Arduino Open Kit Simulator ↗ All recipes
Tip: Ctrl+↵ to run
Simulate traces what the sketch would do — Serial.print output streams here, pin events show as [pin N] HIGH/LOW, delays play back at 25× speed. For real hardware output, click Download .ino, open in the Arduino IDE, and upload to your Arduino. The simulator covers Serial / digitalWrite / analogRead / pinMode / delay / tone / common loops — library calls (DHT, OLED, etc.) are stubbed so the sketch runs without errors.
