Pin Visualizer
Debug your code with ease! The pin visualizer is a simple block of code that tells you what pins fire when. Check your programming work or reverse engineer a shield! Voltage on analog pins and logic state on digital pins are displayed. The TouchShield only uses pins 2 & 3 (with power) which leaves 6 analog pins and 12 digital pins free for use. Signals are followed in real-time.

I’ve uploaded the rest of the TouchShield’s built-in commands are over at the function reference wiki.
This clears up serial communication quite a bit. thanks. BTW, i like how the analoginput text color changes as voltage changes. Very cool app. I think i’ll use it as a springboard for my project.
