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.
