Part 1: Nintendo DS Touchscreen Color Picker | | Scyanide Chatter
I figured I'd write-up a tutorial on a little idea I had. I wanted to see if I could make a touchscreen become a color picker. Simple idea and I know it is possible. It was a good introduction into various aspects of building prototypes with an Arduino board. This tutorial is going to be broken up into two parts. First we'll talk about hooking up an RGB LED to an Arduino board. I'll be using an Arduino UNO but I'm sure most of the Arduino boards will be very similar. One last thing, keep in mind I am new to embedded development and hardware in general. So these tutorials may not be as descriptive or detailed as one would expect. Part 1.1 - Putting together the hardware Since we're building a color picker using a touchscreen part we need some way of outputting the results or rather the color that has been chosen. I could have used various types of screens but decided to keep the project simple and went with an RGB LED. I figured if I'm going to be converting an X,Y coordinate to an RGB
