Arduino Simulator wiring checks
Generated Arduino sketch
Serial monitor
Arduino Simulator is a lightweight educational model. It helps beginners understand pins, inputs, outputs, and code flow, but it is not a full electronics solver or real firmware compiler.
Arduino Simulator drag-and-run workflow
Arduino Simulator keeps the first hardware lesson practical: choose parts, connect a known beginner circuit, run it, and see the code behind the result.
Arduino Simulator component workspace
The Arduino Simulator workspace focuses on five common starter parts so beginners can connect outputs, inputs, analog readings, and tone output without a long setup.
Arduino Simulator code and sharing
Run Arduino Simulator, inspect the generated sketch, read the serial monitor, then share the same circuit state with a URL and ShareWidget buttons.
Arduino Simulator quick guide
Use this Arduino Simulator guide to learn the first circuit loop: place a part, choose the sketch, run the simulation, then compare the code with the output.
02
Run an Arduino Simulator sketch
Switch between Blink, button-controlled LED, potentiometer dimming, buzzer, or the full starter circuit to see how pinMode, digitalWrite, analogRead, and tone fit together.
- Use Blink first
- Move the potentiometer slider slowly
03
Share the Arduino Simulator circuit
When the circuit works, use ShareWidget or copy the circuit link. The next user opens the same parts, mode, potentiometer value, and button state.
For classroom use, ask students to share one link for their prediction and another after they debug the circuit.

Is Arduino Simulator free?
Yes. Arduino Simulator runs in the browser and the starter circuit can be used without an account or install.
Is Arduino Simulator a full electronics simulator?

Which parts does Arduino Simulator support?
This first version supports five common starter parts: LED, resistor, pushbutton, potentiometer, and buzzer.
Does Arduino Simulator compile real Arduino code?
No. Arduino Simulator generates an Arduino-style sketch and simulates the expected beginner behavior, but it does not compile firmware.
Can I share an Arduino Simulator circuit?
Yes. Use ShareWidget or copy the circuit link. The URL stores the parts, sketch mode, potentiometer value, and button state.
