We unveiled the Robot Hacks project at our Seacoast Robotics meet-up last week, and much of the time was spent trying to figure out how to make a tinfoil capacitive sensor work. We had no luck that night and we've been troubleshooting for the past few days, but we're slowly figuring all of this stuff out.

This evening, I rigged up a capacitive sensor and ran a program that triggered a touch to turn on an LED. The LED in this video is on the Arduino board, but it's pretty hard to miss. This means we're one step closer to creating our angry robot cat that does NOT want to be touched! 

What I really love about this process is how the challenge keeps drawing me back and I keep learning so much more. The problems that I saw a week ago are gradually unraveling themselves as I am getting more familiar with how things work.
