So I got the code and circuitry to all work correctly for my "Let’s Get It On" Lamp. I am so excited to get it working on the reals.
Yet, i’m still havin some issues with the pants circuitry. Sometimes the fly signal works, others it doesn’t.
*Side note: there pants have enough batteries in them to melt through the crotch. This concerns me a bit and it could probably be wired in a more optimal way, with less batteries, but I need a break from this. FYI: Not for actual wearing!
Here’s some vid and pics of my progress.

* PWR + — +5V — red – 5V
* I2C d — SDA — green — Analog In 4
* I2C c — SCK — blue — Analog In 5

Hello, I’m from germany and me english is not good at all, but I’m building a Halloweensite and I like pumpkins and their scarving and your site was very informative and a great help for myself. I hope I’ll get as far as you’ll get with your site. Best wishes for the future.
