What happened to Psound?

• Well - Processing is an evolving environment -
  and new versions sometimes depreciate features.
  Psound is one of them.
• How does one know? Check the updates at
  http//processing.org/download/revisions.txt
• So, how do you get sound into your processing
  apps?
• ESS - no plug-in to play.
• Sonia - requires a plug-in to playback in
  browser.
• How do I find out how to use them?

How do I combine files?

• Ok. So youve got two apps that both work. You
  like things about both of them but how do you
  combine them?
• 1. Figure out the parts
• - variables - are any duplicated? Where are
  they declared?
• - setup - what happens in each? What combine?
• - functions - what do they do?
• - order of operations - what should happen
  first?
• 2. Take notes and start small
• - test your code every few lines you combine.
• - seek out errors, use comments to make notes.
• - save versions!
• 3. Lets give it a shot.

Lets try these two

• Buttons. http//processing.org/learning/examples/r

• And
• Bounce. http//processing.org/learning/examples/bo

• Lets see what we can get!

Things to buy for class

• The Arduino Board. (40 online, or 30 at NYU
  bookstore)
• http//www.sparkfun.com/commerce/product_info.php?
  products_id666 , http//www.arduino.cc/
• Prototyping board
• This is what you assemble your circuits on. Two
  options Jameco or Radio Shack. NYU computer
  store sells the Jameco boards, Radio Shack has
  the others.
• Radio Shack 6" board, part no. 276-174 or the
  3 inch version.
• Jameco 6" board, part no. 20722 or the 3
  inch version.
• Resistors, LEDs, and other things
• 1K Ohm Resistors, 1/4 watt may be available in
  the lab
• 10K Ohm Resistors, 1/4 watt probably not
  available in the lab
• 220 Ohm Resistors, 1/4 watt probably not
  available in the lab
• 22K Ohm resistors, 1/4 watt may be available in
  the lab
• LED's available in the lab
• Switch
• Variable resistor. The NYU computer store
  carries Flex sensors, which are good fun. Also
  consider a potentiometer or solar resistor.
• Tools recommended
• miniature Philips/flathead screwdriver,
  Jameco 127271
