
  digitalWrite(8, HIGH);   // On - contract the flexinol
  delay(2000);                       // wait for 2 second
  digitalWrite(8, LOW);    // Off - let the flexinol relax
  delay(4000);                       // wait for 4 seconds
}
