MAKE: Blog: Visualize all of the pins on your Arduino in real-time

Visualize all of the pins on your Arduino in real-time

Here's an interesting use of the TouchShield (which we've covered here before on Make) for the Arduino controller that serves as a pin visualizer that lets you check if all of your I/O pins are working correctly as programmed and displays voltage on analog pins and logic state on digital pins. All signals are followed in real-time with this code that is downloadable from the project link below.
