Language

based on processing which is based on java

Language (comments)

// This is a comment. It doesn't do anything.

/* This is a comment. It doesn't do anything.   Comments just make code easier for you and other people to understand */

Language (variables)

int ledPin = 13;

// This statement declares a variable called "ledPin" and sets its initial value to 13.  

// We'll use "ledPin" later to control the LED that is on the LilyPad

Language (variables)

int switchPin = 2;

// This creates a variable called "switchPin" //and sets its initial value to 2  

// We'll use "switchPin" later to read data from //a switch attached to petal 2.

Language (variables)

int switchValue;

// This creates a variable called "switchValue", // but does not initialize it

Language (delay)

delay(1000); // This tells the LilyPad to do nothing for 1000 milliseconds (1 second).

Language (digitalWrite)

digitalWrite(ledPin, HIGH); // This sets ledPin (pin 13 on the LilyPad as defined above) to +5 volts   // Setting pin 13 to +5 volts/HIGH will turn the LED on the LilyPad on.

digitalWrite(ledPin, LOW); // This sets ledPin to 0 volts   // Setting pin 13 to 0 volts/LOW will turn the LED on the LilyPad off.

Language (if while)

if (switchValue == LOW)

// if the switch is pressed

{digitalWrite(ledPin, HIGH);}

while (switchValue == LOW) {digitalWrite(ledPin, HIGH);

 delay(100);

 digitalWrite(ledPin, LOW); delay(100);        

switchValue = digitalRead(switchPin);}

Poetic message – technology possibilities

In ArTe

In the ArTe project we see technology as a possibility to introduce in our life more creativity, cooperation, and openness

Sewing as a way of seing

The LED on the lillac gown displays a beautiful yellow color to symbolize day light. The LED switches to a deep blue night color and again to yellow. Day after day. By moving my arms, jumping, walking, falling down I alter this cycle. The more I stress the less I am able to observe the cycle of life. I cannot really observe myself. I need somebody else to tell what they see on my gown LED. Beautiful or less beautiful patterns can arise while I busy myself. These patterns do not always match the lilac color of my gown.

the lillac gown (cont.)

I understand more and more the programs that govern my gown but I do not fully understand the relationships between my movements and its effects. I needed the help of both my student Hallgeir to write the code and my friend, fashion design Urd, to find my unique lilac Lilypad gown, and I need Daniela who believes in science, to observe my gown and its program to find the motivation to change. I do not fully understand the details of acceleration but I am aware I will. I know that the beautiful cycle of yellow and deep blue will come again and again.

What I learned about Arduino is …

What I take with me from today from Arduino is …

Conclusions

- What did we learn in the 2 days- Most positive- What can be improved?

- Which questions do we have?
