We’ve released the first prototype of one of the most requested Arduino Pro IDE features: the Arduino Debugger!

Key features include the ability to:

• Execute your Arduino sketch step-by-step while it’s running on your Arduino board!
• Pause your sketch execution placing breakpoints.
• Inspect variables values during execution.

Initially supporting SAM D21 boards, the Arduino Pro IDE Debugger is available for Windows, Mac OS X and Linux64.

You can try the Arduino Debugger as part of the latest Alpha preview version for the Arduino Pro IDE. More details will follow soon!
