All programming of the Interactive Puppet Theater was done only in two Arduinos rather than using an ordinary computer. It was much more difficult than I expected because the program should work well with other hardwares such as an MP3 Player, six servo motors and lots of LED. In addition, our project is not a simple input and output device, but has several inputs and outputs with more than 30 steps.
Tasks that easy but took several hours were:
* Using servo motors - controlling speed and positioning
* MP3 Player hacking - timing of signal and using Reed relays
The hardest tasks that I didn't want to do at the first time was:
* Since normal Arduino board has not enough input/output pins and memory, I had to use two Arduinos so that I divided the program into main Arduino which follows steps of story and processing each steps, sub Arduino which executes output.
These nails were given by Todd Holoubek who said they would solve the problems when our team was stuck.
Sometimes, I couldn't figure out what's wrong with the hardware, however, the problems turned out so easy things. Here are some points:
* Don't use a breadboard for a final product. Its holes are getting looser so that connections will become unstable.
* Don't trust a terminal which is used for firmer connection to a breadboard.
* Check a common ground value if you use several boards.
* Make a quick-test board and prepare programs for testing LEDs, sensors and other electronic parts.

My project of the ITP Winter Show 2006 was the Interactive Puppet Theater. (pics)
Day 1
Final rehearsal. There was some problem with a MP3 player at the last minute of the show preparation, but it worked well in the show.
 
 
 
Show for children. One of kids saw the show four times continuously.
Show for my adviser Daniel Rozin and his kids
 
 
 
children's participation
Day 2
Add balloons!
 
 
 
Second day show
After the Show with Jaewook, exhausted but HAPPY!
