Lecture takeaways by Liza Stark

--> electricity , the 3 VIPS: voltage, current, resistance
--> we can change resistance in 3 ways: distance, surface, contact
--> difference between digital sensors = on/off 1010101 AND analog sensors (variable resistors offering a range of values)
--> physical swatch exchange
--> intro to Arduino: the IDE, the different boards, code functions

Electronic basics

--> Experimenting with digital and analog sensors, I tried the quick and dirty sensors for both:

--> Experimented with circuit

--> Experimented with digital sensors

--> Experimented with different conductive fabrics

Experimenting with Arduino

--> eTextile kit

--> turn a led on

--> make a led blink

--> make a led fade

--> make a button (digital switch)

--> measure an analog sensor

--> followed the workflow tips to test an analog sensor

--> measure the analog sensor with a multimeter

--> measure the analog sensor with arduino analogRead.sketch

Test & fail

--> I was not able to make the analog sensor + led work, because I didn't have 10kOhm resistor in my kit. It took me 2 hours to understand what wasn't working in my circuit. Good lesson here, don't UNDERESTIMATE THE RESISTORS.

--> I also tried making 2 LEDS light up using one breadboard, but did not figure that out. I will experiment more on that. Probably linked to the resistors I'm using.

Wearable project

--> Inspired by the "Embrace Me" hoodie by Studio 5050, conductive fabric on the chest of the hoodie closes a circuit when two wearers hug, causing a pattern on the back of the hoodie to light. I'm thinking of the same idea of a closed circuit, on a dancer's bodysuit, with parts of conductive fabrics randomly embedded on the suit, and when dances touch it lights up leds in the back. Dance is about movement individually, and how you can balance your body with other bodies. Touch and weight in contemporary dance are central. The lights would enhance the tension created when 2 bodies touch.
