There are also a few other Arduino Simulators:
Code Blocks for Arduino- limited Arduino editor and Simulator
Simulide - failed Indiegogo campaign
Visual Micro - requires MSDN?
Simulator for Arduino seems to out in front and gets upgraded at the end of each month. Latest features include a Serial Monitor, trace, auto error logging and a logic analyser is coming soon
Just came across this today, don't see any other mention of it in the forums.
Simulator for Arduino is the most full featured Arduino Simulator available at the present time (watch the latest video below).
The benefits and features of the Arduino Simulator are:
- The ability to teach and demonstrate the inner workings of an Arduino sketch
- Test out a sketch without the hardware, or prior to purchasing hardware
- Debug a sketch
- Demonstrate a project to a potential customer
- Develop a complicated sketch faster than using the hardware
