For Patrick, check this sample program for your purpose

//sample progrma with shiftresiostors and photosensors
// this program is very basic. you can use one photosensor and upto two shiftresistor so that you can control upto 16 LED with only 3 digital pins of Arduino

//connect photosensor to analog pin 0
int analogData0;


//Pin connected to ST_CP of 74HC595
int latchPin = 8;
//Pin connected to SH_CP of 74HC595
int clockPin = 12;
////Pin connected to DS of 74HC595
int dataPin = 11;

//regure variables
int RadomVal0;


void setup(){
//Start Serial for debuging purposes
Serial.begin(9600);
//set pins to output because they are addressed in the main loop
pinMode(latchPin, OUTPUT);
}

void loop(){
//read data from analog pin 0
analogData0=analogRead(0);
//scale down the value form 0-1023 to 0-255 which works with shift resistor.
analogData0=analogData0/4;
//put a randomize value into variable RadomVal0 this value take form "0" to "the scaled value" so that the new value still reflect the photosensor's value
// this code is optional
RadomVal0 = random(0,analogData0);
// tell shiftresistor to start
digitalWrite(latchPin, 0);
// actual data
shiftOut(dataPin, clockPin,MSBFIRST, RadomVal0);
//if you have second shift resistor. elase // and activate the program
//shiftOut(dataPin, clockPin,MSBFIRST, RadomVal0);
//tell shiftresistor to edn
digitalWrite(latchPin, 1);

// duration of the led light
delay(1000);
}

/*

Arduino Daisy Chain 03

I finally fined a way of daisy chain Arduino.

Prepare two Arduino

Connect USB cable to one of Arduino

Put one side of a wire to 5V of the Arduino that USB is connected to.

The other side of the wire go to vin of the other Arduino.

Connect Tx to Rx of the other Arduino.

Connect Rx to TX of the other Arduino.

motion sensor information

Since we have two different motion sensor this link will help to use the motion sensor which I did not make tutorial.

Check below link to see the first motion sensor tutorial.

http://art-research2010summer.blogspot.com/2010/06/sensor-motion-sensor.html

http://www.eathertons.com/blog/?p=73

The most different point of these two motion sensor is that the colors of the wire are different so that we need to change the connection of the wire and the motion sensor that is talked in the link require a resistor.

I think it is a good idea to reduce the delay  time in a program that was introduced in the link so that the motion sensor works more ideally.  Also I preferred to use a more higher resistor that the resistor that was used in a tutorial so that you can get more good data from the motion sensor. 

 

Isadora setup

Serial In watcher will control everything, so that Arduino can control everything.

Somehow Isadora's picture player does not work properly. Even I send a value 0 to turn off visibility, it does not work. Only wave generator can controll on and off.

 Also "Gate" does not work for picture player.

This program is specifically designed to communicate with Isadora.

You can use this program as a switch in Isadora.

Prototype of a circuit for my work

LEDs are connected in parallel and each one is controlled by NPN transistor and transistors are controlled by 8bit Shift resistor.

 I can use external power supply for LEDs.

Program

You can use sample program "Blink"

You just need to change 

int = 13;

to

int = 2;

Today's work

I made a several new drawings.

Arduino daisy-chain

I tried to connect Arduino to Arduino.

I connected pwm pin of Arduino(1) to analogPin of Arduino(2) to get a variety of values.

But I could get only on and off.  It was not useful, since it is potentially break Arduino.

Shift resister is more useful to increase the number of pins more than daisy-chain.

7 segment with Shift Resistors

I did a test of controlling 7 segment with Shift resistor 8-Bit - 74HC595.

I finally control two 7 segment with two Shift resistor 8-Bit - 74HC595.

Tutorial

Shift resistor 8-Bit - 74HC595 is very useful since Arduino have only 13 digital pins we may need more pins to make a more complex controller.

7 segment is one of a example that need a lot of pins to control.

So that I will explain Shift resistor 8-Bit - 74HC595 with two 7 segment.

Requirement

Shift Resistor 8-Bit - 74HC595

Two 7 segment

A lot of wires

14 220Ohm resistors

Breadboards(At least you need one large  Breadboard) I use one  Breadboard and two small  Breadboard.

Arduino

Arduino program

computer with USB

Calculator (you need to change decimal to binary)

Circuit

latchPin is 8.

clockPin is 12.

dataPin is 11.

When you send a value with ShiftOut, the value which transformed into
a binary data will conrespond to the red pin(Q0 ~ Q7).
Since this is a 8 bit shift resistor, the range of the value will be 0~255.
(2x2x2x2x2x2x2x2)
For example, if you send a value 96, it will transformed to 011000000.
Since number 0 means off and number 1 means on, in this case Q6 and Q5
will be HIGH.

This is a really great tutorial for beginner and and very useful. 

