[prototype12_relays]
hooked up three relays, each to its own 9v and flexinol...
but there was very little movement. We tried tightening the flexinol, using lighter gauge piano wire, connecting to bigger scarier batteries, but without much success. Experimented with paper (instead of piano wire) and got a much greater range of movement.

[prototype09_shock test]
Carrie got her hands on one of those gag toys that looks like a lighter, but when you go to use it, the little bugger gives you a shock. We took it apart, but no matter what we plugged it into we couldn't hurt ourselves. We took it as a sign and decided to revisit our earlier ideas about ambient information / movement.Labels: [cm:sd]

[prototype03_microcontroller to processing]
this week we made the micro controller communicate with the computer using Processing(rather than the computer sending the micro controller information).
using the photo resistor, a series of squares dance on the screen when exposed to light. when covered, the squares stop.
this test set up basic communication and understanding of code.
next week we plan to import data into processing and make the micro controller react (basically opposite of todays video).
if the micro controller can respond to lists of data then we can begin to import live air quality updates.
import processing.serial.*;
int bgcolor; // Background color
color fgcolor; // Fill color
Serial port; // The serial port
int[] serialInArray = new int[100]; // Where we'll put what we receive

boolean firstContact = false; // Whether we've heard from the microcontroller
void setup() {
size(256, 256); // Stage size
noStroke(); // No border on the next thing drawn
// Set the starting position of the ball (middle of the stage)
xpos = width;
ypos = height;
// Print a list of the serial ports, for debugging purposes:
println(Serial.list());
port = new Serial(this, "COM3", 9600);
port.write(65); // Send a capital A to start the microcontroller sending
}
