Its just like my Diecimilia’s except that when I have a shield on it, its so much easier to change the power supply. (from usb to 9v external)
Here is a pic of my new baby along with some other boards.
The color selector is 3 linear pots that control the rgb values of a square in a window. The window also displays the rgb values. Kinda simple to make, I reused a lot of code from the etch-a-sketch sketch. I am working on my processing book, so my projects should get better.
The dot in the red pick, is me not being able to use a mouse properly, the lines on the text seem to be a problem with the font I picked.
/*
Color Selector
Takes 3 pots hooked up to analog 0,1,2 and uses them for the red green blue
values of a square.
Also displays the number for each color
