Session 1

With Denis de Bel. Quick link to wiki

Building a module

We built a synth that can receive samples

Session 2

Workshop at De Player with Olli Aarni and this is pad

My random notes

• Open string phenomenon: Something that seems to have limited options but actually has more (one hand on the string and one hand on the pitch)
• When you don't control your instrument, how can you still effect it (like the raindrops falling on tin- you don't control the rain but you can control the material it lands on for example)
• Natural generators (example: the lava lamps next to each other, each with different number of bubbles)
• A thought- what make a certain sound iconic? like the kindergarden sound- kids screaming+running on the ground+the voice of the teacher= the kindergarden sound. Like a recipe, all these sound together create a complete other sound and they can function on their own as well.
• A name- a short sound that you were trained to respond to.
• In language- sound that are toward the inside (me) and sounds that are toward the outside (you, he, she)
• I want to expand on- structure of languages.

Session 3

Americ: the Arduino environment is pretty limited because every module can do a limit amount of actions. The coding language commands a lot of the time contain a lot of command inside.

Simpler way to upload a sample

In terminal:

• go to the folder where the files are
• pull from git if needed
• use sox with this command: ./<name of sh file> <name of wav file> (this runs this code on the sound file)
• this create a sample.h from the sound file
• Now you have a new sample.h file

Arduino environment

serial.begin(9600)- the number is number of symbols in a sec.

serial.print- will show the output

void loop(){ everything inside that will loop

delay(1000)- will give a delay of 1 sec

In class

• We reviewed some loop commands in the code
• We tried to affect each other's modules with a code in this files:

• Link to Arduino 101
• Link to Arduino 101-LFP

Session 4

Monday+Friday sessions The Friday session really helped with some deeper understanding regarding how to work with the module.

At home

Recommended set for deep thinking by Helene Rickhard

I tried to do some visual stuff connecting my module to processing through the computer (because Processing is a more "visual" coding environment). The main issue was transferring the information we are getting from the Arduino to Processing.

References for visuals using Arduino-Processing connection

These are the links I used

General- connecting between Arduino and Processing

• Explanation about working wit electronics and processing
• Example for transferring info from the Arduino port
• About the command Serial.read

Serial port

In the Processing code you need to be "on" the same serial port that the Arduino is running on

• This is an explanation how to find out through Terminal

In the Processing code you need to chose the port number in this line-Serial.list[number-of-port] myPort = new Serial(this, Serial.list()[11], 9600);

Adding this line println(Serial.list()); to the processing code will show the lists of port and than you can find out which one you should be on.

• About the command Serial.read

Converting text input to number value (int)

• Turning a string from Arduino to an Int(converting the text you get to an actual number)
• Turning a string from Arduino to an Int 2
• Transferring the data using Bytes (I didn't really get it)
• This worked best for me regarding making ints from Arduino

Multiple inputs

The problem that I have right now is that my code doesn't know how to get different inputs from the Arduino (A0, A1, A2). I think this video will help me:

Session 5

Workshop at De Player with Olli.

Concepts

• How do we explain modules? There is so much backend output and input that no one is seeing- what if we make it be seen and heard?
• Regarding my reading in methods- in Matthew Fuller book there is a critic regarding not giving enough significance to the components of the software and just to general concept and philosophy of it.
• Visual ways of representing sound- what can be new? or visual ways to represent the "backend"
• Regarding the manual- what if every manual look differently? like the output of the Arduino or something
• Giving a sound an image- 1+1+1 (sound+hex+space= shape)

Visuals, video art and other crazy ideas My wish is for my module to be more on the visual side of things. I would like the module users to generate some kind of image with the module input and for the process of input to output to be somehow represented in the visual-

Working on the module

We were given a restriction that we can't use a computer with our module. So I can't use processing. Aymeric, Dennis and Michael figured out a way to use the Arduino library TV.out which allows to output video signal. It is a bit of an old library and and there is not a ton of information about it online.

TV.out tests

So this library is pretty old so not a lot of info about it online but you can find some.

First I try drawing pixels across the screen using a loop (actually two loops)
