I would like to start the development of some basic Arduino projects but I don't own an Arduino board yet. Is there a way I can write my code and emulate/test it using a desktop computer so after my board arrives I just have to upload and run my project on it?

There are a whole slew of Arduino simulators out there, many free, and some paid products as well.

  • The CodeBlocks Arduino development environment includes a free Arduino simulator, still under development but functional.
  • Simuino simulates the Arduino Uno and Mega pins - not a pretty-looking realistic simulator, but it works.
  • The Python based Arduino Simulator is another option, that plays well with the official IDE
  • Virtronics Simulator for Arduino looks promising, but I don't see why I would pay $14.99 for it, when I could buy one or more actual Arduino clones for that price

Many other Arduino simulators are out there if you search, and new ones are being announced, even crowdfunded, all the time.

as a note, those are not emulators but simulators, the most important difference is that it does not run the code on a AVR virtual machine (like what qemu does), but binds the Arduino functions to native code. So basically they won't be able to run native AVR stuff and register/timer behavior will not be the same as on real AVR hardware. See the difference well explained in that answer. It is, though, theoretically possible to emulate Arduino Due code with qemu. –  zmo Mar 13 '14 at 19:33

You "don't see why [one] would pay $14.99 for it, when [one] could buy one or more actual Arduino clones for that price"? I can tell you why: because the hardware doesn't have a built-in debugger with the features that can be provided by a simulator. –  R. Martinho Fernandes Jul 16 '14 at 22:16

The Arduino Simulator piqued my interest, but unfortunately appears to have no files related to it on the sourceforge site. Am I missing something, or has it become deprecated since you wrote your answer? –  Greenonline Feb 21 at 17:46

I like to use 123dcircuits.io for this.

It's cloud based and has some nice features including PCB design and collaboration.

IMO the Arduino simulation and capability is impressive and intuitive.

It is very nice and clean and basic functionality is really impressive, easy to use and powerful. However many common parts (including LCD and temperature sensors) are not supported yet. I doubt you can test anything but very basic designs at this stage. I hope this will get better over time. –  Suma Aug 7 '14 at 14:07
    
I gave it a quick try and found it very impressive for a free product. I don't know its limitations in terms of simulation realism, but the editor is very friendly and just placing a led into the proper slot automagically created code with the correct pin and a blinking loop! –  heltonbiker Mar 26 at 20:20

Yes you can, try using Proteus ISIS for simulating your code...
For full emulation of Arduino, there is shareware program called VBB, I tried it too and it was nice. You can find it here

You can use Yenka (free for home use) to simulate Arduino, PIX, PIXACE and other boards with digital, analog and serial I/O. It provides a lot of components and sample projects.

Try Simulator for Arduino - it is the best but then we are biased since we are part of the development team. Not everyone wants to pay $14.99 although almost 5k Arduino users have in the last few years. There is a free version of Simulator for Arduino which runs for 30 days or 100 sketch loads and 150 lines max. Try this and then buy if you can afford it and/or if it seems worthwhile. If there is something not right or which could be improved, let us know - everyone else does and has which is why Simulator for Arduino has been 99% built by user ideas and bug reports. Timer interrupt and 7 segment LED display coming in v0.99E

Also, the only other program we have tried which comes close in quality is Proteus but this is a full PCB design studio and looks to be very expensive - ie much more than $15. And we plan to ignore a recent user request to increase the price to $200.

Virtualbreadboard has a new VBB4Arduino 'Two Arduino's' edition which includes BOTH a JVM Arduino emulator AND a AVR Instruction set simulator with examples that cover almost all of the Arduino distribution examples and a bunch of peripheral hardware - LCD's, WS2812 Neo LEDS, Motors, Servo's, Logic Analyser and more.
