Yesterday, while Kara was working on blogging and researching supplies that we need for this project. I spent a good chunk of time understanding RGB LEDs this meant frustrating trial and error.
As Kara mentioned, I was using 3 analog sensors: 2 potentiometers and 1 pressure pad to control each of the color channels individually to create a range of light colors. Because I had never worked with an RGB LED, I couldn't get it to work at all and every time I changed something in the circuit, the LED would light up in a different color (assuming that the circuit worked power it).
Luckily after asking Colleen and finding this website: http://hertaville.com/?p=168, I understood that LEDs can have either a common cathode or common anode. I assumed that my LED had a common cathode and it wasn't so.
I got it to work! I wasn't able to spend too much time playing around with it to look at the pretty lights but I have pictures:
As you can see this light is a bluish green.
The crammed mess that I made for myself.
I look forward to using my nerd skills to make this project work. (Muxing... watch out)