Practical Tutorial of How to make Aii (Arduino + Wii Nunchuk) and use it

This is a tutorial of How to make Aii(Arduino and Wii Nunchak).

This exercise enables you to connect Wii Nunchuk to Arduino.

You will also learn how to connect Aii to Isadora and how to send a OSC data over the Internet(Wi-Fi).

Wii Nunchuk is a great tool for us. It has 7 different input device(two button, two potentiometer like function and one XYZ accelerometer)

Having an Accelerometer is really great, because the cost  of accelerometer is from 19.95 to $39.95.(SparkFun.com) However, if you order Wii Nunchuk from Amazon.com, it costs only from $3.25 to $19.95. 

I connect Nintendo Will Nunchuk to Arduino and made Aii.

The program was based on the information of http://www.windmeadow.com/node/42

I added little more cords so that it works with Isadora.

To make a circuit, I referred http://todbot.com/blog/2007/10/25/boarduino-wii-nunchuck-servo/

For the information of OSC transmission with Isadora, I referred http://vjskulpture.wordpress.com/2010/01/14/basic-open-sound-control-osc-isadora-mac/

Program

You can use a program from http://www.windmeadow.com/node/42

But you have to change the function of void print() in the program to following.

void
print ()
{
int joy_x_axis = outbuf[0];
int joy_y_axis = outbuf[1];
int accel_x_axis = outbuf[2] * 2 * 2;
int accel_y_axis = outbuf[3] * 2 * 2;
int accel_z_axis = outbuf[4] * 2 * 2;

int z_button = 0;
int c_button = 0;

// byte outbuf[5] contains bits for z and c buttons
// it also contains the least significant bits for the accelerometer data
// so we have to check each bit of byte outbuf[5]
if ((outbuf[5] >> 0) & 1)
{
z_button = 1;
}
if ((outbuf[5] >> 1) & 1)
{
c_button = 1;
}

if ((outbuf[5] >> 2) & 1)
{
accel_x_axis += 2;
}
if ((outbuf[5] >> 3) & 1)
{
accel_x_axis += 1;
}

if ((outbuf[5] >> 4) & 1)
{
accel_y_axis += 2;
}
if ((outbuf[5] >> 5) & 1)
{
accel_y_axis += 1;
}

if ((outbuf[5] >> 6) & 1)
{
accel_z_axis += 2;
}
if ((outbuf[5] >> 7) & 1)
{
accel_z_axis += 1;
}

// This is a section that is actually modified.

Serial.print(1,DEC);
Serial.print (joy_x_axis, DEC);
Serial.println();

Serial.print(2,DEC);
Serial.print (joy_y_axis, DEC);
Serial.println();

Serial.print(3,DEC);
Serial.print (accel_x_axis, DEC);
Serial.println();

Serial.print(4,DEC);
Serial.print (accel_y_axis, DEC);
Serial.println();

Serial.print(5,DEC);
Serial.print (accel_z_axis, DEC);
Serial.println();

Serial.print(6,DEC);
Serial.print (z_button, DEC);
Serial.println();

Serial.print(7,DEC);
Serial.print (c_button, DEC);
Serial.println();

Serial.print ("\r\n");
}

// Encode data to format that most wiimote drivers except

Isadora

You do not do something special for Isadora but you have to make a lot of "Serial in Watcher".

Check below again to know how to do it.

http://art-research2010summer.blogspot.com/2010/06/tutorial-01-isadora-and-arduino.html

You need 7 "Serial in Watcher" to get all of the benefit of Wii Nunchuk

All of the "Serial in Watcher" need ideal number to identify each other.

Program for Isadora's Serial in Watcher(double click and open a window)

Serial in Watcher 1

"1"

StickA: integer = 4 digits

Serial in Watcher 2

"2"

StickB:integer = 4 digits

Serial in Watcher 3

"3"

Acc1: integer = 4 digits

Serial in Watcher 4

"4"

Acc2: integer = 4 digits

Serial in Watcher 5

"5"

Acc3: integer = 4 digits

Serial in Watcher 6

"6"

ButA:interger= 4 digits

Serial in Watcher 7

"7"

ButB: integer = 4 digits

Go to the OUTPUT and Setup Serial (choose Serial such as COM4 Speed 9600) and check Enable Serial 

You can play around with Aii to see how these value will change.

Make "OSC transmit"

Setup IP address of the computer that you want to control and connect the value of the "OSC transmit" to the "Serial in Watcher" which you like.

Setup your another computer

If you do not know how to check your IP address, see my blog post about Arduino Server (below address).

http://art-research2010summer.blogspot.com/2010/06/arduino-ethernet-shield.html

Run Isadora in your another computer(in my case it is a Laptop).

Make a OSC listener, that it!.

You will get a value and you can use this value for anything that you want to use.

I use "Calculator" to adjust a value and connect it to "Dot" size.
