Arduino Simulator

Hi all,

Any Arduino simulator that can simulate whatever components that I have put in? So far I tried the AUTODESK CIRCUIT and there are limitations as some of the components I need (e.g. Linear actuator, 4-channel relays, slider, etc) did not provide inside. I need to verify this kind of software to verify the input and output of my project.

Appreciated if anyone of you can provide me with helpful information.

The best Arduino simulator is an Uno and a breadboard. Most of the online simulators are only good for what their designer can imagine.
