White LED Box
I wrote up a blog entry with much great detail and pics but didn’t want to include all of that here as it would be reruns for most of the people in class.
Here’s my first iteration of the LED enclosure assignment.
And here is the second iteration, now incorporating sound.

I was out of town til Wednesday this week, so when I found out we had an assignment for Thursday’s class my main concern was just getting something presentable. I was surprised at how quickly I was able to get a working prototype with some cardboard and the wire wrap tool. Thankfully everything was laid out neatly with the header pins so I was able to test the code and ensure there weren’t any short circuits.
The code was actually the portion that took longer than I assumed it might. Making the whole series of LEDs do something was simple enough with a for loop, but trying to do any sort of pattern proved a little more counter intuitive. Using the fade code from Monday’s class I was able to add some variety to that simple sequence of LEDs turning on into something different for the “waking up” function of the box.

1.What was surprising about making your project?
Instead you using multiple separate LEDS I used a single RGB LED, I assumed that the methods for fading and flashing would be almost identical to single LEDS and I was mistaken. I learned that different colors are activated and are visible in different amount and trying to arrive at a single suitable color combination proved to be interesting.I thought it would be simple to come up with switches for transitioning between “moods” but the potentiometer I used is quite finicky. Instead of moving smoothly between each mood it is hard to determine how to be in specific sections of fading,flashing A and flashing B.

Surprises for this process: it wasn’t too difficult to get the LED’s working. Working with Mike Susol, we both had a sense of satisfaction with this revelation especially with the “sleeping” state. We both hadn’t worked with brightness before.
What was difficult was “perfecting” the project. Putting ‘for’ loops inside the else, else if statements — and timing the pauses between the states accurately.
Taking arduino to the ‘next’ level jumped me to understanding a bit more. There was an additional satisfaction in making a complete project. Also, the several ways our code can be written was also seen.
I hadn’t ever seen Arduino as an art medium previously: I’d always only concentrated on just trying to make the code work.

This project was surprising in all aspects. Having left the practice of making projects every week since the brake reminded me that it is practice that makes perfect. It is important to keep these skills current. The delay threw me off! having to rename it so it can be checked and not interfere with other commands was the most unexpected challenge this project brought to me. Also, I forgot how fun it can be to find beautiful colors rather than have the cycling rainbow effect. This project brought me back to my earthy roots, I am glad to incorporate sand and its other state silicon.
